The short answer
Glean and Claude Enterprise are two different purchases that happen to answer the same question. Glean builds a persistent index of your company's apps and sells it by quote only: it publishes no price, and Vendr reports a median of $98,890 a year across 174 purchases. Claude Enterprise publishes its price, $20 per seat per month billed annually plus every token at API rates, with a 20 seat minimum, and reaches your data through connectors that Anthropic says query sources live with "No external indexing". If your problem is that nobody can find anything, you are buying an index. If it is that people need a strong assistant, you are buying seats.
Searchers typing "glean vs claude" are usually halfway through a budget conversation. Someone on the leadership team has used Claude and liked it, someone in IT has sat through a Glean demo and liked that too, and now there is one line in the plan and two vendors fighting for it. The comparisons ranking for this question do not help much. One is a review aggregator with star ratings, and one is Glean's own comparison page, which is exactly as neutral as you would expect.
This article compares the two on the three things that end up in the contract: what each one costs, how each one reaches your company's data, and what each vendor claims about the other that does not hold up. Glean figures come from Glean's own site and docs plus two procurement data sources, labeled as secondary every time. Claude figures come from claude.com/pricing and Anthropic's help center.
How much does Glean cost?
Glean does not publish a price. Its pricing URL now redirects to the homepage, and every deal is quoted by sales. The best available numbers are secondary. Vendr reports that the median buyer pays $98,890 a year, with a range of $29,880 to $208,897, based on 174 purchases. SpendHound, drawing on 42 teams, reports an average of $142,019 a year for smaller companies and $259,933 for enterprises.
Two more secondary details matter for a mid-sized buyer. Vendr says Glean "typically requires minimum user commitments, often starting around 100 to 250 users for enterprise deployments", which Glean itself does not publish. SpendHound reports its small-company average rose 103.57 percent year over year. If you are a 60-person company, ask early whether a minimum applies, because it changes the whole comparison. The full breakdown is on our Glean pricing page.
How much does Claude Enterprise cost?
Claude Enterprise is $20 per seat per month, billed annually, and the seat includes no usage. Anthropic's billing article is blunt about it: the seat fee "doesn't include any usage. Every token your team consumes is billed separately at standard API rates." Enterprise organizations have a 20 seat minimum, and seats cannot be removed during the annual term. Reductions only take effect at renewal.
Claude Team is the other option: $20 per standard seat billed annually, $25 monthly, for teams of 2 to 150, with usage included inside published limits. Team lacks SCIM, audit logs, the Compliance API and the HIPAA-ready offering, which is usually what pushes a company to Enterprise. Two billing details catch finance teams out. On self-serve Enterprise, usage is prepaid in credits and "When the balance hits zero, usage stops for the whole organization until an Owner purchases more." And turning on US-only inference bills usage at 1.1 times API rates. Everything else is on our Claude Enterprise pricing page.
Glean vs Claude Enterprise side by side
| Question | Glean | Claude Enterprise |
|---|---|---|
| Published price | None. Quote only | $20 per seat per month billed annually, plus usage at API rates |
| What companies report paying | Median $98,890 a year (Vendr, secondary) | Seats are fixed, usage varies with model and task, so there is no single figure |
| Minimum commitment | Often 100 to 250 users (Vendr, secondary, not published by Glean) | 20 seats, published. No seat removals mid term |
| How it reaches your data | A persistent index. Glean claims "275+" permission-aware apps | Connectors queried live over MCP. Anthropic: "No external indexing" |
| Who connects the apps | Admins connect sources for the company | Admin enables, then "Each person still needs to authenticate individually", with an Okta-based exception for some apps |
| Models | OpenAI, Google and Anthropic models, per Glean's admin docs | Anthropic models only |
| Strongest at | Finding things across many apps for a whole company | Writing, analysis, code and agent work for each person |
Read the price rows carefully. Claude looks cheaper because it publishes a number, and at 200 people the seats alone are $48,000 a year against a Glean median near $99,000. But the Claude figure excludes every token, and heavy Enterprise users on the top models can make usage the larger line. The Glean figure is a median of negotiated deals of unknown size. Neither number is your bill until someone models your headcount and usage.
Glean vs Claude connectors: index or live query?
This is the real difference, and it matters more than price. Glean crawls your connected apps into its own index ahead of time, so a question is answered from content that has already been collected and ranked. Claude does the opposite. Anthropic's enterprise search article states that results are generated by making MCP calls and that "No data from connected services are indexed in our systems for serving queries."
That design has a consequence nobody on the Claude side advertises: coverage depends on each person. Anthropic's connector article says enabling a connector "doesn't automatically grant anyone access. Each person still needs to authenticate individually before they can use it." For 300 people and five apps, that is 1,500 separate sign-ins before the assistant can see everything the company knows.
Anthropic has started closing that gap, and it is fair to say so. Enterprise-managed authorization lets an admin "authorize a connector once for your entire organization", but only through Okta for now, and only for Asana, Atlassian, Canva, Datadog, Figma, Granola, Linear, Notion, Slack and Supabase. Google Drive, Microsoft 365 and GitHub are not on that list. Anthropic's own pages also disagree on its status: one article calls it generally available for Team and Enterprise, another still calls it a beta. Microsoft 365 separately needs one-time consent from an Entra Global Administrator.
On permissions, give Claude credit. Because each person signs in with their own credentials, Claude only ever sees what that person could already open. Glean's comparison page suggests Claude's enforcement "may be data-source-level rather than object/record-level", but a connector acting as the individual user inherits that user's access in the source app. The practical risk with Claude is not oversharing. It is missing answers because nobody connected the app that held them. How query-time permission checks should work is covered in permission-aware AI search.
What Glean claims about Claude, checked
Glean's marketing leans on a study stating its results are preferred "1.6x more than Claude". Before that number goes into a business case, know how it was produced. Glean ran it, and six Glean employees wrote it up. It used about 280 queries mined from Glean's own internal deployment rather than customer data, weighted toward multi-source questions. Four graders scored it blind, and Glean's own AI quality team then cross-checked their results. The body of the post puts the edge at 1.9x on correctness, counted only when graders had a preference. Latency and cost were not measured. It is a reasonable internal benchmark and a weak basis for a purchase.
One claim is contradicted outright. Glean's comparison page says "Cowork activity is excluded from audit logs and compliance APIs." Anthropic's help center says Cowork activity through Claude, Claude Desktop and Claude Mobile "is captured in the Compliance API", and that Enterprise admins can retrieve local session history through it. Anthropic's current documentation wins that one. Glean also counts its own reach differently on different pages: 275+ apps on the comparison page, 100+ native connectors on another, and 35+ versus 40+ supported models.
Can you use Glean and Claude together?
Yes, and plenty of companies will end up there. Glean publishes a remote MCP server listed in Claude's connector directory, announced in public beta on September 4, 2025, with a setup guide for Claude Desktop on Team and Enterprise. Claude then asks Glean's index instead of querying each app itself, which fixes the per-person coverage problem.
The catch is that you pay for both. Glean's MCP documentation says the feature "is subject to usage-based pricing and these supplemental FlexCredit terms", so you carry a Glean contract, a Glean usage meter, Claude seats and Claude tokens at the same time. If you would rather not wire and maintain that stack yourselves, you can hire a developer who builds and runs AI integrations for the setup, but budget for the ongoing meters either way.
Which should you buy?
Buy Claude Enterprise if the goal is making each person more productive at writing, analysis and code, your team is at least 20 people, and you can live with usage-based billing. Most of its value does not depend on company search at all.
Buy Glean if the goal is finding information across dozens of apps for a large company, you have the budget for a quoted six-figure contract, and you can meet a user minimum that may start in the hundreds. Compare it against the rest of the field first on Glean alternatives.
Consider a dedicated search product if the complaint is simply that people cannot find answers across Drive, Slack, Notion, Confluence, Gmail, Jira and Salesforce, and neither a six-figure quote nor 1,500 individual sign-ins fits. InSearch connects those sources once, centrally, enforces each source's permissions per person at query time, and returns one written answer with citations. It is published at $20 per user per month on Team, $32 on Business and $49 on Scale, billed annually, on our pricing page. It is also smaller than either vendor, holds no SOC 2 attestation today, and does not write code or run agents. If those matter, this is not your tool.
Frequently asked questions
Is Glean better than Claude?
For company-wide search across many apps, Glean is built for the job and Claude is not: Glean indexes sources ahead of time for everyone, while Claude queries connectors live for each person who has signed in. For writing, analysis and coding, Claude is the stronger product. Most buyers are really choosing which problem to fund first.
Does Glean work with Claude?
Yes. Glean offers a remote MCP server that appears in Claude's connector directory, with a setup guide for Claude Desktop on Team and Enterprise plans. Claude can then query Glean's index directly. Glean bills that access under usage-based FlexCredit terms, so it adds a meter on top of both subscriptions.
Does Claude Enterprise index company data?
No. Anthropic states that enterprise search results come from MCP calls to connected services and that no data from those services is indexed in its systems to serve queries. Each person authenticates their own connectors, except for a short list of apps that can be authorized once through Okta.
Is Claude Enterprise cheaper than Glean?
On seats, usually yes: 200 Claude Enterprise seats cost $48,000 a year, while Vendr puts Glean's median contract at $98,890. But Claude seats include no usage, so tokens are billed on top at API rates, and the Glean figure is a secondary median. Model your own usage before comparing. The same seat arithmetic against OpenAI is in Claude vs ChatGPT for business.
If Google and Microsoft are also on your shortlist, Glean vs Gemini Enterprise vs Copilot compares Glean against both, and Anthropic's agent product and its admin defaults are covered in Claude Cowork pricing and admin controls.
