## Story
At WeatherFlow-Tempest, we’re helping everyone from Fortune 100 businesses to homeowners make smarter decisions with real-time, hyperlocal weather intelligence.Weather impacts everything — from how we grow food and manage power grids, to countless decisions made every day.Our proprietary weather technology and state-of-the-art hardware provide actionable weather insights that save money, time, and resources.Built on a growing foundation of 85,000+ weather stations, WeatherFlow-Tempest operates the largest managed weather network in the world, producing billions of observational data points every day. Our continuously evolving Nearcast AI™ and our best in class data decision tools optimize cost savings and efficiency for more than 150,000 customers.Led by world-class weather scientists and proven business innovators, we’re raising capital to fuel our next phase of growth, capturing the growing demand for more sophisticated weather intelligence from consumers, businesses and government agencies.Weather is the force impacting everything we depend on — from food and water to transportation and energy. Yet countless daily weather-related decisions rely on incomplete or imprecise data, driving massive inefficiencies across the global economy.While disasters steal headlines, the hidden impact of weather is incalculably large. Every year, businesses and households squander hundreds of billions of dollars in wasted energy and water, lost productivity, and avoidable property damage as a result of under-informed decisions.Weather impacts global industries, AND it shapes everyday life at home. Utilities are often underprepared for fire danger. Your air conditioner still runs even as temperatures drop. Sprinklers pump water even as rain approaches. A soccer team drives to practice when it’s already dangerously hot.We can’t control the weather, but our weather intelligence technology transforms it to something we can anticipate and proactively manage. The result is reliable support for smarter decisions in both automated processes and those that require human oversight, eliminating waste and generating real additional value.Our Proprietary Weather NetworkOur solution starts with the world’s largest managed weather network - a carefully supervised set of weather stations with every data point continuously validated and quality controlled. Today, this growing network includes over 85,000 stations generating billions of daily observations. These stations are located in the areas of greatest demand for improved weather info, from homes, farms, and commercial operations to remote locations such as coastlines and power infrastructure, giving us unparalleled reach and precision for all our customers.Nearcast AI™ Fuels Smarter Weather IntelligenceWe combine data from our network with all available curated surface observations to create a vast, high-quality dataset that powers our patented Nearcast AI™. This system continuously validates incoming data, calibrates instruments, and fills gaps to generate high-resolution, localized weather insights, even in areas with limited direct observations. By integrating real-world measurements to correct errors and biases, it also enhances Numerical Weather Prediction (NWP) models, delivering forecasts that are more accurate than any other source. Nearcast AI™ transforms all available observations into a data-to-decision system powering consumer apps, enterprise platforms, and application programming interfaces (APIs) with precise, actionable insights.The Network data fuels Nearcast AI™ and together they drive a proprietary intelligence platform that powers all our hardware and software products. This technology delivers clear, actionable weather insights that save time, protect what matters, and help you make smarter decisions-every day, in every season.With WeatherFlow-Tempest’s suite of products, apps, and data visualization tools, utilities see shifting winds before a fire has the chance to spark. Homes automatically adjust AC and irrigation to run only when it makes sense. Coaches reschedule practice to avoid dangerous heat. Massive risk and waste are avoided.Our team brings together world-class experience in weather sciences and business innovation with a series of successful exits and private-public partnerships. From NOAA to Silicon Valley, our team is obsessed with leveraging data and design to improve the future of weather.We’re addressing a total market opportunity of approximately $20 billion across data services, forecasting, IoT hardware, and climate analytics. Various sub-markets are expanding at double-digit rates as businesses, governments, and consumers seek hyperlocal, actionable weather intelligence.The existing market is changing as customers are demanding more. The world is more data driven than ever, and our company is poised to provide more products with actionable measurable insights. WeatherFlow-Tempest is uniquely positioned to lead this new era of short-term, hyperlocal weather intelligence – locally and globally.Streamlining operations and fine-tuning our diversified revenue mix have strengthened our financial performance, enabling us to deliver operating profit since Q2 2025 while continuing to invest in innovation. Today, we are positioned to fund steady growth from operating cash and accelerate expansion as high-value opportunities emerge.Each branch of our business is advancing as an independent revenue driver.

Our always expanding network, combined with the ongoing advancement of Nearcast AI™, is fueling exceptional YOY growth in software and data services. ARR at year-end 2025 now exceeds $1M, up more than 85% from 2024.Looking ahead, we believe 2026 will be a breakout year for WeatherFlow-Tempest. We're preparing for a significant consumer app launch in April. With new partnerships forming and international expansion underway, we anticipate substantial growth across all business lines.We are raising capital to scale rapidly, prioritizing proven markets in emergency management, utilities, media, and insurance, as well as high-potential sectors such as commercial property, construction, and smart energy. All our areas of focus offer long-term gains where our competitive advantages are strongest.Big tech and global strategics continue acquiring companies that blend hardware, software, and data intelligence — the same model we’ve built at WeatherFlow Tempest.Recent billion-dollar exits in weather, data, sensors, and smart-home intelligence, show a clear pattern: companies that control unique data and deliver real-world utility create enormous value.With our rapidly expanding, proprietary weather network and AI-driven decision tools, we’re building the same kind of defensible asset that has powered these major acquisitions. We’re all at the mercy of the weather. But the future of weather is here. At WeatherFlow-Tempest, we’ve built a global weather intelligence platform that helps the world get smarter about how we manage and react to it.With our rapidly expanding network, AI infused technology, data advantage and strong recurring revenue, we’re positioned for exponential growth. Our foundation is solid — the start-up business and technology risks are behind us. Opportunity and a plan to grow lie ahead.We believe we are at a transformative inflection point - our company has strong traction and a profitable model yet we are just beginning to take full advantage of our opportunity to expand growth decisively and capture a much larger share of the opportunity in front of us. We invite all our customers, weather geeks, and savvy investors to join us!

## FAQ
1. **Hello, I have invested in all of your prior rounds on StartEngine. Why would I reinvest when the investor updates have been at best lackluster, and you have not verbalized a plan to provide a return to investors? I look forward to your response.**
   - Thanks for backing us across multiple rounds. Your support has helped us materially strengthen the business. Hopefully you are receiving our quarterly investor updates - I'll check with my team to make sure and also add you to our monthly newsletter list. In case not, here's a quick overview of what we've achieved this year: - Recurring B2B revenue is accelerating and forming the backbone of a high-margin, scalable business line. Consumer revenue is also well positioned to grow in 2026. - Nea...
2. **Have you already reached the first $500K of investments. I went to invest and the share price was $4 instead of the $3 per share**
   - During testing the waters (pre-Form C filing), Wefunder’s UX does not allow the share price on the wefunder.com/wft/invest page to reflect the Early Bird terms. This is because the final assignment of the Early Bird terms is based on the ordering of confirmed investments, after the Form C is filed. At this time we are still within the Early Bird allocation so if you reserve an investment and then confirm immediately after we file our Form C (which we expect to happen in the next 24 hours), th...
3. **Any financials available for Y2023 and Y2024?**
   - Yes! Audited Financial Statements are included in our Form C, which we expect to file later today. Our offering will be live at that point and any "Reserved" investments can then be confirmed.
4. **Like Mr Blundell I invested in prior rounds thru StartEngine. So what happened to my original $453 investment? Do I own shares or was this money spent and gone. Why would I invest more money when I don't see any benefit or loss for that matter from my original investment? I lo...**
   - Thanks for being a past investor! You've helped us build a great foundation, and we've now reached an inflection point. We believe we are just beginning a period of rapid growth on our successful journey. You own equity (shares) in our company, like myself and my colleagues, though you own preferred shares. And the liquidation preference associated with your preferred stock means you would receive a return of funds before common stock holders receive any benefit. Any return on investment woul...

## Q&A
- Q: Four key questions that would help me and others evaluate this opportunity: 1. In one simple sentence, what are you working on? 2. Why are you doing this, what is your personal visceral connection to the problem? 3. Why now? 4. What is your unfair advantage?
  - A: Hi Jarek! Great questions that get to the core of what we do and why it matters. Simply put, we’re sharpening and extending the proprietary weather intelligence platform we’ve already built. Many of us have spent years turning weather data into actionable, proven insights. The key is delivering measurable value, preventing waste, improving outcomes, and ultimately yielding better financial performance for our customers. Knowing we will help the planet along the way is a meaningful bonus. We’ve been waiting for this moment. Low-cost connected sensors can now provide quality data, enabling our massive crowdsourced but managed network. Efficient data processing, and advanced AI make our approach both scalable and cost-effective. You’re right to suggest we have an unfair advantage. We don’t have a direct competitor and we are successful across several existing categories: - We sell consumer and prosumer weather stations, but unlike other companies we also include these stations in a managed network, curating and quality-controlling the data. - We offer consumer weather apps that cater to localized use cases. Our specific data offers unique value, allowing us to focus on subscription revenue, rather than advertising like more generic weather apps. - Our fastest growth comes from weather-oriented SaaS, API, and App tools for businesses. Unlike other services, we rely on billions of proprietary daily local observations and the Nearcast AI technology to provide the particular insights valued by our customers and prospects. Our moat is how these elements work together as a unified platform: - An exclusive, managed weather network: We operate the world’s largest fully quality-controlled private weather network, now at 85,000+ stations and growing. That scale and data density took years to build and becomes more valuable with every new station. - Hardware + data + AI: Our sensors, network management, and Nearcast AI™ were designed as a single system. That allows us to deliver site-specific accuracy competitors simply can’t match by stitching together third-party data. - Network effects that widen over time: Every new Tempest system improves data quality and forecasts for everyone (consumers and businesses alike). That compounding data advantage is extremely difficult to replicate. - A proven bridge from consumer to B2B: Consumers help us scale the network efficiently; that network unlocks high-margin B2B SaaS and data licensing. The two sides reinforce each other in a virtuous cycle.
- Q: Hi, I own one of your products and really like it, but there is so much information thats not here or clear to me from an investor perspective. If any of the questions I post is somewhere, please advise where. Here are some questions: What is your current annual revenue and growth rate? What percentage of revenue is recurring vs hardware sales? Are you profitable today? If not, what is monthly burn? How does this round extend runway (months)? Who do you see as the most likely acquirers? Have you had acquisition discussions in the past? What dilution should investors expect in the next round? Is there any planned secondary liquidity for Reg CF investors?
  - A: Great to hear you are fan! We tried to put most of that information on the Campaign Page but happy to share a summary here. Our current annual revenue is about $13m and we will soon show an operating profit for our third straight quarter. Over the past 12 months we have focused on three main goals I) illustrating that our model is profitable ii) continuing to grow our Network and advance our Nearcast AI based solution and product offerings iii) utilizing improved solution and product offerings to grow revenue from business customers, particularly annually recurring revenue. We have been successful with all three. Flat revenue from Hardware Systems in '25 will still yield more than 20,000 units sold, expanding our Network. Our solution and products improved, and consequently the B2B ARR under contract now is more than 80% higher than a year ago. Since we are past the initial stages of business risk we no longer face a "runway". We are raising capital to take full advantage of growth opportunities across all our product categories. We often field inquiries about acquiring our business. For now we are laser focused on creating a valuable business and creating liquidity for investors at the optimum time.
- Q: Hello, I have invested in all of your prior rounds on StartEngine. Why would I reinvest when the investor updates have been at best lackluster, and you have not verbalized a plan to provide a return to investors? I look forward to your response.
  - A: Thanks for backing us across multiple rounds. Your support has helped us materially strengthen the business. Hopefully you are receiving our quarterly investor updates - I'll check with my team to make sure and also add you to our monthly newsletter list. In case not, here's a quick overview of what we've achieved this year: - Recurring B2B revenue is accelerating and forming the backbone of a high-margin, scalable business line. Consumer revenue is also well positioned to grow in 2026. - Nearcast AI™ Technology is delivering enterprise-grade insights, which is why utilities, insurers, and smart-home partners are engaging and expanding with us. - We believe our foundation is complete. Our network is the largest managed network of its kind. I view each new Tempest as strengthening the moat around our business. - We have proven our model is profitable. We have a clear plan to scale B2B ARR and expand all business lines across the globe. We are focused on creating returns for shareholders. The key is building a large, profitable company with significant recurring revenue powered by B2B SaaS, data licensing, and a consumer engine that expands our network while contributing healthy margins. Our future success will allow us to maintain optionality for a strategic sale or an eventual public listing. My colleagues and I are also shareholders, aligning our goals with yours. We are excited by the current point in our company’s trajectory. We’re transitioning from building the foundation and proving the business model, to scaling up a defensible, high-margin business that delivers measurable ROI for consumer and enterprise customers (energy saved, water saved, operational efficiency increased). This value creation at scale is what ultimately will drive investor returns. You believed in us early, and would be grateful to have you with us again in this next stage – this is the moment where that early conviction can compound.
- Q: At what point does this become an investment that can be transferred as a stock to a major trading platform such as Schwab, Fidelity, or E-Trade? I understand the reasoning for an SPV but I do not want an SPV and would transfer as soon as possible.
  - A: Thanks for the thoughtful question. Your shares will not become publicly traded at purchase and therefore would not be transferable to a brokerage platform. An SPV holding your shares is a Wefunder standard. It's a structure also sometimes used by venture investors for consolidating capital for a single targeted investment. For now we are laser focused on creating a valuable business. Assuming we are successful, we intend to pursue liquidity for all us who are shareholders at an optimum time in the future. This could mean that our shares become publicly traded, or it might mean a sale or another mechanism for creating liquidity.
- Q: Have you already reached the first $500K of investments. I went to invest and the share price was $4 instead of the $3 per share
  - A: During testing the waters (pre-Form C filing), Wefunder’s UX does not allow the share price on the wefunder.com/wft/invest page to reflect the Early Bird terms. This is because the final assignment of the Early Bird terms is based on the ordering of confirmed investments, after the Form C is filed. At this time we are still within the Early Bird allocation so if you reserve an investment and then confirm immediately after we file our Form C (which we expect to happen in the next 24 hours), these terms will be shown in your final investment contract.
- Q: Now that the funding round has closed, just checking on the status of the investor perks offered? Haven't heard anything so far.
  - A: Emails are going out next week! Keep an eye on your inbox.
- Q: Hello, Who is your direct competitor in this space and differentiator/moat?
  - A: Great question. We don’t consider any other company a direct competitor. We compete indirectly in different categories: 1. Consumer and Prosumer weather station companies that sell hardware but don’t operate a managed station network with curated, quality-controlled data. 2. Consumer weather app offerings that most often rely on generic data and less localized use case specific data, most with a primary focus on advertising over subscriptions. 3. Weather oriented SaaS, API, and App vendors that don't have billions of proprietary daily local observations or the Nearcast AI technology to provide the particular insights valued by our customers and prospects. Our moat is the is how these elements work together as a unified platform: 1. An exclusive, managed weather network: We operate the world’s largest fully quality-controlled private weather network, now at 85,000+ stations and growing. That scale and data density took years to build and becomes more valuable with every new station. 2. Hardware + data + AI, designed together: Our sensors, network management, and Nearcast™ AI were designed as a single system. That allows us to deliver site-specific accuracy competitors simply can’t match by stitching together third-party data. 3. Network effects that widen over time: Every new Tempest system improves data quality and forecasts for everyone (consumers and businesses alike). That compounding data advantage is extremely difficult to replicate. 4. A proven bridge from consumer to B2B: Consumers help us scale the network efficiently; that network unlocks high-margin B2B SaaS and data licensing. The two sides reinforce each other in a virtuous cycle. In short, our differentiators are data scale, data quality, and deep operational know-how (in addition to our patents and algorithm). We’ve reached critical mass, and from here the gap widens.
- Q: Thank you Buck for the detailed response — very helpful. One clarifying question that would help me finalize my decision: Approximately what is the current B2B annual recurring revenue (ARR) under contract today, and what percentage of total revenue does it represent? If possible, it would also be helpful to understand whether this ARR is primarily multi-year contracts and whether customer concentration is diversified or weighted toward a small number of large clients. Thanks again — appreciate the transparency.
  - A: No problem, Fernando. Happy to answer your questions! We strive to be transparent while also maintaining competitive advantage. Today, we have 250+ active subscribers across our B2B SaaS and Data-as-a-Service offerings, with ARR now exceeding $1M. We serve a diverse customer base, ranging from small co-op utilities and local emergency management to some of the nation’s largest organizations, including industry leaders like Amazon and Disney. This is easily our fastest growing revenue category, reflecting a go-to-market push that has been prioritized now that we are beyond a critical mass with our network and we have developed the products the market is demanding. Our campaign page outlines the growth we are building toward and why we’re raising capital at this stage. While outcomes are never guaranteed, it’s worth noting that the appreciation of common stock is the primary way our team will gain compensation, which directly aligns incentives with those of our investors.
- Q: What if I want to sell my position?
  - A: Hi Jeff - You can find more info on reselling shares via the Wefunder platform FAQ page (see link below). Reg CF investments are long-term, illiquid, and you should assume you’re holding until a major liquidity event. My colleagues and I are also shareholders, aligning our goals with yours. https://help.wefunder.com/after-you-invest/304329-can-i-easily-re-sell-my-investment?from_search=211732839
- Q: Like Mr Blundell I invested in prior rounds thru StartEngine. So what happened to my original $453 investment? Do I own shares or was this money spent and gone. Why would I invest more money when I don't see any benefit or loss for that matter from my original investment? I look forward to your response.
  - A: Thanks for being a past investor! You've helped us build a great foundation, and we've now reached an inflection point. We believe we are just beginning a period of rapid growth on our successful journey. You own equity (shares) in our company, like myself and my colleagues, though you own preferred shares. And the liquidation preference associated with your preferred stock means you would receive a return of funds before common stock holders receive any benefit. Any return on investment would likely come at a time we sell the company or go public (or there is another secondary market for shares). We don't have a specific plan for that day yet but the company is clearly more valuable than when you invested. We’d be honored to earn additional investment from you. Although results can’t be guaranteed, our focus remains the same: increasing the value of your existing stake and building toward strong future returns. We appreciate your support!
- Q: Any financials available for Y2023 and Y2024?
  - A: Yes! Audited Financial Statements are included in our Form C, which we expect to file later today. Our offering will be live at that point and any "Reserved" investments can then be confirmed.
- Q: Well, the damn thing just died in my backyard... How do I get the 35% discount? :)
  - A: Hi Alex! Please reach out to our customer support team and they will take care of you! https://help.tempest.earth/hc/en-us/requests/new
- Q: I have invested a second time, another $2500 and have not received any confirmation could you please look into this and let me know where the money went. Thanks Jeff Fitts
  - A: Hi Jeff! I've confirmed your investment increase. The additional amount is currently pending but should clear in the next couple of days. Thanks!
- Q: Perk status? How do I claim/exercise the 35% discount? Thanks in advance.
  - A: Hi Bruce! An investor update and perk emails are set to go out very soon, with instructions to redeem your tier's perks. For more specific info or other questions in the meantime, please reach out: ceo@weatherflow.com
- Q: Hi WeatherFlow-Tempest Team, Impressive to see profitability coming through alongside network expansion and growing B2B revenue, as well as the highly-dedicated customers and community you've built over the years. As you deploy capital from this round, how do you think about the tradeoff between continuing to expand the physical network vs. focusing on scaling higher-margin data / enterprise revenue? Which has actually been the more efficient growth lever so far? Thank you.
  - A: Thanks! Creating positive EBITDA was an important goal for the past 12 months. As we invest more in the future, focusing on maximizing long-term value of the company, the synergy between network expansion and enterprise revenue is the key. And they drive each other! Nonetheless, you are correct to imply that revenue growth in high margin recurring revenue is our most important focus at the moment. Our network has reached a critical mass. Moreover, a modest increase in revenue from Tempest System sales (or even flat sales) creates a large increase in the size of our networks. Each new station increases the density and quality of our dataset, which directly improves forecast accuracy and unlocks more value for enterprise customers. That, in turn, drives stronger demand and higher value on the data and SaaS side. In short, we deploy capital to optimize the system as a whole in an attempt to maximize enterprise value.
