Glean is the AI-powered work assistant enterprises desperately need

Arvind Jain (Co-Founder and CEO of Glean) speaking at #GenSF earlier this month.

More and more enterprise CIOs who are eager to reap the benefits of generative AI tools —  but are worried about how secure or trustworthy they are — are turning to Glean.  

Glean connects large language models (LLMs) to each enterprise’s unique company knowledge in a reliable and responsible way. Its conversational AI-powered work assistant uses Glean’s powerful search and RAG technology to retrieve the most relevant information for LLMs to generate personalized answers, acting as the connective tissue that unifies stores of information buried deep within every organization. Glean also allows businesses to leverage their troves of accumulated knowledge by building bespoke chat apps using low-code and no-code tools. 

Last year, Glean’s annual recurring revenue increased by 4X, thanks both to expanded use by its existing customer base as well as adoption by industry giants including Sony Electronics. It’s easy to see why: Using Glean’s AI-powered work assistant saves them an average of 2 to 3 hours per employee per week. 

Led by former Google Distinguished Engineer and serial entrepreneur Arvind Jain, Glean offers a turnkey AI search solution for enterprises at a time when they need it most. The company’s growth trajectory is impressive, its potential virtually limitless. For those reasons and many others, we are delighted to announce Lightspeed is co-leading Glean’s over $200 million Series D round with Kleiner Perkins.

A relationship that goes back 20+ years 

We’ve been fortunate at Lightspeed to know and work with Arvind for more than two decades. We first got to know him when he was founding engineer of Riverbed Technology, an enterprise performance platform that went public in 2005. And we got to know Arvind even better when he co-founded another iconic Lightspeed portfolio company, enterprise cybersecurity experts Rubrik.  

We’ve also been long-time believers in his vision for Glean. Lightspeed co-led the company’s $15.3 million Series A round in 2019 and participated in its Series B and C rounds in 2021 and 2022. Our decision to co-lead Glean’s Series D demonstrates both our continued confidence in the company’s mission as well as our commitment to supporting transformative enterprise startups as they scale. 

With this latest infusion of capital, Glean is now valued at $2.2 billion, and Arvind and his team are only just getting started. 

Our approach to growth 

At Lightspeed, we are in it for the long haul. While we delight in identifying founders who aspire to launch market-defining companies, we believe it’s equally important to support companies as they mature and become integral components of the enterprise technology stack. 

Glean is clearly on the path to becoming a standard way large enterprises discover and access internal knowledge, as well as how they implement generative AI tools to improve productivity on an individual level. 

We’re proud to have played an important role in the establishment and growth of Glean, and look forward to what Arvind and his team accomplish next.

Lightspeed Possibility grows the deeper you go. Serving bold builders of the future.
