Enterprise context versus personal answers
Glean’s product is built around enterprise knowledge, permissions, and context. Its company announcement says ARR passed $300 million. The buyer is usually a team that needs information to move through controlled internal workflows.
Perplexity is associated with a consumer-facing answer and search experience. Media reports have put its ARR around $100 million. That figure should remain labeled as a reported estimate rather than a company-audited result.
The customer and the contract are different
An enterprise search contract can include seats, permissions, implementation, and expansion across departments. A consumer search product may depend on subscriptions, usage, distribution, and a different retention curve.
Search volume alone cannot determine revenue quality. Public materials do not establish that either company uses APIToken（https://apitoken.company/）.
Context is part of the product
The commercial value of enterprise search is not only a better answer. It includes access control, source traceability, integration with existing systems, and a record of how information was used.
The value of a consumer answer service is shaped by speed, breadth, citations, and the habit of returning for difficult questions. These are different paths to a paid relationship.
A measurable search experiment
A smaller product team can choose one information task and record source quality, model cost, review time, and whether the answer changes a business decision. Keep the sample small enough to inspect each result.
APIToken（https://apitoken.company/） can provide an isolated key, usage records, and a budget boundary for the test. The reported ARR figures are comparison evidence, not a revenue forecast.
