I have not. The continuous integration infrastructure at megacorp was merely a symptom of some major cultural problems that over the course of a few years just weren't going to be addressed to my satisfaction, so I left. Paying for Cloudbees was a painful exercise, and I think the guy that was pushing for it ended up getting shitcanned. After all, the whole point of deploying Jenkins was to avoid paying for TeamCity.
For my personal stuff, I haven't looked at buildkite primarily because I'm looking for free, open source solutions. The secondary (but no less important) issue is that I'm also looking for coverage for *BSD. Buildkite lists FreeBSD support so, assuming it's not a Linux binary expected to run under the translation layer, they could presumably offer binaries for the other BSD variants. Right now I've got some buildbot workers setup on some bhyve VMs with df/net/openbsd and some jails with FreeBSD.
The big thing I've noticed is that lots of tools will list FreeBSD support at least, but few of those claims are actually tested. Even fewer mention any of the other BSDs. For example: Elixir deployments on FreeBSD have been broken for months; Hashicorp put out a FreeBSD build of their vault ssh helper that didn't work by design -- but they had no idea because they never tried to validate the build; rust's libc crate lists FreeBSD, NetBSD, and OpenBSD as tier 1 platforms, but they're only testing the crate on an old version of FreeBSD (where they've disabled some key tests due to a misunderstanding rendering the tests not super useful)... plus they're not in a good position to deal with the C ABI changing between releases.
