The Predictive Index

The Predictive Index (PI) is a talent optimization platform that pairs 70+ years of behavioral science with software to help organizations hire, engage, and develop teams — behavioral and cognitive assessments, hiring and candidate screening, leadership development, employee engagement, and performance management. PI publishes a RESTful Integration API (on Azure API Management) that lets external systems such as ATS/HRIS platforms programmatically create candidates, send behavioral and cognitive assessments, retrieve jobs and results, and generate insight and coaching-guide reports — the same data that appears in the PI Portal software. Status-change notification webhooks push assessment completion events to listening systems. Backed by a $50M investment from General Catalyst.

The Predictive Index publishes 4 APIs on the APIs.io network, including Behavioral Assessments API, Candidates API, Employees API, and 1 more. Tagged areas include Company, Talent Optimization, HR, Human Resources, and Assessments.

The The Predictive Index catalog on APIs.io includes 1 event-driven AsyncAPI specification.

The Predictive Index’s developer surface includes documentation, API reference, getting-started guide, authentication, engineering blog, support, pricing, and 15 more developer resources.
