The huge sale of Utah-based startup Divvy to Bill.com is still bouncing around my head this week, not only because the $2.5 billion exit was huge for both the company and its local scene, but also because its target market is exciting to watch. Divvy competes in what we call the corporate spend market with a few other unicorns, including Ramp and Brex. This week Brex announced that it is rolling out IRL advertising in a few American cities.
