Glean sells what most enterprise AI projects discover they need and rarely have: a secure, permission-aware map of a company’s own knowledge. It was founded in 2019 by Arvind Jain, a former Google engineer who also co-founded Rubrik, and it started as a way to search across the many tools a company uses. It has grown into the layer that makes other AI genuinely useful at work.
What it does. Glean connects to a company’s internal systems through more than 100 connectors and builds what it calls a context graph — a permissioned picture of where knowledge lives and who is allowed to see it. Search, assistants, and a growing set of automated agents sit on top of that. The result can be cost savings: when AI has the right context up front, it does less work and uses fewer tokens, which lowers a customer’s AI bill at a time when many companies are watching those costs climb. Glean also works with a wide range of AI models rather than tying customers to a single provider.
How it’s growing. Revenue has moved quickly — past $100 million in recurring revenue by mid-2025, roughly doubling to about $200 million, and $300 million reported in May 2026. Headcount roughly doubled over the same period, from about 850 to around 1,650. Customers include Databricks, Reddit, Pinterest, Samsung, Booking.com, Grammarly, Duolingo, and Confluent.
Funding. Glean has raised about $765 million across six rounds, rising from a $1 billion valuation in 2022 to $4.6 billion in late 2024 to $7.2 billion at its most recent round in June 2025. Its investors include Sequoia, Lightspeed, Kleiner Perkins, ICONIQ, General Catalyst, Altimeter, DST, Coatue, SoftBank’s Vision Fund 2, and Wellington.
The current opportunity. That last valuation is now a year old, set against a business whose revenue has roughly tripled since. The more current picture is in the secondary market, and we currently have employees at the company looking for liquidity. If you would like to see what is available, the live book has the current indications.
Worth keeping in mind. Several of the largest technology companies are building similar capabilities, and the most direct competition comes from a product already built into software many companies use every day. Glean’s move to usage-based pricing helps growth but makes revenue harder to predict. And there is no public sign of an IPO yet, so near-term liquidity is not something to count on — part of why the secondary market is currently seeing activity in this name.
