Our Mission
Create the most valuable communities in multifamily by designing the most enjoyable leasing experience for renters, the most intuitive tools for leasing teams, and the most profitable bottom line for management and owners.

Company History
Knock® was co-founded in 2014 by Tom Petry and Demetri Themelis, long-time friends and Wall Street veterans who were frustrated by their experiences trying to communicate with apartment communities, both as prospects and as residents. They saw an opportunity to create better multifamily technology, and built Knock from the ground up. Their goal was the same then as it is now: help property management companies improve their renters’ and onsite teams’ experiences and increase operational efficiency for the sake of healthier returns.
Knock secured a $10 million Series A round in 2018, led by Madrona Venture Group, and $20 million in growth funding in 2021, led by Fifth Wall Ventures. Today, Knock proudly serves millions of units operated by the fastest-growing management organizations in multifamily, and has been named multiple times to the Best Places to Work in Seattle and BuiltIn Seattle’s Best Small Companies to Work For, most recently in 2022.

Philanthropic Efforts
Knocking Down Housing Barriers
In 2021, the average cost of rent in the U.S. increased by an unprecedented 17.8%, quickly outpacing inflation and wage increases. With continued low vacancy rates, most recently 4.3% in December 2021, the need for affordable rental housing is critical.
That’s why Knock® is helping create an industry-powered housing access fund to address this demand.
The Knocking Down Housing Barriers initiative will raise funds that will provide renters with services to overturn denied applications due to low credit, income, or eviction history. In partnership with OneApp Guarantee, which serves as the co-signer for these renters, we're asking the multifamily industry to join us in helping 10,000 families gain access to housing.
