Have an Angel Network Investment to Announce?

</aside>

📬 "Are Any of These Companies Still Raising?"

It's the most common question we’ve gotten across the 150+ angel deals we’ve featured so far.

Yes. The answer is yes.

So we’ve started testing something new with a few of the angel networks we work with: when we find one that's still open, we push it to their team directly - one deal at a time, deal brief and founder contact included.

Would something like that be interesting to you? Join the waitlist today.

Participating Group: Park City Angels

AccuBreath is developing a handheld ventilator designed to replace the bag valve mask, a manual device used in emergencies to assist breathing that the company says can cause lung damage. Park City Angels recently announced an investment to support the product's advancement through the FDA's 510(k) pathway, a route for clearing devices similar to ones already on the market.
