Wireguard has taken third party funds to expedite development, but as far as I know the author is pretty adamant all the implementations are freely available and open source, so maybe angel funds aren’t the best direct way forward.

Disclaimer: I’m a principal at Latacora and we paid the author some money to make native Mac clients happen. There’s also a VPN provider who paid money toward development.

I’d rather they did it right than rush it to meet a kickstarter date.
