So I do both tech and business, and I am okay at either - up to a certain level. This has allowed me to build the mvp and start demo'ing it to customers.

The product itself doesn't involve building fundamentally new tech, but mostly leverages/repackages existing opensource tools. So most of the technical skills involved are more devops type than pure dev.

To get to product market fit, I need to bring in other people. I already have a couple of folks to help with business development. Now I also need an engineer to supplement/replace me.

I have a couple of good choices - people with both devops and dev skills that I need. However one of them is purely technical and very good at it. The other also has a devops background but additionally, owned a webdev shop in the past, so they have some skills/sense on the business side as well.

Which sort of profile should I choose? How should I decide? Any pointers will be very appreciated.

Add/edit: all the business dev folks are on commission-only. The new tech person will also be equity-only (might translate to % of revenue as payout). No salary for anyone right now.
