I've met two of their devs randomly in different Discord servers. Both were great people (Noah, Olaf) and are very active in OSS communities. Perhaps not coincidentally, both worked on Language Server related stuff.

Ólafur is responsible for a lot of Scala tooling and some pretty neat original ideas.

Sourcegraph also came up with LSIF, which is useful format for building tooling for language servers:

If you want to build this sort of stuff, the work Sourcegraph has done with LSIF + SemanticDB is probably your easiest bet.

N=2 isn't great, but there's my experiences if we're tossing them out there.
