Latest check 2026-11-13: 61 of 61 companies checked, from 38 public sources. - Category: [Partner management & ecosystems](https://www.usedby.ai/tools/category/partner-management.md) - Website: [partnerstack.com](https://partnerstack.com/) ## Customers Every line is a customer, at one of three proof levels: confirmed (a case study, a named quote, a press release, or the company's own public account of using the tool (its own site, or a post by one of its executives, VP or above)), observed (the vendor shows the company on its own pages) or signal (a job post shows the company's employees use the tool, the weakest proof). A line the company declared to usedby itself, or that it lists as a sub-processor on its own legal page, is marked declared. The first public proof is a relationship-level date, not an adoption date. Relationship labels describe the source's scope. They do not establish current contract, spend or company-wide deployment. The claim permalink identifies the usedby record; the primary source supports the relationship. These two links provide attribution for a summary. Evidence is selected, not exhaustive; missing evidence or a public archive does not establish that none exists. Relationship-level dates are not verified publication dates of the selected source. | Company | Industry | Proof | First public proof | Source | Relationship | Claim | |---|---|---|---|---|---|---| |
