Reference excerpt

Glean Technologies, Inc. is an American technology company specializing in enterprise-grade artificial intelligence (AI) and search capabilities. According to Reuters, its valuation is $7.2 billion as of June 2025.

History The company was founded in 2019 in Palo Alto, California. In September 2021, Glean introduced its assistive search tool, designed to pull together information from dozens of disparate applications, streamlining access to critical data across various platforms, to the market. In February 2025, the company reported reaching $100 million in annual recurring revenue. At that time, the company also announced its agent platform, designed to automate workplace tasks beyond search. The platform became generally available in May 2025. In September 2025, Glean introduced a third-generation Glean Assistant and an Enterprise Graph focused on personalization and multi-step task execution. It was named CNBC's top 50 disruptor in 2025.

Products and technology Glean’s platform combines enterprise search, an AI assistant, and AI agents. Its search product integrates with workplace applications to index company data and provide permission-aware results. The AI assistant, introduced in 2021, helps employees find and summarize information across connected systems. In 2025, the company expanded into agent technologies, allowing employees to create and deploy AI agents to automate workflows using natural language instructions.

Funding rounds In March 2019, shortly after its establishment, Glean raised $15 million in Series A funding co-led by Kleiner Perkins and Lightspeed, which included participation from the Slack Fund. In March 2021, the company closed a Series B funding round of $40M led by General Catalyst. In May 2022, the company secured a $100M Series C led by Sequoia Capital at a $1B valuation and hit the Unicorn status. In February 2024, Glean raised over $200 million in Series D funding at a $2.2B valuation. In September 2024, Glean raised over $260 million in Series E funding, co-led by Altimeter Capital and DST Global, taking its valuation to $4.6 billion. In June 2025, Glean raised $150 million in Series F financing led by Wellington Management at a $7.2 billion valuation.

Worked examples

Example 1 — a first encounter with Glean Technologies

Start with the simplest possible case. Write down what Glean Technologies claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Glean Technologies before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Glean Technologies ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Glean Technologies

In research: Glean Technologies appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Glean Technologies in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Glean Technologies is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2019 establishments in California, American companies established in 2019, Artificial intelligence companies, so understanding it makes those chapters shorter.
In everyday life: Look for Glean Technologies outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
