I similarly agree 5 is an absurdly low figure. Forget everything else and just consider securing the site, collecting payments globally, tax, and you've got 15 FTEs right there.
BUT - i'm at a VC funded startup and can see how bloated these companies become whilst achieving not much. Our company got VC cash, then the VCs installed a CFO. First thing the CFO did was demote most of the engineering staff down to entry-ish level titles.
Then came product managers, program managers, directors of product management, senior directors of program management, VPs of product, and C-suite.
The Product:SWE ratio is 1:2 to 1:5 depending on the team. That is right, since we're falling behind on coding and quality, the obvious solution to hire senior people to go talk at conferences.
Meanwhile engineering headcount and QA headcount barely moved. When product timelines and quality suffered, instead of considering why SWEs were demotivated, they hired more Directors and more Product Managers to micromanage and oversee the efforts. Except the Product Managers are remote and we barely ever hear from them. We think they are product managing their own careers mostly, we see more activity on their Twitter and LinkedIn accounts than we see on Slack.
So what have people done? SWEs jet out of the office at 5, many are running startups on the side, some are consulting on the side.
Next thing you have a several-hundred-person-startup producing about what you produced with 50 people
Fuck me.
