More specifically: non-sales-driven tech startups with founders who don't have their own money to fund development by working with employee-programmers, directly employed or outsourced.
If you read that and thought "you can't employ that programmer, they have to be a cofounder"? Then add in the criteria that you're aiming at a "tech-heavy market", rather than building a webapp for a non-technical need.
(As an example: while I respect patio11 greatly, I suspect that the actual Bingo Card Creator webapp could have been developed by a good programmer from some decent sketches, at least in beta.)
So basically this article targets business people with little money and a "great startup idea!" that they can't build themselves. I fully believe there are a lot of those out there, but it's still a fairly narrow category...
