Enterprise AI leader Glean has raised over $260 million in a Series E funding round, bringing its valuation to $4.6 billion. The funding round, co-led by Altimeter and DST Global, included participation from major investors such as Craft Ventures, Sapphire Ventures, SoftBank Vision Fund 2, and seven existing backers. This marks a significant milestone for Glean, which has seen rapid growth since its founding in 2019.
The latest investment comes as Glean continues to expand its Work AI platform, an enterprise search system designed to connect seamlessly to a company’s internal data via more than 100 SaaS connectors. Glean’s platform is already in use by major companies including Reddit, Pinterest, Duolingo, Databricks, and Grammarly, as well as global enterprises in sectors like telecommunications, banking, retail, and manufacturing.
Alongside the funding announcement, Glean has launched several new features aimed at accelerating AI adoption in the workplace. These features include next-generation prompting tools that automate complex, multi-step workflows, accessible to users of all skill levels.
The new capabilities introduced to the Work AI platform include:
Prompt builder: Allows users to create, edit, test, save, and publish prompts using natural language, simplifying the process for non-experts.
Advanced, multi-step prompts: Designed to automate intricate tasks and workflows.
Prompt sharing: Enables users to share prompts with teammates, fostering collaboration and promoting the adoption of AI tools.
Prompt library: A resource for users to explore and discover new AI use cases.
Additionally, Glean has integrated its technology into Zendesk and Salesforce Service Cloud, enabling support teams to serve customers more efficiently and effectively. These embedded solutions represent a key focus for Glean as it seeks to enhance customer service through AI-driven automation.
Co-founder and CEO Arvind Jain, a former Google engineer, expressed excitement about Glean’s growing role in helping large enterprises adopt AI to transform their operations. “To truly unlock new levels of creativity, productivity, and operational efficiency, AI needs to draw on the full picture of an organization’s knowledge – and it needs to be accessible by everyone,” Jain said. “You shouldn’t have to be a prompt engineering expert to find answers, generate content, and automate work with AI.”
Rahul Mehta, managing partner at DST Global, praised Glean’s rapid product development, customer-centric approach, and leadership in enterprise AI. “Their deep understanding of data, powerful search and RAG (Retrieval-Augmented Generation) technology, and exclusive enterprise focus make them a leader in Work AI,” Mehta said.
Since its founding, Glean has experienced a surge in demand for its solutions, driven by companies eager to leverage generative AI across their operations. The company’s annual recurring revenue has more than tripled over the past year, underscoring the growing importance of AI-powered tools in the enterprise space.
Earlier this year, Glean announced over $200 million in Series D funding at a $2.2 billion valuation. The latest Series E round has more than doubled its valuation in just six months, reflecting the company's accelerating growth and the increasing importance of AI in enterprise solutions.
