Without using Google I can tell you at least 3 companies that already receive Monero as payment : IVPN[2], AirVPN[3] and TorGuard[4]. As a sneak peak I really believe that Mullvad is going to start accepting Monero payments in the near future given this sneaky "like" noticed by a fellow Reddit user[5]: https://i.imgur.com/AbuTRtg.png
Regarding Mullvad and Monero, their tweet [1] from yesterday is again revealing and they refer to our website [2] + [3] where there are mullvad voucher codes for monero (and bitcoin).
