My company uses it. We have a bunch of seats in an enterprise plan and have been using it for 9 months or so.

It's a great product compared to Copilot. It is also the first AI tool I used heavily outside of creating random images or one off questions.

I'm now using all three, Devin, Claude, Codex. I'm finding Claude and Codex to be much better. One of my biggest gripes is that the web client and desktop client for Devin are two completely different harnesses, so the quality of responses varies greatly.
