Or don't handle PII, be reasonable with the technical scope of your platform, and have a smaller staff. Bitcoin, for example, was coded by a single person (or at most a tiny group). Even today there are only about 30 people actively writing code for it. You don't need a big team if you link to standard libraries and don't bloat up with gratuitous features.
