The company I used to work for, used docker-compose to serve its SaaS product to 100+ clients. I wasn't part of that team, but it seemed to me they were quite happy with it.
Can second this: I've seen companies that wanted the benefits of containers but didn't need orchestration yet do just fine with Docker Compose in prod.
Of course, when orchestration became a necessity, almost everyone looked in the direction of Kubernetes, as opposed to something like Nomad or Swarm, probably due to its popularity.
