Founded in 1920, Schlage is a well-known manufacturer of smart locks and security products, with millions of smart locks sold. The company was started in San Francisco, CA, by Walter Schlage, a German immigrant from the Thuringia region.

Schlage was a bonafide San Francisco startup before it was cool! It raised an initial seed round of just $30 (not a typo!) from local investors. Its first office was located in SOMA, where the current Museum of Modern Art stands. The company later moved to the north Mission District of San Francisco, before opening its first factory at the corner of Blanken Ave and Bayshore Blvd in the Visitation Valley in the mid-1920s. Its old Mission-style office can still be seen at this site.

In the 1970s, Schlage was acquired by Ingersoll Rand, and the company was relocated to Colorado Springs, CO, in the late 1990s. Finally, it was spun out as part of Allegion in 2013.

Today, Schlage continues to be known as a leading smart lock manufacturer, with a large share of the market. Its devices are sold in nearly all major U.S. retail channels and are compatible with most smart device automation platforms, including Seam.
