If I had a nickle for every time someone on HN claims that a sizable company could be replaced by 1-5 devs, I'd have enough money to start a competitor to most of them that did it better with more devs/staff, as evidenced by the general lack of 1 person saas companies out there that solve more than a very niche problem.
Discord had small engineering team and they outperformed Teams, Google's VoIPs, Skype, Ventrilo, TeamSpeak, Zoom

I'm not at all trying to say you can't have a good product with a small company. It's the incessant "I could do this myself in a month. I won't actually do it, but I totally could" responses. Almost every company you've heard of isn't getting by on single-digit employees, let alone one very smart person.
