Menlo Park just scored another high-profile recruit in the AI land grab. Hippocratic AI, a fast-rising healthcare-technology company, is leaving Palo Alto and planting a much bigger flag in the city, at a moment when deep-pocketed AI firms keep snapping up the strongest office space in an uneven Silicon Valley market.
CoStar first reported yesterday that Hippocratic AI is relocating its Silicon Valley headquarters to Menlo Park and tripling its footprint in the process. The company is moving into 4300 Bohannon Drive, shifting its base from Palo Alto to the Peninsula city in a clear bet that its growth story now needs real square footage, not just pitch decks and product demos.
The Registry reported that the lease covers 30,857 square feet at Kilroy Realty's Menlo Corporate Center, a roughly 378,000-square-foot multi-building office and life-science campus. This is not a startup camping out in hot desks and phone booths; the deal gives Hippocratic AI room to build a real operating base.
Hippocratic AI Is Growing Out Of Its Startup Shell
The larger headquarters comes backed by serious capital. In its Series C announcement, Hippocratic AI said it raised $126 million at a $3.5 billion valuation, bringing total funding to $404 million. The company also said it has partnerships with more than 50 health systems, payors and pharmaceutical companies across six countries.
That money is now showing up in hiring plans, not just on cap tables. In June, a release via PR Newswire announced a six-month LLM model-training residency for engineers, dated from Menlo Park. The program is aimed at pulling experienced software engineers into frontier-model training work, a clear signal that the Menlo Park office is meant to be a build-out hub, not a satellite sales outpost.
Menlo Park Pulls Ahead In The Peninsula Office Recovery
Hippocratic AI is landing in one of the Peninsula's healthier office markets. According to Kidder Mathews, Menlo Park's direct office vacancy rate was 12.9% in the second quarter, or 14.3% when all available space is included. The city logged 216,566 square feet of year-to-date net absorption and an average asking rent of $7.05 per square foot, the highest among the Peninsula submarkets tracked in the report.
Those numbers help explain why a well-funded healthcare AI company would lean into expansion rather than wait for an even softer market. CBRE reports that tech and AI companies leased more than 14 million square feet across San Francisco and Silicon Valley in 2025, and that AI firms alone have leased roughly 21 million square feet in the two markets since 2019. Both markets also have more than 5 million square feet of active demand from tech and AI tenants looking to expand, relocate or renew.
In other words, the best spaces are not sitting around waiting for cautious founders. Companies with fresh capital that move quickly can still secure well-located blocks of space, as Hippocratic AI is doing.
Peninsula Winners And Losers Split On Vacancy
The rebound, however, is far from universal. The same Kidder Mathews report pegged Redwood City's direct office vacancy rate at 36.5% in the second quarter, several notches above Menlo Park's. In that softer market, voice-AI startup Retell, taking 13,346 square feet at 540 Price Avenue, made headlines, but it was a much smaller commitment than Hippocratic AI's Menlo Park move.
Hippocratic AI's larger lease underscores a pattern: companies with significant new funding and aggressive hiring road maps are cherry-picking premium properties, while other buildings stay stuck in the post-pandemic limbo.
Menlo Park's economic development office casts the city as a hub for venture capital, technology and innovation, anchored by Sand Hill Road and major employers such as Meta and Robinhood. Hippocratic AI's relocation fits that storyline neatly. A healthcare AI startup with deep pockets is moving closer to the Peninsula's talent and investor networks, while pulling a sizable chunk of office space back into active use. For a city trying to cement its role in the AI economy, that is exactly the kind of vote of confidence it wants on the board.
