Josh Haynam was creating websites with a friend in college–an easy way to make some money. Clients often had random requests like, could you make a quiz about what kind of salesperson you are? There was nothing he liked better than an interesting problem. That led to him co-founding and self-funding Interact, a quiz software used by 40,000 brands including The American Red Cross, Forbes, and Home Depot. Interact is one of the fastest-growing marketing software firms in the world.
