Think about the hundreds of engineers they’d need to hire, purchases for hardware and software, security approvals, etc. that would all need to be spent up front with no guarantee that it’d actually be cheaper. Beating the major cloud providers requires some combination of large scale and/or cutting corners and most companies are not at the point where the infrastructure costs beat the staff time needed.

I used to do ops, costing for infra, build out datacenters, I’m aware!

This sort of thing actually does happen, right? Isn’t that basically what WeWork was, but for all the VC money companies are spending on office space?
