Glean

Glean's site links to an "About us" page and something called the "Glean on Glean Story," but the page itself doesn't say who started the company or why. So there's no founder origin story to tell here, and we won't make one up. What the site does show is who the product was built for. The featured customers are Booking.com, Zillow, TIME and Ericsson, and nearly every button says "Get a demo." This is software for large companies whose knowledge is spread across dozens of SaaS tools, and it doesn't pretend to be anything else.

The pitch has three parts. First, Glean Enterprise Context pulls in your company's data through "more than 250 connectors" so AI answers draw on your own docs, tickets and chats instead of the open web. Second, Glean Assistant and enterprise search sit on top of that data, with features like proactive AI, content creation, data analysis and a new Team chat (the "October Drop 2026") where colleagues can add context and work on the same output together. Third, Glean Agents let you build, orchestrate and govern agents that act across systems. Around all of it is a control layer: Glean Protect for safety, plus Glean Intelligence with auto routing to the right model, a model hub, usage controls and an AI gateway to govern every AI interaction.

That last part is what sets it apart from a plain chatbot with file uploads. Glean is selling governance and spend control as much as answers, which matters if your security team blocks every new AI tool by default. The tradeoff is clear from the site: no public pricing, no visible self-serve signup, and a solutions menu covering everything from Legal to Higher Education. If you're a 20-person startup, this isn't aimed at you. If you're the IT or platform lead at a company where nobody can find the latest spec, it's worth a demo call.
