Can Glean do what Amdahl does?

For retrieval, yes. For eval, no. Glean will index your Gong transcripts, your support tickets, and your CRM notes alongside everything else in your stack. If you ask it "what did customers say about pricing last week," it will pull passages. What it will not do is score a hero line, battle card claim, or outbound opener against won and lost deal language with citations. Glean is enterprise search. Amdahl is the GTM eval. The line is clean once you see it.

We already have Glean. Do we really need Amdahl?

If your GTM team generates messaging, content, or outbound with AI and needs to know whether it holds against customers, then yes. Glean will not do that job. Glean is a retrieval tool. Retrieval is not an eval. Teams that try to force Glean into this job end up with a search bar over their Gong library. Keep Glean for enterprise search. Add Amdahl for the eval.

Does Amdahl integrate with Glean?

Amdahl has its own ingest from Gong, Fathom, HubSpot, Salesforce, Zendesk, and Slack customer channels, and its own MCP server for agent access. Glean can index Amdahl-produced artifacts alongside the rest of your internal knowledge so they show up in company-wide search. The reverse direction, using Glean as an ingest source for Amdahl, is not the pattern we recommend, because Amdahl runs enrichment and scoring directly on the raw conversation data. The two systems sit side by side rather than nested inside each other.

Will Glean eventually build what Amdahl does?

Glean's roadmap is enterprise-wide search and agentic work across every department. Going deep on one vertical workflow, GTM draft evals with conversation-specific classifiers and scoring, is a different product strategy. Horizontal platforms rarely ship the depth a vertical eval needs. The safer assumption is that Glean stays a horizontal search and assistant layer, and vertical systems like Amdahl own the draft-vs-customer-evidence job for GTM. The two categories coexist.

Our Gong content is in Glean. Why do we need a second system on the same data?

Because indexing a transcript for search is not the same as running an eval over every utterance. Glean treats a Gong call the way it treats a Confluence page, a retrievable document. Amdahl treats a Gong call as structured conversation evidence. Every utterance gets speaker attribution, sentiment, persona inference, and competitive mention classification. Drafts get scored. Outputs get citations. None of that happens when a call transcript sits in an enterprise search index. The data is the same. The product doing the work is different.

Who is the buyer for Amdahl vs Glean inside our company?

Glean is almost always bought by IT, KM, or the CIO's office, because the value is horizontal and the deployment is company-wide. Amdahl is bought by the GTM Engineer, Head of Product Marketing, or a founder running GTM directly, because the value is the eval and the deployment is the GTM org. The buying committees rarely overlap. That is part of why these two tools coexist without a budget fight.

Amdahl vs Glean

Glean retrieves what your company already wrote. Amdahl evals GTM drafts against what customers said.

Glean is the enterprise AI search layer. Connectors into Slack, Drive, Notion, GitHub, Jira, Confluence, your CRM. Ask a question, Glean finds the document, the thread, the ticket. For "find what someone in this company already wrote," it is hard to beat.

Amdahl is not enterprise search. Amdahl is the eval layer for GTM Engineers. Score messaging, content, and outbound against customer conversations, with citations back to the call or ticket. The job is not retrieval. The job is whether the draft holds up.

You can index transcripts in Glean. Glean will retrieve passages. It will not score a hero line, battle card claim, or outbound opener against won and lost deal language. Glean finds. Amdahl evals.

The one sentence version

Glean retrieves docs. Amdahl evals drafts.

One finds what exists. The other scores what you are about to ship.

When to buy Amdahl

01
You need to score GTM drafts against real buyer evidence
02
Your GTM team lives or dies on whether AI-generated copy holds
03
You want persona, sentiment, and deal-stage classification on every utterance
04
You want scores with citations, not search results

When to buy Glean

01
You need enterprise-wide search across Slack, Drive, Notion, Confluence, GitHub
02
You are deploying a work assistant for every employee, not just GTM
03
IT, KM, or the CIO's office owns the budget and the rollout
04
The job is retrieval and company-wide Q&A, not GTM evals

Where they split

01
GTM engineer at a Series B B2B SaaS
You have 300 Gong calls you have not scored anything against. Sales is shipping AI-written messaging that contradicts the website. You need to know whether a hero line or battle card holds against lost enterprise deals, which persona is driving the objections, and which exact quotes back each mark. Glean can retrieve a Gong transcript if you already know which call to ask about. It cannot score the draft. Amdahl does the eval. Glean was not built for it.
02
Enterprise knowledge access for a 5,000-person company
You run IT or knowledge management at a mid-market or enterprise company. Employees waste hours a week searching Slack, Drive, Notion, Confluence, and Jira for things that were already written. You want every employee to be able to ask "what is our policy on X" or "who owns project Y" and get a cited answer from the company's own knowledge. You need SSO, permission-aware retrieval, and a Personal Graph per employee. This is Glean. It is the category-defining product for this job, and Amdahl is not trying to compete for it.
03
Series C company that already runs Glean
You have Glean deployed. Engineering, support, and ops use it every day to search internal docs. Your GTM team also uses it to find old decks. That is working. What Glean does not do is score GTM drafts against conversation data. You add Amdahl for the eval: paste the draft, get a score, gaps, and citations. Glean stays the enterprise search layer. Amdahl is the eval layer. They do not compete.
