Glean's AI Platform Revolutionizes Corporate Knowledge Management, Secures $4.6 Billion Valuation

Glean's AI platform learns everything to know about your company -- and offers ways to help out

Glean is No. 6 on the list of the World's 50 Most Innovative Companies of 2025. Explore the full list of companies that are reshaping industries and culture. Companies often struggle to mine their own experience and institutional knowledge to stay competitive. When workers don't know where to look for information, otherwise crucial data is useless. That's where Glean steps in, with an LLM-powered assistant built by former Google engineers that allows clients' workforces to unearth and package internal information in useful ways. Think of it like ChatGPT, says CEO Arvind Jain, "but with the additional power of knowing everything about your company." Last year, the company released Glean Work AI, which lets users enter plain language prompts to create AI agents that tackle routine and repetitive tasks. It also deployed retrieval-augmented generation, which forms custom reports from AI-selected snippets of indexed documents. Glean has proven sticky among its users, who return to the app an average of five times a day. The company's annual recurring revenue, meanwhile, reached $100 million in 2024, triple that of the previous year. It also raised $460 million over two funding rounds; the second, in September, pushed the company's valuation to $4.6 billion. Jain says to look out for even more agent-like features in 2025.

What if you could turn your company's vast troves of information -- from institutional knowledge to corporate docs and data -- into an interactive AI chatbot that can pull all that intel together and make it useful for your team? That's the vision behind Glean, a ChatGPT-like tool that CEO Arvind Jain says has "the additional power of knowing everything about your company." And with $100 million in annual recurring revenue last year, plus a $4.6 billion valuation, it seems to be catching on among customers. The firm is one of multiple AI-centric companies that cracked the top 10 of Fast Company's 2025 50 Most Innovative Companies list, an annual ranking of corporate movers, shakers and change-makers driving innovation across the planet. Glean came in at No. 6, with its list entry emphasizing the software's power to help "unearth and package internal information in useful ways" as well as unleash AI "agents" that can take on repetitive tasks. Users return to the app five times a day on average, Fast Company reports, and the platform touts integrations with everything from Slack and Salesforce to GitHub and Dropbox.
