What Sama does
Sama was founded in 2008 as the nonprofit Samasource by Leila Janah and relaunched as a for-profit Certified B Corporation in 2019. It provides managed annotation, validation and model evaluation for computer vision and generative AI, delivered by full-time employees in East African delivery centers rather than an open crowd.
It names customers including Google, Microsoft, Ford, GM and Walmart, and reports a 98–99% first-batch client acceptance rate (company-reported). Its employment model — living-wage jobs in underserved communities — is independently certified through B Corp.
Strengths
- Full-time in-house workforce, not a rotating crowd
- Certified B Corp with third-party-audited impact claims
- Long enterprise track record (founded 2008)
Considerations
- No published pricing
- Widely reported litigation over Kenya content-moderation working conditions (2021 onward) — buyers running sensitive-content programs should ask about current welfare and exposure controls
- GenAI/LLM data lines are newer than its CV core
