Quotes
Licensed real-world data: We purchase data directly from employers—data that reflects how real organizations actually operate.
Expert or contractor-created: The experts train large language models using their academic expertise—developing domain-specific prompts, assessing responses, and judging output quality across disciplines from law and finance to virology and music theory.
Stated confidentiality practices: Company data is de-identified and handled under contract; access is limited to authorized teams, and datasets are delivered to labs under confidentiality without identifying partner companies. Handshake also states that employees are screened, sign confidentiality agreements, and receive least-privilege access.
