The startup company was founded by Dan Gilbert, Josh Luber, Greg Schwartz, and Chris Kaufman starting in 2015, and launched in February 2016. Scott Cutler and Schwartz serve as chief executive officer and chief operating officer, respectively, and Deena Bahri became the company's first chief marketing officer in 2019.
