At Lenny and Friends Summit, Marty Cagan shares ten regrets about his product advice, from underestimating business viability and product leadership to placing too little emphasis on solution discovery. He explains how the pursuit of predictable roadmaps and processes can keep teams from learning what customers need. As AI makes building easier, he argues that clear thinking and a focus on outcomes matter more than ever.
