We're a bootstrapped 7 figure SaaS company and we've never had a dedicated support team, instead everyone at the company does support one day a week. I haven't heard of many other companies doing that, but it's worked out great for us.
More details on why we do it in a recent blogpost. But I'm curious if others are considering it? Happy to answer questions.
Good for you!
You can learn a lot from staying close to your customers. We've handled our own support for 8+ years now and we're also a 7 figure SaaS company (2 person team).
