If they have some experience managing technical projects, it could work -- there are certainly people that do that. It depends on how much the technology is going to differentiate the product. If it's a straightforward implementation, it's fine. Having a tech co-founder is cheaper in the short-term (for the same skill level). It's only more expensive if you are successful, and it might make that more likely.
