We crossed our first milestone of this campaign with $350K+raised and early bird terms officially sold out! We got here thanks to nearly 300 investors who believe that it’s time to electrify factory heat.The momentum showed up on the leaderboard too. Out of 330+ companies raising Reg CF last week, Airthium landed in the Top 5 most raised on Wefunder and #15 across all platforms nationwide according to Kingscrowd! While the early bird allocation is now closed, you can still access discounted terms through Wefunder’s VIP program. For all other investors, today’s valuation will be our lowest valuation, and best entry price, from this point onwards. With many more milestones on the horizon, we’re focused on the development and validation of our 10kW 180°C engine, which opens up a larger market segment and proves our concept. This is the time to get in or double down on Airthium → wefunder.com/airthium/invest Thank you to everyone who is fueling our progress!
