Sean Black

Co-Founder and CEO

2021 Rank: 85

Black leads Knock, which launched in 2015 with a twist on the iBuying business model in which the company made all-cash offers on behalf of sellers’ next home. In 2020, the company, which raised $400 million in debt and equity in January 2019, pivoted to a financing, bridge loan and concierge service that agents from any brokerage could offer to their seller clients. Black previously served as Trulia’s vice president of sales.
