It offers near-zero emissions and unprecedented support for nearly any liquid or gaseous fuel.Fuel Agnostic: REV Force + STLTC engines reliably operate on hydrogen, methanol, ethanol, ammonia, JP-8, gasoline, diesel, and field-mixed fuels with minimal or no modifications, unlocking new market segments and simplifying logistics for global OEMs and end users.Modular, Scalable, and Production-Ready: Built with standard components and manufacturing processes, REV Force can be rapidly integrated into existing supply chains, reducing cost and time to market.Together, these technologies create the cleanest, most adaptable engine system able to replace conventional ICEs, run on clean fuels like hydrogen and ammonia, and when paired with axial flux motor technology, generate electrical power at efficiencies equal to or better than fuel cells and gas turbines. A real innovation able to bring new life to the future of the internal combustion engine.Alpha-Otto's Revolutionary&nbsp;Technology Explained:Driving 4 Answers, a YouTube channel known for its in-depth technical reviews for automotive and engine enthusiasts, recently featured Alpha-Otto Technologies’ REV Force Engine Architecture, explaining what makes it so unique and revolutionary.Direct Market OpportunityThe global market for internal combustion engines, which encompasses everything from production to service across various major sectors, exceeds $500 billion. When we factor in related industries such as transportation and fuels, the total market size reaches into the multi-trillion-dollar range. Our engine technology is versatile and designed for scalability across all application sectors. Even a small-scale adoption of our engine technology—less than 1%—will represent a multi-billion-dollar market opportunity.A Strategy for SuccessThe internal combustion engine industry has been around for over a century and is dominated by many large, well-established companies. These companies either completely dominate specific market segments or maintain a significant presence across several sectors. For Alpha-Otto to succeed and compete effectively, it is essential that we adopt a collaborative market-driven approach to proving and demonstrating the capability and value of our technology.Furthermore, developing and commercializing new engine technology is a costly endeavor. As a result, our go-to-market strategy focuses on establishing relationships and forming strategic partnerships with major engine industry original equipment manufacturers (OEMs) who recognize that our technology can provide them with a competitive advantage or align with their strategic goals. Additionally, we plan to introduce our own product offering, which will help demonstrate and validate our technology.Active Discussions with Major ManufacturersWe are currently engaged in ongoing discussions with several major engine manufacturers. Large engine manufacturers typically take a conservative approach to business and require extensive validation before investing in new technologies. As a result, these discussions can take time. However, our technology has generated significant interest.Our objective is to advance these efforts over the next one to two years, with the goal of securing Letters of Interest (LOIs), engineering services, or similar development agreements. Ultimately, we aim to establish licensing agreements or strategic partnerships with one or more leading engine industry OEMs to introduce our technology into major market segments and across various applications. These efforts may ultimately lead to an acquisition by a large engine OEM.An Ingenious Market Introduction StrategyMeet the Power Cube—designed to be one of the Cleanest, Smallest, Most Powerful, and Efficient Power Generators available on the market.Our flagship product, the Power Cube, is designed to be a truly fuel-flexible power generator—pushing the boundaries of what's possible with multi-fuel capability. It boasts exceptional power density and can run efficiently on almost any fuel, including net-zero carbon-emission options like hydrogen and methanol. The Power Cube combines our revolutionary engine platform with commercially available axial flux motor technology to create an ultra-efficient hybrid-electric powertrain. This innovative system is capable of generating up to 100 kilowatts of power from a one-square-meter unit, weighing approximately 100 kilograms or around 250 pounds.Why A Power GeneratorFirst, the engineering required to calibrate and control an engine used to drive an electric motor to generate electricity is significantly less complex than that of one in a vehicle. And specifically, Alpha-Otto’s engine technology pairs very well with highly efficient axial flux motor technology, creating an incredibly compact and efficient hybrid-electric powertrain.Secondly, stationary or auxiliary (backup and mobile) power generation is not a critical application without inherent redundancies. This makes stationary power generation an excellent real-world application for testing and demonstration. Additionally, large grants are available from governments and industry to finance the demonstration and pilot testing of clean and renewable power generation technologies, such as the Power Cube running on hydrogen, ammonia, or another net-zero carbon emissions fuel. These grants are an important source of capital to underwrite the costs of early-stage production, testing, and real-world demonstration and validation of Alpha-Otto's engine technology.Lastly, developing highly efficient hybrid-electric powertrains is a key part of our strategy to redefine the future of the internal combustion engine. As the world shifts towards electrification, the hybrid-electric powertrain—a combination of an internal combustion engine and an electric motor for electricity generation—will become a critical component in hybrid-electric vehicles of all types and an important means of generating electricity for our electrified world. This includes both backup/auxiliary and primary power generation.Another high-potential application for the Alpha-Otto hybrid-electric powertrain is for utility-scale power generation, enabling the development of distributed power generation and microgrids. By stacking and clustering multiple Power Cubes into a single unit, similar to how batteries are arranged in a battery pack, it is possible to generate up to 20 megawatts of power in a space the size to a standard shipping container and at efficiency levels similar to that of large gas turbine generators, at a fraction of the cost.The market potential for this hybrid-electric powertrain technology is significant:There is a $70 billion+ global market for mobile and backup power generators, with significant opportunities emerging for data centers, emergency response, military, microgrids, and distributed generation.There are substantial market opportunities for hybrid-electric powertrains in several forms of transportation, which are all projected to see tremendous growth over the next ten years, becoming an over $400 billion market segment by 2035. A multi-billion-dollar market opportunity projected to exceed $45 billion by 2033 is developing in the application of hydrogen combustion technology to support and enable growth in a future hydrogen economy.&nbsp;&nbsp;A Business Model for A Competitive MarketMany promising engine technology developers face significant challenges in bringing their innovations to the market. These challenges may stem from their inability to advance beyond continuous product development, a lack of perceived value by the mainstream industry that hinders adoption or acquisition, or difficulties in scaling up production due to overwhelming capital requirements.In the highly competitive internal combustion engine market, Alpha-Otto does not intend to compete directly with large original equipment manufacturers (OEMs) or to build new production facilities. Instead, our business model focuses on establishing relationships and forming strategic partnerships with established OEMs. Our goal is to identify opportunities for collaboration through licensing agreements or joint ventures to bring engines utilizing our technology to market on a large scale.The manufacturing and assembly of Alpha-Otto's products, including The Power Cube, will be outsourced to established vendors. The components of the REV Force™ Engine Architecture&nbsp;are not uncommon or unique to manufacturers and suppliers in the engine industry. This allows Alpha-Otto to scale initial production and product sales using existing suppliers while minimizing capital requirements.&nbsp;What Gives Alpha-Otto A Competitive Edge?Competing on benchmarks alone, Alpha-Otto is highly competitive. However, a real competitive edge is defined as more than just better technology that offers improvements measured against a set of common benchmarks; it is also your business model, market strategy, and how you navigate the challenges of building interest in your technology.&nbsp;Alpha-Otto's business model and market strategy explained above are both strategically focused on building relationships with OEMs and bringing an impressive initial product offering to the market, positioned to demonstrate capability and validate our technology.We anticipate that as our technology demonstrates its capabilities, interest from industry, investors, and the media will grow rapidly. This, coupled with our ongoing engagement with industry OEMs, presents a strong path for success and a competitive market strategy.*Forward-looking projections are not guaranteed.TractionSecured $1.2 million in U.S. Federal Grants through a prior company, which funded the research and development of the REV Force™ Architecture.&nbsp;&nbsp;Designed, built, and tested two generations of prototypes, validating the science and methodology behind the REV Force™ Architecture.&nbsp;Designed and built control systems for calibrating and testing the unique REV Force™ Architecture and Spark-assisted Turbulent Low-Temperature Combustion methodology.&nbsp;&nbsp;Built and tested four engineering prototype test properties.&nbsp;&nbsp;International and US patents were filed in August 2022 and issued in December 2024.ValidationCompleted more than 240 hours of testing on generation one and two prototypes.Ran prototype engines on various octanes of gasoline, pure ethanol, and kerosene using port fuel injection without any modifications to the engine architecture.&nbsp;Ran the generation two prototype on&nbsp;CNG (compressed natural gas) and LPG (liquified petroleum gas), only needed to swap the fuel injectors.Successfully operated the engine on 100% pure hydrogen using low-pressure port injection and air-to-fuel ratios as lean as 50:1 and 70:1, resulting in near-zero NOx emissions.Emissions testing on gasoline showed a 30% reduction in CO2, nearly zero NOx, and a decrease in all base emissions, resulting from more efficient and complete fuel combustion.&nbsp;TimelineSpeed to market is a crucial factor in determining the viability of new engine technology. As mentioned earlier, Alpha-Otto has successfully completed several milestones in the development and testing of our innovative engine technology. While there is still much work to be done to fully understand the potential of this new engine architecture, we anticipate having a minimum viable product or commercially demonstrable prototype ready within the next twelve months. With your support and adequate funding, our initial design—a two-cylinder, 600cc, 127kW engine—will be ready for small-scale production (100-500 units) and early commercialization through demonstration and pilot testing projects within 36 months. For those familiar with powertrain development, this timeline is impressive and represents an incredibly fast pace to market.This timeline is achievable by leveraging existing engineering and streamlining testing, calibration, and engineering requirements for power generation applications and low-volume production. Unlike large-scale manufacturers that must meet stringent standards before retooling their production lines, Alpha-Otto's focus is on pilot testing and demonstration projects that showcase the viability and potential of our technology to attract interest from potential strategic partners and licensees.*Forward-looking statements are not guaranteed.A Visionary TeamOur vision focuses on revolutionizing a crucial technology we depend on every day.

## Q&A
- Q: Hi, I am fascinated and intrigued by your development and definitiely open to investment. One thing I haven't seen mentioned is the comparative cost of mnufacture of your engine versus current technology - maybe I missed it but do you have figures to show this as it is obviously an important factor in the potential adoption in place of the existing technology. Are you still taking investment despite now being oversubscribed? Many thanks, Andy Falconer andy.falconer@drewlear.co.uk
  - A: Hi Andy, Thank you for your thoughtful message and interest in what we’re building. We’re excited to have your support. You're absolutely right that cost is a critical factor in driving adoption. One of the inherent advantages of our engine architecture is its simplicity. By eliminating the traditional four-stroke valvetrain, our system uses approximately 40% fewer mechanical components. This not only reduces complexity but directly translates to lower manufacturing costs. That said, it's still early in the commercialization process, and providing an exact cost comparison is difficult at this stage. Final cost will ultimately depend on the application-specific power output and the scale of production. However, we’re confident that, especially at volume, our system will offer a significant cost advantage over conventional engines, particularly in high power-to-weight applications. And yes, you can still invest. While the round is technically oversubscribed, many reservations have not yet been funded. It is essentially first to fund, first in, so there is still an opportunity to secure a spot in this round.
- Q: I'm a Formula SAE engineering student in Brazil, and this project is amazing! Amazingly, it mostly fits the competition regulations. Would you consider licensing the production of the engine? There is a lot of demand for new engine technology here, and the country has the raw materials for it. Are you already working on cars and motorcycles powered by this incredible engine? If not, the Brazilian market would surely love multi-fuel engines, especially considering our ethanol production. What do you need to speed up progress? Specifically, what will you immediately spend any investments you receive on? Best of luck. I hope to see this engine in production one day!
  - A: Hi Bruno, Thank you for your interest in our engine technology. We're still in early development, currently focused on electric power generation demonstrations. Our commercialization strategy involves licensing to engine OEMs globally. To accelerate progress, we're raising investment, which will help finalize our control systems and expand testing. We invite you to invest and support bringing this innovative engine to market.
- Q: Your 2-stroke engine design, featuring a rotating valve, has really caught my attention, especially since 2-strokes offer significant horsepower in a compact package! Given the unique valve layout, I'm curious: how does the torque curve compare to that of a conventional 2-stroke engine? Considering the high-RPM nature of 2-stroke engines, is your design with a rotating valve any quieter than a 2-stroke motor of similar cylinder displacement? Also, I'm wondering if there's a 'sweet spot' for maximizing power versus minimizing fuel consumption. My reason for asking is I was wondering about something like a BMW i3 with Range Extender (REx) – an all-electric car with a small gasoline engine that acts as a generator to extend the car's range – where the objective is traveling the longest distance possible using the least amount of hydrocarbon fuel.
  - A: Thanks for the thoughtful question, Ben! You're absolutely right to note the unique advantages and challenges of 2-stroke engines. Our engine design delivers a broad, flat torque curve across a wide speed-load range, even outperforming many traditional 4-strokes in flexibility and low-end torque. Unlike conventional 2-strokes, which often rely on tuned expansion chambers that create a narrow "power band," our architecture isn’t constrained by pipe tuning. This allows us to support a wide range of combustion strategies and maintain performance consistency across various duty cycles. To your point on efficiency—yes, there’s definitely a 'sweet spot' for maximizing power while minimizing fuel consumption. One of the strengths of our design is its tunability: we can tailor that efficiency zone depending on the application, whether it's peak power, low-load efficiency, or something in between. We also share your vision of deploying this technology in a range-extending role. In fact, we see massive potential for pairing our engine with carbon-neutral fuels like renewable ethanol or hydrogen to create a highly efficient, low-emission (or zero-emission) hybrid generator. This could be the key to unlocking true energy independence for mobility and distributed power generation. Thanks again for the great question.
- Q: hello, i could not find any Financial statements, please provide us with the proper documents, thanks.
  - A: We are currently in the first phase of the WeFunder investment process, which involves securing reservations from investors. The next step, which we are actively working on, is filing our Form C (the crowdfunding declaration) with the U.S. Securities and Exchange Commission. Once this Form C is filed and approved—typically taking 2 to 4 weeks—a new "DETAILS" tab will appear on our WeFunder page. This tab will provide all financial information and the investment prospectus. At that time, all individuals who made investment reservations will be notified and given the option to convert their reservation into a legal investment according to the terms outlined. WeFunder and the law require us to follow this process and provide all necessary information, financials, and investment terms through the WeFunder platform.
- Q: Are there plans to produce higher cylinder configuration engines such as a 6 cylinder? Looking at the power efficiency of this motor I would be very interested in seeing the numbers for a larger engine. I build race cars and efficiency is key when it comes to racing, this could be a game changer at higher power levels.
  - A: Our current goal is to showcase the technology in the twin platform as a demonstrator, but the architecture has been designed with scalability in mind. As application requirements evolve and partners come online, we plan to engineer application-specific configurations, including higher displacement inline, V, and boxer architectures. This approach allows us to adapt the core technology for a wide range of use cases, from distributed power generation to mobility applications. Larger cylinder configurations, such as a 6-cylinder, are certainly on the roadmap as we scale to meet higher power levels while maintaining the efficiency benefits that set this platform apart.
- Q: Hi there. I don't think I am going to be able to invest in time as my funds are currently locked up coming to the website. Will there be another round when I can invest?
  - A: Hi Reuben, Yes, we are exploring the possibility of conducting another investment round early next year. Please send a message to info@alphaotto.com to request our newsletter, which will keep you updated on our progress and notify you of future investment opportunities.
- Q: I hear the "36 month, two-cylinder, 600cc, 127kW" scope and your answers to @benbalanag, @cwiley about small engines and Range Extenders. I guess around 40kW(e). The useful size of range extenders is limited by how fast the battery can take charge plus instantaneous need. For domestic use this looks like 10% of a car's need. Considering the markets for portable, boat, RV and domestic backup generators in the 1~10kW range: What are your constraints on cylinder count and size? Is it better to design multiple engine sizes, or one smaller (40cc?) design which can be stacked for higher output?
  - A: While our current technology demonstration system centers on a two-cylinder, high-output configuration delivering up to 127 kW, the underlying architecture is designed for scalability. We see strong potential to adapt the system downward into the 5–50 kW range for use in portable generators, range extenders, and backup power applications. At present, much of the demand we’re seeing is in the higher-output space — particularly for systems that can complement intermittent renewables like solar and wind or serve as reliable backup for data centers and critical infrastructure. These applications benefit from the power density, efficiency, and fuel flexibility that our current configuration delivers. That said, we are actively evaluating smaller form factors for Department of Defense applications where mobility, modularity, and single-operator deployment are essential. In this range, we’re exploring both single-cylinder variants and downsized configurations that preserve our core performance advantages while delivering on portability and mission adaptability. Ultimately, your point reinforces our strategy: rather than forcing one engine to serve all roles, we plan to implement this technology into a family of modular, purpose-built platforms optimized for specific use cases.
- Q: A few follow-ups: How did you arrive at the $20 million post-money valuation cap? What are your expectations for a subsequent funding round? With no discount, is it your view the $20 million cap is already generous to investors? How deep into your timeline do you expect this $950k to take you and how much do you think you'll need at your next raise?
  - A: Hi Matthew, We set our $20m valuation cap based on stage, market, and appeal to the Wefunder community. We recognize that this is a generous and highly attractive valuation for a technology like ours, given our market potential. This is why we have capped the raise at $950K. The runway for this raise is 12 to 18 months. We will initiate either a subsequent crowdfunding or VC raise within the first half of 2026. Over the next 2 to 3 years, we will raise $3.5-5m through investment or generate revenue through engineering services contracts with OEMs. We'd be happy to talk with you if you have additional questions. Email info@alphaotto.com to arrange a call.
- Q: Do you have data on longevity e.g. how many hours will this engine last before failure or rebuild is necessary?
  - A: Our current target for Time Between Overhaul (TBO) is 2,000 hours. A major advantage of our two-stroke architecture is the elimination of the conventional four-stroke valvetrain, resulting in approximately 40% fewer parts. This simplification not only improves the power-to-weight ratio but also reduces mechanical complexity and wear, supporting longer service life and easier maintenance.
- Q: How does your engine compare in terms of performance and use cases with LiquidPiston, which first raised here on WeFunder back in 2016?
  - A: We applaud the innovation happening across the industry, including LiquidPiston’s work to rethink engine architecture. At Alpha-Otto, we took a different approach—developing a piston-based engine that enables the advanced combustion reaction process we set out to achieve for high efficiency and fuel flexibility, while also leveraging the existing manufacturing and supply base. The piston-based architecture, with its favorable surface-to-volume ratio, provides superior control over the combustion reaction—an essential factor in achieving low-temperature, high-efficiency operation. This foundation, combined with our advanced subsystems—including forced variable induction, advanced injection systems, and rotary exhaust control—allows us to precisely condition each combustion event. As a result, we surpass the power density typically associated with rotary engines while enabling scalable, real-world deployment—making our platform ideally suited for both distributed power and hybrid mobility applications.
- Q: Thanks for responding to my previous question. Another question I have is relating to efficiency of the rev force engine when compared to an traditional average ICE engine (15% - 42%). Internally, at Alpha-Otto, is there any early predictions or goals for efficiency? P.S - Due to the engine still being a prototype I fully understand if these numbers haven't been realized internally at Alpha-Otto. However, I believe giving a general range for the efficiency would create a great talking point for online forums.
  - A: Thanks again for your continued interest in the details of the technology. Our goal with REV Force is to achieve up to 50% thermal efficiency, well above the range typical of conventional ICEs. This is made possible by our Spark-Assisted Turbulent Low-Temperature Combustion (STLTC) strategy. STLTC enables constant-volume combustion at lower temperatures, increasing pressure rise efficiency while minimizing heat loss and NOx emissions. It leverages intense turbulence and precise spark control to stabilize combustion, all while maintaining the simplicity and responsiveness of a spark-ignited engine. While we’re still in prototype stages, the architecture was purpose-built with this level of performance in mind.
- Q: What's the estimated for time to market for the "Power Cube" listed as the flagship product on your website? What other revenue sources are on the horizon? What's the overall strategy toward becoming at least self-sustaining?
  - A: Hi Ryan, In the next 24 to 36 months, we anticipate deploying a limited number of Power Cubes in demonstration and pilot testing projects funded by industry and federal grants. Our go-to-market strategy emphasizes developing and nurturing relationships with engine OEMs while also producing and offering Power Cubes to the market. Revenue will derive from engineering services and licensing agreements with OEMs, as well as sales of Power Cubes. We expect to be revenue positive within the next 3 to 5 years.
- Q: I look forward to the day this is in consumer vehicles. Before that happens, I hope you consider making a form of these available to hobbyists doing engine swap projects/small volume custom builds. I'm sure it would be great "free" advertisement for your product line attracting OEM attention and building some reliability confidence. (people will put these in everything haha...) Cheers, and best of luck!
  - A: Thank you for the suggestion. We will look into that as we move forward.
- Q: Hello! I’ve already invested because I really believe in what Alpha-Otto is building. That said, I’m doing some due diligence and came across the YouTube creator 2StrokeStuffing, who’s been working on a similar rotary valve concept for years. He mentioned he doesn’t think you copied him, but that he’s concerned your patent overlaps with designs he’s shared publicly — potentially before your filing date. I’d love to understand more about how your patent holds up if someone raises a prior art challenge. Was his design or video ever reviewed during your filing? And is there any legal risk that it could impact the strength or enforceability of your IP?
  - A: Hi Brayden, Thank you again for your support and for taking the time to reach out with a thoughtful question—we genuinely appreciate your diligence and interest in what we’re building. Our core engine technology, including the rotary valve system, has been under development since 2014. We formally submitted our concept to the National Science Foundation in 2018 and had a running prototype by 2019. While the rotary valve is an important feature, our granted patent covers a broader innovation—specifically, our method for managing gas dynamics throughout the cycle to achieve high efficiency, low emissions, and multi-fuel compatibility. We became aware of the YouTube creator you referenced after our technology began receiving broader public attention. While we respect the contributions of others in the engine development space, based on what is publicly available, his approach appears to differ in both purpose and execution. During the review and examination of our patent, extensive prior art—including material that would broadly encompass concepts similar to those he has shared—was reviewed and cited. As with any patent, our claims were carefully examined for novelty and non-obviousness, and we remain confident in the strength and enforceability of our IP. We are committed to maintaining a robust and well-defended portfolio as we continue to grow. Please don’t hesitate to reach out with any further questions.
- Q: Could you provide more informations about emissions? For example what level of EU Euro norm would this engine have.
  - A: When developing our engine technology, it was essential for us to design with both current and future emissions standards in mind, including the strict requirements of the EU’s current Euro 6 and the upcoming Euro 7 regulations. From the outset, we determined that any technology unable to meet or exceed these benchmarks would not be viable. This question is particularly nuanced when we consider the type of fuel being used. Hydrogen, for example, contains no carbon, which means it produces no CO, CO₂, or unburned hydrocarbons. The only potential regulated byproduct is NOx. Our low-temperature combustion strategy, through STLTC (Spark-assisted Turbulent Low-Temperature Combustion), is specifically engineered to prevent NOx formation by managing combustion temperature and mixture formation. This allows us to achieve an extremely clean reaction, positioning our system to meet and exceed even the most advanced future emissions regulations. For carbon-based fuels, there will always be some level of carbon-related byproducts. In these cases, compliance is increasingly dependent on improving thermal efficiency. The more efficiently the engine converts fuel into energy, the fewer emissions are produced per kilowatt-hour or kilometer traveled. Our combustion system is designed to optimize this efficiency, minimizing environmental impact while maximizing performance. Looking forward, we recognize that the long-term viability of internal combustion engines will be closely tied to the fuels they use. You cannot defy physics—carbon-based fuels will always produce carbon-based emissions. To remain relevant in a decarbonizing world, combustion engines must be capable of running on cleaner fuels, such as hydrogen or renewable, carbon-neutral alternatives like advanced alcohol-based or synthetic fuels. That is why our development has focused not only on efficient combustion but also on compatibility with these next-generation fuel sources. This dual approach ensures our technology is aligned with the direction of future emissions and energy policies.
