42Floors

Market position

42Floors positioned itself as an office-space search engine emphasizing listing accuracy and presentation quality, competing against established commercial real estate listing and data platforms. Third-party sources name LoopNet, CoStar Group, VTS, Ten-X, Xceligent and Crexi as comparable companies. One source characterizes the company as having built a better product but being structurally constrained by brokers' control of listing data and transaction relationships, and describes its end state as a feature within an incumbent database company.

Sources identify four claimed differentiators: aggregation of office listings from both landlords and brokers, including coworking spaces and sublets, in a single search experience; detailed data and professional photography with an interface described as clean and consumer-grade relative to incumbents such as LoopNet; a deliberate sequencing strategy of saturating San Francisco data before expanding to other markets; and backing from top-tier venture investors plus a network of commercial real estate professionals as angel investors, which aided credibility and listing access. One source argues that these advantages were primarily aesthetic and did not by themselves create a defensible business against brokers who controlled both listing data and transaction relationships.

Technology

A web-based listings search platform with filtering by size, type and price, professional photography and structured property data. A third-party profile lists the site's technology stack as including Gravatar, Cloudflare and Cloudflare CDN, WordPress VIP, Open Graph, Shopify, Bootstrap, and a Responsive Lightbox & Gallery extension.

Go-to-market

Early go-to-market centered on Y Combinator participation, direct engagement with the commercial real estate community, and signing up landlord and broker partners to grow the listings database, with the founder having obtained a commercial broker license to understand industry mechanics. The seed round deliberately included ten commercial real estate veterans as angel investors to signal industry buy-in. Growth was market-by-market, saturating San Francisco data before adding New York and other major U.S. metros. Post-acquisition, the site is distributed through Yardi's CommercialEdge network, where clients manage, market and syndicate listings.

Businesses, startups and entrepreneurs seeking to rent office space, coworking space, sublets and executive suites, with an explicit focus on smaller tenants underserved by traditional brokers. Listing-side customers were landlords and brokers. Under Yardi, the platform serves tenants, investors and commercial real estate professionals.

Geography

Headquartered in San Francisco (address listed as 501 Folsom Street, #400), with one source also noting remote operations. The company started in San Francisco, expanded to New York, and stated it covered every major market in the United States. In January 2013 it announced plans to expand internationally, beginning with London by the end of that year. Under Yardi, the relaunched site covers listings nationwide across the U.S.

History

The company was incorporated in November 2011, participated in Y Combinator's Winter 2012 batch, and launched publicly in March 2012. It raised a seed round in November 2011, a Series A in November 2012, and a Series B in January 2013, and expanded from San Francisco to New York and then to every major U.S. market, with a stated plan in 2013 to enter London. Attempts to operate as a broker in 2014-2015 are described as unsuccessful. Knotel, a flexible office provider, acquired the company in July 2018, framing it as a data and technology acquisition. Knotel filed for bankruptcy in early 2021; the 42Floors brand subsequently passed through a real estate private equity firm and was purchased by Yardi in December 2021 from Roni Mova, principal of United Group. Yardi redesigned and relaunched the site as part of the CommercialEdge marketplace network and redirected the domain to CommercialCafe.com in May 2024.

Risks & controversies

One source characterizes 42Floors as unable to overcome a structural constraint in commercial real estate: brokers controlled both listing data and transaction relationships, leaving the search layer difficult to monetize; its 2014-2015 move into brokerage is described as having failed. Reported figures also conflict across sources — total funding is given variously as $17.4M across three rounds, roughly $12M across five rounds, and approximately $30 million in venture capital; founding year is listed as 2011 in most sources but 2010 in one; and one aggregator erroneously dates a Yardi acquisition to 2011 and lists Knotel's acquisition as 1 January 2018 rather than July 2018. Its acquirer Knotel filed for bankruptcy in early 2021.
