That's a pet peeve of mine. Adding more people feels more like a company "ego" inflation injected by VCs so they "look good" and valuation goes up. External pressure. It can make good ideas and teams de-rail fast… processes will be introduced, knowledge silos will emerge (because how else would you justify your job in 6 months?), great people will leave because what they don't feel connected anymore. And you rarely observe this in bootstrapped companies.
There's this false pretense that adding more people will yield more "product". And that we need 1 person for infra, 1 person for backend, 1 person for web front-end, 1 person for iOS mobile, 1 person for android mobile, 1 person for… Outsiders only see these "labels" and head counts.
Growth != more people.
(ps. sorry if this looks unfinished and rant-y; I'm not exactly in a good mental space and needed to vent out a bit…)
