Granola Raises $125M Series C at $1.5B Valuation

Granola, a London-based AI note-taking startup founded in 2023, raised $125 million in a Series C round on March 25, 2026, achieving a $1.5 billion post-money valuation. The funding was led by Danny Rimer at Index Ventures, with participation from Mamoon Hamid at Kleiner Perkins, alongside existing backers Lightspeed Venture Partners, Spark Capital, and NFDG. This marks a sharp increase from its $250 million valuation in a $43 million Series B round in May 2025, bringing total funding to $192 million across prior rounds including a $20 million Series A in October 2024 and a $4.25 million seed in May 2023. Granola's platform transcribes meetings locally on users' computers without visible bots, generating summaries and now advancing toward enterprise features like team workspaces, APIs, and integrations with tools such as Anthropic's Claude Code.

The capital enables Granola to scale its pivot from a prosumer app for individual note-taking to a full enterprise AI infrastructure, turning company conversations into queryable context for organizational knowledge. Customers already include major firms like Vanta, Gusto, Thumbtack, Asana, Cursor, Lovable, Decagon, and Mistral AI across compliance, fintech, project management, developer tools, and AI sectors. This unicorn milestone underscores investor confidence in Granola's rapid growth amid the AI productivity boom, positioning it to compete by embedding meeting data into broader enterprise workflows. Rimer will join the board as an observer, signaling strategic guidance for this expansion phase.
