Enterprise search startup Glean raises $150M series F funding at $7.2B valuation

Enterprise search startup Glean just secured $150 million in new funding, pushing its valuation to $7.2 billion—up from $4.6 billion just nine months ago, when it raised $260 million in a Series E round.

The round was led by Wellington Management, with new backers like Khosla Ventures, Bicycle Capital, Geodesic Capital, and Archerman Capital joining in. A long list of existing investors also doubled down, including Sequoia Capital, Lightspeed, Altimeter, Kleiner Perkins, ICONIQ, and General Catalyst.

The Palo Alto-based startup says the money will fuel product development, international expansion, and hiring across sales and R&D.  “Since our Series E in September, we’ve crossed $100 million in annual recurring revenue,” said CEO and co-founder Arvind Jain. “Our platform is now trusted by Fortune 500 companies, and we’re just getting started.”

With this funding, Glean also plans to open a new San Francisco office soon to support its growth. Current clients include names like TIME and Booking.com, which are using the platform to bring structure and efficiency to their internal operations.

Founded in 2019 by CEO Arvind Jain and former Google engineers, Glean started as an enterprise search engine using AI assistants and large language models, like OpenAI’s GPT, to provide tailored answers based on a company’s internal data.

That ARR milestone came less than three years after the company launched. Glean was founded by former execs from Google, Meta, and Dropbox—folks who’ve built for scale before. Its core product helps large companies search across internal tools like Google Workspace, Microsoft 365, Slack, and Salesforce. The tech builds a personalized knowledge graph for each employee, aiming to surface more useful results and automate routine tasks.

In early 2025, Glean rolled out Glean Agents, a new AI assistant feature that the company expects to hit one billion actions by year-end. They’re positioning it as a hands-on tool for enterprises looking to shift internal workflows into AI-assisted territory.

The company’s recent Glean: GO conference attracted over 10,000 people, both in person and online. There, it announced new partnerships with Dell, Palo Alto Networks, Snowflake, and Workday. The signal is clear: Glean wants a bigger seat at the enterprise table.

In an interview with CNBC, Jain noted that many enterprise leaders aren’t just curious about AI—they’re worried. “They don’t want to be left behind,” he said. “The key thing I hear is they want to make their workforce AI-first.”

Unlike consumer-facing tools like ChatGPT, Glean is focused on company-specific data. Jain made that distinction clear: “Models like ChatGPT don’t know your internal data. We do. That’s what makes this work for real business needs.”

Still, Glean isn’t alone. The competition is fierce, with Microsoft 365 Copilot, Amazon Q, ChatGPT Enterprise, and newer players like Perplexity and Writer in the mix. Glean’s edge, Jain says, lies in its deep integration with enterprise workflows and its ability to work alongside, rather than compete directly with, tools like Anthropic’s Claude.

“Google, Microsoft, OpenAI—they all want in,” Jain said. “But we’ve been here, building from the ground up. And we’re not chasing something that’ll be a commodity a year from now.
