Seconding Convox. It's also worth noting that the tooling is open-source, and they profit off an optional-to-use closed-source web interface which has free and paid tiers.

I'm one of two developers at a very young startup, and the one responsible for backend + devops stuff. I simply don't have the time to learn a more complex tool like Kubernetes (not that I didn't consider it) while also working on the actual product. Its simplicity has been a bit limiting on occasion, but they're happy to accept PRs for well thought out changes. I recently had a PR merged regarding UDP ports and ELBs that should make microservice architectures much easier and cheaper to implement.
