That's what I was thinking. I won't be able to afford a "good salary" for a while, and it's still part-time only. I was thinking ~15% and then salary once we're there.
Could a developer do your job plus his own and thus own 100% of the business? Some developers can sell too.
This is not what I suggested . If you want a junior as CTO you can find some in dev bootcamps, universities or startup events.
