I've worked with the founder (Joost H., Remy says Hi). Can vouch for him, all-round good tech guy. He was a Windows server admin at a big cloud provider (CloudVPS), I was one of the Linux guys. He knows his way around Windows, hyper v and clustering. Even some Linux. Quit his job to work full time on the startup with his brother.
Big plus one here. I'd trust wifimask if I wasn't capable of hosting my own servers and needed a VPN.
