We run it ourselves since nov last year (~20k tasks since then, note we are 2 people and bootstrapped).

Then we know a few companies using it w +1k tasks x day (~20/30 people actively using it daily). Then we have some anonymous telemetry too, we are seeing more adoption, but as it's a toggle we only know about the companies that talk w us directly / contribute to the repo.

The type of startups, we generally see tech adopting initially due to the technical deployment required (e.g. k8s), but then tech managers, product, marketing and ops starting to use it more. Connecting integrations, and the Slack integration is super good, works as if it was a peer.
