Glean, the enterprise AI startup often cast as a rival to Microsoft’s Copilot, has quietly grabbed more office space near downtown Mountain View as it ramps up hiring and product work. The expansion is another sign that fast-growing AI outfits are still staking claims in the South Bay even as the broader office market keeps reshuffling after the pandemic.
According to the Silicon Valley Business Journal, Glean has taken additional space in the neighborhood and now counts roughly 1,000 employees, just seven years after it was founded. The outlet reports that the new lease fits into the company’s ongoing build-out in the region.
Glean has also been busy on the fundraising front. CNBC lists the company on its 2025 Disruptor 50 list and reports that the startup has raised about $765 million to date, capital that has helped it hire aggressively and grow its footprint. Those funds have given Glean room to speed up both product development and its go-to-market teams.
What Glean Builds
Glean develops an AI-powered enterprise search tool and assistant that indexes a company’s internal documents, chat logs and apps so it can surface answers and automate workflows. That puts it in direct competition with Microsoft Copilot and other enterprise AI products, according to reporting by The Economic Times. Glean’s pitch leans on the security controls and deep integrations that large enterprises expect when they roll out AI across sensitive systems.
Mountain View’s AI Office Boom
The Mountain View office market has seen several big AI moves this spring, including OpenAI’s multibuilding lease at the 350-380 Ellis Street campus, underscoring why startups keep parking engineering and research teams in the city. Local reporting indicates that developers and owners are retooling Class A space to lure major AI tenants, a trend that mid-sized players like Glean are taking full advantage of.
Glean has been expanding internationally as well, and its CEO has described a sizable India build-out as part of broader growth plans. The larger Mountain View footprint is the latest physical signal of that push as the company keeps scaling its engineering and sales teams. For nearby landlords and downtown businesses, that could translate into more hiring, longer lunch lines and a livelier weekday scene around the city center.
