When we opened our first Regulation Crowdfunding round, the response was extraordinary. 434 investors joined us to help put everyday radiation protection on the map and HAVN (formerly Lambs) was on its way.

Since that round, the company has transformed. A few of the milestones we've hit:

1. 3x Contracts with the U.S. Air Force — 3 active contracts to protect pilots from radiation, with AFRL support
2. Built real momentum in Washington — 17 letters of support and 8 congressional offices behind EMF-defense legislation
3. Grew revenue from $3.8M in 2024 to target $31M in 2026 — profitably
4. Surpassed 120,000 customers and 1,800 doctors recommending HAVN — now HSA/FSA eligible
5. Launching WaveStopper™ 2.0 — pushing the standards of EMF protection

Now we're scaling manufacturing, expanding into defense and workwear, and growing revenue across consumer, medical and military markets.

The mission hasn't changed. The company has. We're no longer just proving the science, we're deploying it in the field, from homes to the cockpit.

This is your chance to step in at a pivotal moment and help make everyday radiation protection the global standard.

Right now, invisible waves are passing through you, from the phone in your pocket, the router on your desk, the 5G tower down the street.

There are already tens of billions of connected devices on earth, and that number is heading toward 55 billion by 2030.

Over 2,000 peer-reviewed studies have linked this kind of exposure to effects on sleep, focus and long-term health.

55% of people already believe it can be harmful. One in five worry about their own exposure. And the device count only goes one way up.

The science is catching up to what millions already feel: being “switched on” every hour of every day comes at a cost.

HAVN makes the world’s first everyday apparel scientifically proven to block over 99% of the radiation from phones, WiFi and 5G: the same protection now being tested by the U.S. Air Force on its pilots.

Cigarettes. Asbestos. Lead. Microplastics. Each was everywhere before the world admitted the risk and the companies that solved it first were the ones that won.

HAVN is the brand built to own the solution before the rest of the world catches up.

WaveStopper™ is our patented fabric, woven with pure silver fibers that form an invisible shield, blocking over 99% of phone, WiFi and 5G radiation before it reaches your body.

With years of development, millions of dollars invested in R&D, and 12 patents filed to protect the innovation, WaveStopper™ is the only scientifically proven solution to conveniently block EMF in everyday life. The technology’s efficiency has been tested and certificated by independent military-grade Eurofins MET Labs, ensuring its reliability and effectiveness according to top IEEE-299 and EN62209-2 standards.

The U.S. military doesn’t buy wellness trends. It buys what works.

1. 87% higher cancer risk for exposed pilots
2. $1.5B in annual crash-related damage and 3 pilot deaths with radiation investigated as a factor
3. A 2025 DARPA study on cognitive impairment and degraded flight performance from exposure

HAVN is now supported by AFRL, with 17 letters of support and 8 congressional offices backing EMF-defense legislation.

When the Air Force validates your science, the “is this real?” question is over.

1. DTC Consumer — the $420B+ athleisure market, growing ~10% a year. Selling to health-conscious consumers who’ve made wellness a daily habit.
2. Defense & Workwear — pilots, healthcare, industrial, military. Procurement and standard-issue at scale, with a first-to-field advantage.
3. Platform / IP — license WaveStopper™ across apparel, uniforms and home goods. The Gore-Tex model: own the standard, earn on everyone else’s products too.

1. It’s lab-tested and certified to military-grade standards.
2. And it’s soft, washable and built for everyday wear: it keeps working past 300 washes.

1. Wellness, home & travel — blankets, throws, bedding
2. Everyday apparel — beanies, caps, base layers, underwear
3. Workwear & defense — pilots, healthcare, industrial, military

One fabric, protecting every part of your day.

Worn and loved by athletes across the NFL, NBA, NHL and UFC

We hold an unparalleled position in the market as the first and only brand with EMF-protective apparel scientifically proven to protect long-term health and well-being from the impact of EMF exposure. Our customers rave about the peace of mind of using technology while knowing their health and that of their family are protected.

In addition to supporting long-term health, shielding from EMF also has numerous sciencebacked benefits on well-being. EMF exposure can increase cellular and oxidative stress, impacting cognition, sleep, brain fog, immunity, and accelerated aging.

The real-life benefits of HAVN have been highlighted by independent pre-studies. A 2020 pre-study showed that wearing HAVN when exposed to EMF radiation improved HRV - an indicator of the body’s stress level - by an average of 18%.

In 2023, an independent study from the Aspen Neuro Institute used EEG technology to monitor brainwave activity in individuals exposed to EMF radiation from idle smartphones near the head. The results showed a significant reduction in brain stress when wearing HAVN headwear.

The benefits of wearing HAVN have been consistently by our polled customers throughout several years:

$3.8M in revenue in 2024. on track to $31M in 2026. Profitable since 2025.

We project a path toward $150M by 2028 as WaveStopper 2.0 rolls out, and a target operating margin around 20% at scale.

Forward-looking projections are not guaranteed.
