How to invest in Glean stock pre-IPO
As companies have adopted more software tools, ranging from Slack to Salesforce to Jira, finding information scattered across applications has often become a challenge for employees. And while AI can help make sense of large quantities of data, there needs to be a way to connect the dots internally, rather than just using chatbots that search the internet. One company that has been trying to solve this problem is Glean.
The company, founded in 2019 by Silicon Valley veterans, has quickly grown into a popular AI-powered enterprise search and agentic solution, with ARR crossing $200 million in December 2025.5 Meanwhile, it has also attracted significant private market capital, most recently raising $150 million at a $6.5 billion valuation for its Series F in June 2025.6
The path forward may be uphill, however. While Glean made a name for itself providing an enterprise search layer sitting between large language models (LLMs) and company apps, it now faces pressure from both sides. Microsoft, for example, is pushing similar capabilities through Copilot across existing Microsoft 365 users.7 Google is similarly doing so with Gemini across Workspace users.8 OpenAI is also expanding into enterprise search,9 as are companies like Salesforce.10
Still, Glean has somewhat of a head start and has already built a significant customer base, including companies like Databricks, Booking.com and Zillow.11
So far, there has not been much talk of an upcoming IPO, but interested investors may be able to invest in Glean stock pre-IPO through a private marketplace like Forge. Retail investors may also be able to gain indirect exposure through other assets, as we will examine in this guide.
Glean: Company background
Glean was founded in 2019 in Palo Alto by Arvind Jain (CEO), T.R. Vishwanath (CTO), Tony Gentilcore (head of product engineering) and Piyush Prahladka (former head of search and AI).12,13 Jain previously co-founded Rubrik, a data security company that is now public, and he spent over a decade at Google. Vishwant previously worked at Facebook and Microsoft; Gentilcore also worked at Google;14 and Prahladka's background includes working at Uber and Google.15
Glean initially built in stealth before launching its enterprise search product in September 2021.16 The main idea is that employees can use natural language to search for answers across all of a company's connected applications, customized to their situation.
In early 2025, Glean expanded beyond search with the launch of Glean Agents, which enables organizations to build and deploy AI agents that can access both internal enterprise data and external data via the internet.17
Glean stock history and funding history
Forge Data as of 06/09/2026
Glean has raised approximately over $700 million across six primary funding rounds since its founding in 2019.18
The company first raised a $15.3 million Series A in June 2019, which implied a $0.58 stock price and $43.71 million valuation. This round included investment from Kleiner Perkins, Lightspeed Venture Partners and Slack Fund. When it released its first product in September 2021, Glean also closed its $40 million Series B, which brought its stock price up to $3.65 and valuation to $302.56 million, with General Catalyst joining Kleiner Perkins and Lightspeed Venture Partners.19
Less than a year later, in May 2022, Glean reached unicorn status with its Series C, raising $101 million at a $9.67 stock price and an even $1 billion valuation. This round included investment from Sequoia Capital, alongside the aforementioned Series B investors.20
In February 2024, Glean more than doubled its valuation to $2.2 billion, raising $203.2 million for its Series D at a $17.63 stock price.21 This round was led by Kleiner Perkins and Lightspeed Venture Partners, while also including some existing investors and new ones such as Coatue, Capital One Ventures, Databricks Ventures and Workday Ventures.22
A few months later, in September 2024, the Glean Series E brought in another $265 million,23 co-led by Altimeter and DST Global, alongside several others such as Sapphire Ventures and SoftBank Vision Fund 2.24 This round brought Glean's stock price to $33.22 and its valuation to $4.6 billion.25
Most recently, Glean completed its Series F in June 2025, which raised $150 million and took its valuation all the way to $6.5 billion.26 This round was led by Wellington Management.27

Glean IPO outlook
As of May 2026, Glean has not publicly announced plans for an initial public offering (IPO). However, with $200 million in ARR and a $6.5 billion valuation from its Series F, the company has reached a scale where an IPO may be a reasonable possibility.
Glean's revenue growth trajectory and enterprise customer base could potentially support a public listing. Several factors could influence timing, including broader market conditions for tech IPOs, Glean's continued revenue growth and competitive dynamics in enterprise AI. Investors considering pre-IPO Glean stock should keep in mind that IPO timelines for private companies are inherently uncertain, and there is no guarantee that Glean will go public on any particular schedule.
How to buy Glean stock
As a private company, Glean's stock is not available for sale to the general public. However, accredited investors may be able to buy Glean stock through a private marketplace such as Forge, subject to availability.
Forge's technology and relationships may help facilitate trading private company shares in companies like Glean, along with other private market AI and enterprise software companies.
Who can invest in Glean pre-IPO?
Because U.S. regulations generally restrict the offer and sale of private company securities to accredited investors, investment in a non-public company like Glean is typically only available to such investors.
Some large accredited investors, such as venture capital (VC) funds and certain high-net-worth individuals, may be able to invest in Glean if selected to participate in primary funding rounds or strategic investment partnerships. Smaller accredited investors interested in buying may access Glean stock through a private stock marketplace like Forge, subject to the availability of shares.

Pre-IPO Glean stock is not for sale to the general public, but accredited investors may be able to buy shares of Glean through a private marketplace such as Forge for private market trading.
Registered investors with a verified profile may also explore Forge's active opportunities for companies similar to Glean in the AI or broader tech sectors.
Potential indirect exposure to Glean for non-accredited investors
At least for now, Glean has not announced IPO plans, so investment is generally limited to accredited investors. However, there are publicly available investment options that may provide exposure to broader trends in the enterprise AI or workplace productivity sectors, which could in turn impact companies like Glean.
Some examples include:
- Publicly traded enterprise software companies. Several publicly traded enterprise software companies are building AI capabilities that directly compete with or overlap with Glean. Microsoft, whose Copilot product is one of Glean's most prominent competitors, is embedded across Microsoft 365. Software providers like Salesforce and ServiceNow are also expanding AI search and agentic capabilities.29 These companies serve many of the same customers Glean targets, though their stocks are typically driven by their broader businesses rather than potentially being as dependent on enterprise AI performance like Glean.
- Publicly traded AI companies. Beyond the traditional enterprise software incumbents, there are publicly traded AI-focused companies that may have some correlation with Glean's category. Nvidia, for one, provides the underlying chips that power much of the AI sector. Exposure to Nvidia or similar semiconductor companies could provide access to potential AI sector growth that may also benefit Glean, too. Other types of AI software companies, such as Palantir, might also provide correlated exposure given thematic overlap with Glean in terms of companies investing in AI tools that help them get more out of their data. More broadly, companies like Oracle30 and Meta31 are investing heavily in AI research and enterprise AI products that could either complement or compete with Glean, depending on how the market evolves.
- Broader AI and enterprise tech funds. Retail investors might look for exposure through ETFs or mutual funds that hold a range of companies involved in AI and enterprise software. These funds may have varying degrees of overlap with Glean's specific market, and investors should review holdings to determine how well they fit with their investment goals and risk tolerance. General tech-heavy funds, such as those tracking the QQQ index, could also provide exposure to the broader tech sector that Glean often serves and/or partners with.
How to analyze Glean stock
Private companies generally do not face the same disclosure requirements as public companies, which can make analyzing private market stocks like Glean challenging. That said, Glean has publicly shared select financial and operational details through funding announcements and media reporting, though disclosure remains more limited than for public companies.
In February 2025, Glean announced that it hit $100 million in ARR in three years since launching, making it one of the fastest enterprise software startups to hit this mark.32 Toward the end of 2025, Glean then broke $200 million in ARR, which also kept it on pace as one of the fastest-growing enterprise software startups ever.33
Investors could look at this revenue data, alongside Glean's funding and valuation history plus its Forge Price, to determine how Glean's stock compares to similar private companies listed on Forge's private stock marketplace. This data could also be compared with public market competitors.
Still, even when looking at what Glean has disclosed and the real-time pricing insights on Forge, private market stocks are generally more opaque than public market ones. Analyzing Glean stock can be relatively subjective, as it can be when valuing other private market companies.
Potential risks of investing in pre-IPO Glean stock
While Glean's revenue growth has been notable, there are significant potential risks to consider:
- Entrenched competition. Glean faces a lot of competition, especially from tech giants like Microsoft (via Copilot) that arguably have the advantage of being entrenched within enterprises already.
- Competition from LLMs. Glean also faces competition from some of the LLM providers it leverages. For example, OpenAI and Anthropic34 are pushing further into enterprise markets with products that could directly compete with Glean's search and agent offerings.
- Valuation vs. revenue multiple. While growing quickly, a $6.5 billion valuation from its last primary funding round indicates certain investors are willing to pay a high revenue multiple. It remains to be seen how much Glean can meet those expectations.
- Private market limitations. As a private company, investing in Glean carries inherent risks including but not limited to the potential for loss of value, limited liquidity for exiting positions, less transparency into financials and other data compared with publicly traded stocks and other general risks entailed in any type of investment.
