But I also know with experience comes a skeptical eye for being asked to carry extra load for less upside (yet same or more risk).
A story from some time back told to me. Founders had a UI, an algorithm, and an idea. It had merit. They sought someone out to build and run the actual service. The funding was angel, the role was senior to C-level, but the salary offered was 40-60k cut for a senior engineer at the usual suspects, equity capped at 4% assuming a trade off in salary.
Risk and reward to build out infrastructure and productize someone's idea? I could certainly get a couple of people to build it out in a "get us to a-round funding" in those guidelines, maybe even beyond. But as expectations on a non-founding senior/early member, one would assume way too much risk for the potential upside.
It isn't non-technical founder seeking technical co-founder waters, but damn close.
