I listened to a podcast with the founder recently and it sounds like they are trying to go more into that direction, which would be a key differentiator if they manage to do it (rather than just providing a tool to manage feedback/build roadmaps). In terms of "deciding what to build", user research tools such as https://dovetailapp.com/ and https://consider.ly/ might be interesting as well. They are just not positioning themselves towards Product Managers (yet).
