A Silicon Valley company that makes artificial intelligence software for businesses has tripled its office footprint near California's technology capital.
Uniphore, which says it makes “AI coworkers” for big companies that help them optimize customer communications, has expanded its headquarters at the Stanford Research Park in Palo Alto on the heels of a funding infusion. It moved from a 9,500-square-foot space housing about 95 employees at the 1001 Page Mill Road business park to a 26,661-square-foot office in a neighboring building designed to accommodate more than twice as many workers, “with room to grow as demand continues to accelerate,” the company wrote in an email to CoStar News.
Uniphore launched in 2008 in Chennai, India, and expanded its home offices to Northern California in 2019. The company is backed by big tech players including Nvidia, Snowflake and Databricks as well as an array of old-world investors such as NEA, March Capital, BNF Capital, National Grid Partners and Prosperity7 Ventures with a valuation of $2.5 billion after a $260 million funding round in October.
The startup is in the midst of a furious expansion of its U.S. operations. Late last year, it announced the acquisition of another Silicon Valley firm, Orby AI, and plans to acquire another startup called Autom8 as it aims to bolster its automation capabilities. The company this week announced a deal with accounting and professional services giant KPMG, in which it will provide AI agents with small language models.
Uniphore is more than a maker of chatbots, it designs tools intended to partner with human employees and improve processes by analyzing data such as customer service calls.
“Over the past year, we’ve experienced steady, 100% growth year-over-year, fueled by widespread enterprise adoption of our business AI platform,” a Uniphore spokesperson told CoStar. “Increasing our presence in Palo Alto enables us to further invest in talent, innovation, and closer collaborations with customers and partners throughout the region."
But the firm clearly has global ambitions. In June, it announced an expansion across Europe. Uniphore maintains dual headquarters in Palo Alto and Chennai, with additional offices in Israel, Spain, Dubai and the U.K. It has more than 800 employees around the world.
Who's who of tech tenants
Despite its prestige as one of the Silicon Valley’s most vaunted and expensive office locales, Stanford University’s home city of Palo Alto has grappled with the same real estate headwinds as the rest of the San Francisco Bay Area in recent years. It still posts an elevated vacancy rate of almost 18% in the first quarter of 2026, reflecting the lingering effects of tenant downsizing and space returns from major tech firms over the past two years. However, leasing momentum has improved recently, and rents have continued to rise, signaling cautious optimism about the future.
Demand from artificial intelligence tenants has helped send leasing volume in the greater San Francisco area to levels not seen since 2019, according to CoStar data. Net absorption, or tenant move-ins minus move-outs, turned positive at the end of 2025, and the region's vacancy rate fell 30 basis points to 21.7%.
Stanford Research Park dates from the early 1950s, when the university partnered with city officials to set aside more than 200 acres for research and development use by pioneering companies to generate income for the university and stimulate economic development. Today it encompasses 10 million square feet of office and lab space across 140 buildings, housing over 150 companies. Firms that are alumni of the site include Hewlett-Packard, Lockheed Martin and Facebook.
The office campus at 1001 Page Mill Road is owned by Palo Alto-based developer The Mozart Development Co. Other AI firms that have been housed there include Rubrik, a company that provides cloud security, and Cloudera, a data platform.
In September, real estate firms Harvest Properties and TPG Real Estate purchased a 13-building, 1.1 million-square-foot office campus from Broadcom in a deal that real estate services firm Newmark dubbed “the largest property sale on a square-footage basis in Stanford Research Park history.”
