RKT

Rocket Companies, Inc.

A Detroit-based fintech that runs one of the largest mortgage businesses in the United States, Rocket Companies owns Rocket Mortgage, real estate brokerage Redfin, the Rocket Money app, and Rocket Loans. It began in 1985 when a 23-year-old Dan Gilbert used savings from delivering pizzas in college to start Rock Financial, a Metro Detroit mortgage broker. The company later became Quicken Loans and, in 2015, launched Rocket Mortgage, a name chosen to signal speed and simplicity.
