About the Company

Name: Zinc

We believe in transparency for candidates and true respect for privacy in background checking.

📖 Our Story: we believe in a fairer, more transparent process. One which is quick, easy, and productive for every party. A process enabling candidates to own their data, and companies to access the unbiased insights they need.

⚡️ Zinc’s founding team have spent years in talent and HRTech. We saw a field plagued with inefficiency, prejudice and a lack of transparency. We first sought to solve the burden of referencing, then sought to tackle the broader category of background checking.

🚀 Our Mission: Change the way people prove their work identity.
