Maybe "mission-chauffeured." Revenue/business model is in the driver's seat and the mission just comes along for the ride and adapts to wherever the car is going.

An entrepreneur I used to admire a great deal was once described to me this way: "So and so doesn't do what's right. He makes whatever he does right." Ever since I heard that phrase, I haven't been able to unsee it in so many founders who I think sincerely want to do the right thing, but their ego gets in the way.
