Glean just hit $300 million in annual recurring revenue, tripling the figure it posted just 15 months ago. For an enterprise AI company navigating a landscape where CFOs are increasingly skeptical of AI spending, that’s a notable trajectory.
The Palo Alto-based startup crossed the $100 million ARR mark in early 2025. It doubled that to $200 million by December 2025. And now, as of late May 2026, it sits at $300 million, a growth curve that makes most enterprise SaaS companies look like they’re standing still.
How Glean carved out its lane
Glean’s pitch is different, and it’s working precisely because enterprises are getting smarter about what AI they actually need. The company built what it calls a permissions-aware knowledge graph, which is a fancy way of saying it indexes a company’s internal data while respecting who’s allowed to see what. In English: it gives employees AI-powered search across all their company’s tools without accidentally surfacing the CEO’s salary to an intern.
The platform supports more than 15 large language models through what functions as a neutral integration hub. Rather than locking customers into a single LLM provider, Glean lets organizations pick and choose.
