At home with innovation

Prometheus is a leading multifamily company on the West Coast. Our mission has always been to revolutionize the apartment industry—and that's what we are here to do.

About Prometheus

Home since 1965

Our founder, Sanford Diller, shifted careers in 1965 to invest in the future of Silicon Valley, his lifelong home. He applied a curator’s eye to his business—from craft, to site selection, to management and design.

We believe in giving back. The Bay Area is our backyard. The Promethean Outreach and Community Help program (Our Front POrCH) empowers Prometheans to give back while on the clock. Nearly half of our Prometheans volunteer every year. Sending a little good a long way. Among other grants and gifts, Prometheus donates approximately 30% of our cash flow to a public nonprofit charitable organization established by our founder, supporting education, science and the arts.
