Oh goodness yes. If I had a do-over, I'd run a straight-up recruiting company with ~0 lines of code written for 2~3 months on the strength of our personal networks, figure out how that works, launch a single tech tree far closer in scope to e.g. Stripe CTF 3 than what we launched, fold candidates developed from that into the recruiting stream, then scale engineering and recruiting in parallel. Instead we went into hard-core dev mode for ~10 months to do something which derisked the business a lot less than being recruiters for a month would have.
Co-founder relationships are co-founder relationships. It's been a stressful year getting a totally new thing off the ground. I think thats a comes-with-the-territory sort of thing based on the reports of literally every founder I know; it is new territory to me. Maybe someday I'll write more about that, but for the moment, still have to figure out recruiting first.
