AI startup Prometheus has leased six floors of the One Harrison office building to consolidate its headquarters in San Francisco. The expansion follows a $12 billion capital raise that boosted the company's valuation to $41 billion earlier this summer.
Why it matters
The move reflects a shift toward office spaces designed with high-capacity electrical systems for AI hardware and robotics. It also signals a potential turning point for local office demand, as the city's vacancy rate recently dipped to 27.7%.
The One Harrison property is a 180,000-square-foot facility purchased by The Sobrato Organization for over $80 million. Prometheus currently operates out of a 30,000-square-foot office at 101 Mission Street and a 100,000-square-foot warehouse in West Oakland.
The players
Prometheus
An AI startup co-founded by Jeff Bezos and Vik Bajaj in 2025 that specializes in hardware-intensive technology and robotics.
The Sobrato Organization
A major real estate investment firm that purchased and renovated the One Harrison office building.
The Gap
A national clothing retailer that owned the One Harrison office building for over two decades.
The details
The building was renovated by The Sobrato Organization to include an electrified HVAC system and a lobby green wall while prioritizing open floor plans for flexibility. These upgrades were essential to support the heavy power requirements of the hardware-intensive robotics technology developed by Prometheus. The design omitted traditional amenities like a gym to ensure the space could accommodate the necessary computing infrastructure.

The Home Front
This move highlights a broader trend in San Francisco's commercial real estate market as firms pivot to buildings retrofitted for intensive technological infrastructure. It offers a counterpoint to the high office vacancy rates that have impacted local property values and commercial tax bases since 2021.
If you live or work near the One Harrison area, expect increased activity as the startup moves into its new headquarters. Residents should monitor local traffic patterns near the site during the upcoming transition period.
The takeaway
The transformation of older retail headquarters into high-tech hubs underscores the demand for buildings with specialized electrical capacity. Homeowners should track how large-scale office occupancy changes in their neighborhoods affect local foot traffic and business services.
