Aligned interests and motivations are key for this to be successful. First and foremost, who and how will this be funded? If you'd like to create a team to execute on multiple startup ideas at the same time, they'll want to be compensated as you'll have no traction or revenue day one. Also, the best people you'll want on your team might not be interested, as the best like solving difficult problems and now throwing sh*t against the wall and seeing if it'll stick.
