Lots of advice here is to go after pain points, or enter competitive markets, or to question your team dynamics. I have a different perspective:

Set up a studio, where the team builds a new "thing" every 2 weeks. Then, 2 months later you have 4 things, and you can pick the one that inspired the team the most.

Given your cash position, you should be able to easily float 2 months while building a bunch of different things.
