Loose Cubes

Loosecubes, Inc. was a membership-based marketplace often described as the "Airbnb for shared office space" — it connected people looking for a place to work with companies that had vacant desks and coworking space. Founded in 2010 in Brooklyn, New York by Campbell McKellar (Walmsley) and Anna Thomas, it raised roughly $9M total, including a $7.8M Series A led by New Enterprise Associates with Revolution Ventures and Battery Ventures participating. The company shut down and permanently closed in late 2012. This profile was surfaced as a Battery Ventures portfolio lead; enrichment found no live API surface — the business is defunct and the loosecubes.com domain is now held by an unrelated owner.

Loose Cubes is profiled on the APIs.io network. Tagged areas include Company, Coworking, Real Estate, Marketplace, and Workspace.
