Yes, I agree, one or two good engineers should easily be enough, and preferable to a large team. In between having programmers on staff I ended up doing most of it myself. It was not for want of trying, but even getting someone to apply is hard when good engineers were getting dozens of emails and calls from recruiters a week (back then). In the end, doing too much things by myself caused my company to be a bit slower with design updates, not enough attention to marketing, etc. And although there are way more people available who claim they can do marketing, finding a good one turned out to be just as hard. But some things, like well-funded competitors appearing that outspend you on Google Ads, are not under your control. I'm still happy with the end-result though, it's a great life style business.
