Dunno...one man band here until very recently. I had Github > CircleCI > Heroku automatic deploys on pass implemented on my own with LogDNA + Sentry.io to catch errors and monitor output.

Using Clubhouse to manage mine and the other dev's work now and it all seamlessly links up.

Took at most 30 mins to a few hours to setup each integration. Only downside is the monthly cost of all of the above but in all honesty if even a small startup doesn't have most of the above I'd consider that worrying.
