Knock Ranks No. 369 on the 2021 Inc. 5000

Inc. magazine announced that Knock is No. 369 on its annual Inc. 5000 list, the most prestigious ranking of the nation’s fastest-growing private companies. The list represents a unique look at the most successful companies within the American economy’s most dynamic segment—its independent small businesses. Intuit, Zappos, Under Armour, Microsoft, Patagonia, and many other well-known names gained their first national exposure as honorees on the Inc. 5000.

“We’re incredibly proud to be honored on the Inc. 5000 list, especially to find ourselves ranked in the top decile of an already elite group of companies. The result is a testament to our ‘one team’ philosophy, and the demand for innovation in proptech right now,” said Demetri Themelis, co-founder and CEO at Knock. “To us ‘one team’ means seeking out and building ‘everybody wins’ solutions. We’re always thinking about our customers, their customers, our team members, our partners, our investors, their investors–the entire multifamily industry, one of real estate’s best-performing subsectors. The big question now is what impact the solutions Knock is developing beyond CRM will have on our customers’ business performance–perhaps that will push us into the single-digit rankings territory next year!”

See how Knock broke into the multifamily business with a three-month road trip and “every hangover cure imaginable.” Read Inc. magazine’s feature with CEO and co-founder Demetri Themelis about he and Tom Petry, cheif product officer, started Knock.

Not only have the companies on the 2021 Inc. 5000 been very competitive within their markets, but this year’s list also proved especially resilient and flexible given 2020’s unprecedented challenges. Among the 5,000, the average median three-year growth rate soared to 543 percent, and median revenue reached $11.1 million. Together, those companies added more than 610,000 jobs over the past three years.

Complete results of the Inc. 5000, including company profiles and an interactive database that can be sorted by industry, region, and other criteria, can be found at The top 500 companies are featured in the September issue of Inc., which will be available on newsstands on August 20.

“The 2021 Inc. 5000 list feels like one of the most important rosters of companies ever compiled,” says Scott Omelianuk, editor-in-chief of Inc. “Building one of the fastest-growing companies in America in any year is a remarkable achievement. Building one in the crisis we’ve lived through is just plain amazing. This kind of accomplishment comes with hard work, smart pivots, great leadership, and the help of a whole lot of people.
