Whether the non-technical guy is uncommitted depends on how much money he is sinking in. Ponying up the cash is an important and legitimate contribution.
If someone drops 1 mil to build an app I would say they are committed.
I'd offer that $1M would qualify Non-technical as an accredited investor. I'm more interested in the person who can offer up, say $100k, give or take, to support the development and launch of a MVP.
