a Series C founder DMed me last week asking how our 3 person team does QA. here's the story
It started with a flopped demo, we had a investor call, small startup, me and two other guys. spent two weeks prepping the product and the day of the call, we open the app and the main flow is broken like completely broken, something had changed in a build two days earlier and none of us caught it.
Call went okay but we could tell it rattled them. We didn't get the meeting.
After that i became obsessed, not with hiring a QA person, we couldn't afford it. obsessed with why we keep missing things.
turns out we were testing the same happy paths every time, we were human, we'd check the stuff we built that week, nobody was checking the stuff from 3 months ago that we assumed was fine.
i spent a weekend rebuilding how we do it, not writing a checklist, actually rethinking what needed to happen after every single build without us touching it.
took a few iterations. couple of weeks of adjusting, then it just worked.
We haven't had a regression slip through in 7 months, we ship faster now than before we had any of this set up.
I posted about it here a while back mostly venting. someone from a Series C company DMed me and said their QA team of 6 was dealing with problems our 3 person team had solved.
