Today, I’m talking with Max Nussenbaum, the former CEO of Castle, a property management startup in Detroit that was using technology to change the game.

At their peak, they had raised $4 million from investors and grew to be Michigan’s second-largest PM company, but in January of 2018 they winded down the business.

In this interview, Max shares the lessons he learned from his time at Castle, where things went wrong, how he would do things differently, and shares lessons that will help you avoid some of the same mistakes.
