It looks like you guys built a solid product that's clearly useful, as well as a website that makes the value proposition immediately obvious. I would guess that this had more to do with your funding success than your cold email strategy.
Thanks a ton! Indeed having an interesting product helps, but what good is an interesting product if your email gets chucked straight into the trash because it's too long, or seems too arrogant? ;)
Thanks ohazi, appreciated! We still have a long way to go :)
