OP says they would conduct user interviews. Our process looks a lot like this and user feedback is incorporated in these idea sessions because we're constantly getting feedback via email and phone conversations with customers -- the stuff a lot of users ask about gets remembered, considered, and discussed in these planning sessions. In general I think the job of founders and product people is to build/delegate building, talk to customers, and repeat based on what customers are saying. Is there a better way?
