A line the company declared to usedby itself is marked declared. A signal is never a case study or a vendor listing. Strongest proof first. "Last check" is the later of the line's re-verification and its latest capture. | Tool | Company | Proof | Source | Last check | |---|---|---|---|---| | Harvey | [Bridgewater](https://www.usedby.ai/companies/bridgewater.md) | Confirmed | [harvey.ai](https://www.harvey.ai/customers/bridgewater), captured 2026-10-01 | 2026-10-24 | | Harvey | [KKR](https://www.usedby.ai/companies/kkr.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [Kleiner Perkins](https://www.usedby.ai/companies/kleiner-perkins.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-13 | 2026-10-13 | | Harvey | [DST Global](https://www.usedby.ai/companies/dst-global.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [Berkshire Partners](https://www.usedby.ai/companies/berkshire-partners.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [Hudson Bay Capital](https://www.usedby.ai/companies/hudson-bay-capital.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [PGGM](https://www.usedby.ai/companies/pggm.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [Imperial Capital](https://www.usedby.ai/companies/imperial-capital.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [Resource Capital Funds](https://www.usedby.ai/companies/resource-capital-funds.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [Terra Firma](https://www.usedby.ai/companies/terra-firma.md) | Observed | [harvey.ai](https://www.harvey.ai/customers) | Not dated | | Harvey | [Five Elms Capital](https://www.usedby.ai/companies/five-elms-capital.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Harvey | [IEQ Capital](https://www.usedby.ai/companies/ieq-capital.md) | Observed | [harvey.ai](https://www.harvey.ai/customers), captured 2026-10-24 | 2026-10-24 | | Norm AI | [Blackstone](https://www.usedby.ai/companies/blackstone.md) | Observed | [norm.ai](https://www.norm.ai/), captured 2026-10-16 | 2026-10-16 | | Norm AI | [Vanguard](https://www.usedby.ai/companies/vanguard.md) | Observed | [norm.ai](https://www.norm.ai/), captured 2026-10-16 | 2026-10-16 | | Norm AI | [Bain Capital](https://www.usedby.ai/companies/baincapital.md) | Observed | [norm.ai](https://www.norm.ai/), captured 2026-10-16 | 2026-10-16 | | Norm AI | [Bridgewater](https://www.usedby.ai/companies/bridgewater.md) | Observed | [norm.ai](https://www.norm.ai/), captured 2026-10-16 | 2026-10-16 | | Norm AI | [TIAA](https://www.usedby.ai/companies/tiaa.md) | Observed | [norm.ai](https://www.norm.ai/), captured 2026-10-16 | 2026-10-16 | | Legora | [S&P Global](https://www.usedby.ai/companies/s-p-global.md) | Observed | [legora.com](https://legora.com/), captured 2026-10-24 | 2026-10-24 | | Legora | [Crescenta](https://www.usedby.ai/companies/crescenta.md) | Observed | [legora.com](https://legora.com/customers), captured 2026-10-24 | 2026-10-24 | | Legora | [Twelve Capital](https://www.usedby.ai/companies/twelve-capital.md) | Observed | [legora.com](https://legora.com/customers), captured 2026-10-24 | 2026-10-24 | | Sirion | [Goldman Sachs](https://www.usedby.ai/companies/goldman-sachs.md) | Confirmed | [sirion.ai](https://www.sirion.ai/library/case-study/automating-document-processing-for-regulatory-reporting-and-compliance/), captured 2026-10-07 | 2026-10-19 | | Sirion | [Olayan](https://www.usedby.ai/companies/olayan.md) | Observed | [sirion.ai](https://www.sirion.ai/library/customer-stories/), captured 2026-10-19 | 2026-10-19 | | LegalOn | [Compass Diversified](https://www.usedby.ai/companies/compass-diversified.md) | Observed | [legalontech.com](https://www.legalontech.com/customers), captured 2026-10-18 | 2026-10-18 | | LegalOn | [Marex](https://www.usedby.ai/companies/marex.md) | Observed | [legalontech.com](https://www.legalontech.com/customers), captured 2026-10-18 | 2026-10-18 | | Spellbook | [Franklin Templeton](https://www.usedby.ai/companies/franklin-templeton.md) | Observed | [spellbook.com](https://spellbook.com/), captured 2026-10-19 | 2026-10-19 | ## Method Public customer lines of active Legal AI tools at companies classified in Investment & VC.
