QB3@953, a biotech incubator, has been so successful that many of the startups housed there are searching for larger laboratories in Southside San Francisco. But their moves have been stymied by high rents and real estate prices, as well as a lack of space for midsize companies.

The incubator, launched almost two years ago, provides roughly 50 companies with a stylish, comfortable facility, featuring a shared kitchen and conference rooms. It’s located at 953 Indiana Street, across from vacant lots and close to textile and handbag manufacturers.

QB3@953’s location offers easy access to the San Francisco International Airport and Downtown, as well as proximity to the University of California, San Francisco. Larger tenants, such as L’Oreal and GlaxoSmithKline, provide advice and equipment to their smaller neighbors. “None of them want to leave. All of them want to stay in San Francisco,” said Douglas Crawford, associate director of QB3. “They have this Catch-22. They need data to get money, and they need money to get data.”
