Ask HN: Which companies use a monorepo (2021)?

Hi, I'm curious to learn which companies use big multi-language monorepos these days? (not javascript "project monorepos", Bazel like things)

If you work in such a company and can share any of the following it's even more interesting: - Roughly how many engineers share the repo? - What languages and tooling do you use? (Bazel? Pants? git? GitHub? Jenkins?) - Do you personally feel like the setup works well for the company? (and is this the general sentiment among engineers in the company?)

Thanks!
