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 2021, it unveiled a cash-backed offer service for buyers. The company, which has been giving signs that it’s preparing to go public, now exclusively provides alternative financing services to consumers in partnership with third-party brokerages.
