Short answer: YES you do need a competent business minded cofounder.

Technology is a component of many solutions to real world problems. It is a common trap to have solutions in search of problems.

Perhaps you could look at your past contracts and identify which industries you enjoyed working in the most. You could then go back and talk with contacts you made in those industries. Based on those conversations you might be able to identify people who have a big problem that you can help create a solution for.

BTW you mention having a couple of devs, etc. Do you have funds to pay salaries for them or do you need the cofounder help you with getting starting capital? The more people you expect to work for 12+ months for sweat equity alone, the less likely you are to be able to successfully launch a new business.
