1 year into my startup and I'm super happy to have kept everything a well-organized monolith. Every once in a while a thing pops up where some voice in my brain (remnants from previous jobs) says "just break it into its own service" but I've thus far resisted. Our deployments are trivial. Our local dev setup is trivial. Maybe some day we'll have a few small services broken off, but today is not that day.
