Wevolver
Wevolver provides access to high quality engineering projects, to help people develop better technology. Their stated mission is to "enable anyone, anywhere to develop hardware that improves life." Wevolver 1.0 was a project repository for strictly Open Source projects, but in 2.0, it has been expanded to include a version control system, and is available for use by private teams in addition to open source projects.
Among the projects using their version control system are OpenROV, Plen, exiii hackberry, and InMoov.
In interviews, Wevolver team members have said the strongest part of their platform is their community, with over 300k followers on instagram, three news blogs, and myriad hosted projects, they've said the most important part of any Open-source platform is the people using it.
