If I decided to build a CRM for the water consultant market, he brings little to the table for me. What I mean I can find a water consultant that isn't him. If I approached him, pitching on the idea for a CRM that would cost 50% less and be 2x more efficient, he'd likely be open to the idea of at least discussing it. If he said no, I'd simply find a different water consultant to talk to. He if said he'd talk, but only if he got to own after I built it, I'd turn him down.
For him to be a viable non-technical cofounder, he'd need to stop being a water consultant, and start being a cofounder. Those are two separate jobs. He didn't want to discuss that. He could bring value, maybe. But he wanted to own the majority of something he couldn't buy or build himself, and he wasn't willing to become a founder. I wasn't interested in doing business like that.
I was once tried being the non-technical cofounder. In the end I decided it was easier to learn how to code, and that path was super hard.
This part I completely agree with you. If you're splitting equality (relatively) equally. He should be as committed as you are, if he's not, than you need to be compensated extra for it.
