I was wondering this as well: Why did OP look for VC?

In my case, I've used a similar strategy of keeping costs under €100/month. (But have sold, or stopped my ventures before hitting such MRRs as OP reports).

I raised some capital to pay my own bills during development. But mostly to hire freelancers to work on parts that I'm bad at, or didn't have time for: advertising, a specific feature, a library, rewrite-in-rust (wink) or deep research into functional improvements.
