Knock Knock is a VR collaboration platform (released in beta to FounderCulture on 2021-09-13) running on Oculus Quest (~$299 per user). It offers shared browsers, JIRA board pulls, games, and both 2D and evolving 3D whiteboarding. Early adopters are asked to use it weekly and provide copious feedback as the team tests session lengths and habit formation toward a full-day remote office.
