Glean
Glean builds an enterprise AI platform that unifies search across a company's applications and data and layers AI assistants and agents on top to answer questions, automate work, and accelerate teams. It was founded in 2019 by Arvind Jain (CEO), Vishwanath 'Vishy' T R, Tony Gentilcore, and Piyush Prahladka; Jain previously spent over a decade at Google as a distinguished engineer and co-founded data-security company Rubrik. Glean's customers include Databricks, Duolingo, Reddit, and Instacart.
Glean reached roughly $100M in ARR within three years of commercial launch and about $200M ARR by late 2025, and raised a $150M Series F in June 2025 at a $7.2B valuation, up from $4.6B nine months earlier, making it one of the most valuable enterprise-AI startups.
