Glean's latest priced round—a $150 million Series F in mid-2025 led by Wellington Management—set its post-money valuation at $7.2 billion, following rapid ARR expansion from roughly $100 million to $208 million by year-end 2025 and $300 million by May 2026. Secondary-market marks have since eased to approximately $6.9 billion as of October 2026, reflecting a modest 4% pullback amid broader private-market caution in enterprise AI. The company’s permissions-aware knowledge graph and shift toward agentic workflows support continued customer adoption and revenue growth at an 89% year-over-year pace, though high multiples near 23x ARR and competition from larger platforms like Microsoft Copilot introduce valuation sensitivity. No new funding rounds have closed in 2026, leaving the year-end outcome dependent on fresh primary or secondary pricing activity before December 31.
