Morning Brew was started in 2015 as a business newsletter written by two University of Michigan students for their peers.

Today, that same email – filled with memes, puns and jokey headlines designed to make business news digestible – is delivered to more than 3m inboxes each morning.

Co-founders Austin Rief and Alex Lieberman, now chief executive and executive chairman respectively, have a staff of more than 100 and multiple newsletters with a combined readership of 3.5m.
