AI startup Prometheus has leased six floors at the One Harrison office building in San Francisco. The expansion allows the company to consolidate its headquarters from its current 30,000-square-foot space at 101 Mission Street.
Why it matters
Prometheus requires increased electrical capacity for its hardware-intensive robotics and AI technology. The building features an electrified HVAC system and improved power infrastructure to accommodate these demanding technical operations.
The 180,000-square-foot One Harrison building was purchased by The Sobrato Organization for over $80 million. The property features a new roofdeck and lobby green wall but lacks a gym to maximize floor plan flexibility.

The Gap
The retail company owned the One Harrison building for over two decades before listing it for sale.
The details
Prometheus, which raised $12 billion this summer at a $41 billion valuation, currently operates from a 100,000-square-foot industrial warehouse in West Oakland alongside its Mission Street office. The One Harrison location previously belonged to The Gap for over two decades before the company listed it for sale in 2023.
Timeline

2025: Prometheus was co-founded by Jeff Bezos and Vik Bajaj.
Summer 2026: Prometheus raised $12 billion and signed a West Oakland lease.

Culture Shift
This deal marks a significant shift as high-growth AI firms prioritize specialized power infrastructure over traditional office amenities like gyms. It highlights a departure from the tenant-driven market of the last decade, as specialized needs for hardware-intensive robotics dictate corporate real estate choices.
The move consolidates Prometheus operations within the city, potentially increasing foot traffic and density near the One Harrison building. Residents and local businesses may see renewed activity as the startup moves into the formerly vacant long-term Gap headquarters.
The takeaway
The arrival of high-capital AI startups to renovated office towers suggests that specialized infrastructure is becoming a key driver for commercial property occupancy. Companies seeking to scale hardware-intensive operations should prioritize facilities that offer significant electrical capacity over traditional office perks.
