AI brain behind your Slack threads: London-based Granola, led by Google alumni, raises $43M

AI is transforming productivity, and one of its most practical applications is reimagining how teams capture and use information. London-based Granola, an AI-powered note-taking and meeting assistant, is at the forefront of this shift. The company has just raised a $43 million Series B funding round to supercharge its mission to turn everyday conversations into living, searchable knowledge hubs for teams.
The investment round was led byNat Friedmanand Daniel Gross through NFDG, with support from existing investors like Mike Mignano fromLightspeed Venture Partnersand Nabeel Hyatt from Spark Capital. The company has also attracted investment from a roster of angel investors, including Guillermo Rauch (Vercel), Amjad Masad (Replit), Tobi Lutke (Shopify), Karri Saarinen (Linear), Lenny Rachitsky (Lenny’s Newsletter), Des Traynor (Intercom), Karim Atiyeh (Ramp), Zach Lloyd (Warp), Charlie Songhurst, Noah Weiss, Romain Huet, Nilan Peiris and Laura Modiano.
This round follows Granola’s $4.25 million seed round and $20 million Series A raised last year, bringing total funding to nearly $70 million. With this funding, Granola plans to expand its team in London to accelerate product development. The company is focused on making it a tool that helps teams work better and think better.
Granola was founded in 2023 byChris PedregalandSam Stephenson, who previously worked across product and engineering roles in startups and tech-forward companies. Their goal is to build tools that capture information and amplify human thinking. With Granola, they’re applying deep AI reasoning to workplace knowledge, helping teams not just work faster, but smarter.
Granola started as an intelligent meeting assistant, combining typed notes with AI-powered transcriptions. The newly launched Granola 2.0 represents a full evolution into a collaborative workspace. Features include:
Granola addresses a core workplace problem: valuable information is often trapped in transient conversations. Meeting notes are inconsistent, and team memory is fragmented. Traditional documents and knowledge bases fall short in capturing the nuance of live discussions. Granola’s solution is to harness AI to make sense of this lost context, organising and surfacing insights that teams can use.
With the launch of Granola 2.0, the platform goes far beyond transcription. It enables users to search across meetings, chat with entire folders of notes, and automatically link conversations to projects, decisions, or client interactions, closing the gap between communication and action.
One of Granola’s most strategic moves is its seamless Slack integration. Rather than asking users to switch platforms, Granola meets teams where they already work. After a call, a concise summary, with links and an AI chat feature, is automatically posted to the relevant Slack channel. This transforms Slack from a noisy communication thread into a dynamic knowledge stream, allowing users to search, reference, and build on past conversations without leaving the platform.
By combining cutting-edge AI with thoughtful UX, Granola is creating a better notepad and a more intelligent, shared brain for organisations.
“Since our launch a year ago, people have started referring to Granola as their ‘second brain’. With Granola 2.0, we’re bringing that power to your entire team, tapping into the most up-to-date, relevant data on what’s happening in your company, the conversations your employees are having day in, day out,” said Christopher Pedregal, Co-Founder of Granola.
“With every call in one place, sales leaders can ask ‘Why are we losing deals this quarter?,’ product managers can investigate ‘Which UX issues come up most often?,’ and recruiters can understand ‘Where do our interviews keep stalling?’ all answered instantly with source-linked citations,” said Sam Stephenson, Co-Founder of Granola.
