About Function & Ezra

Function Health was founded with a singular focus: empower you to live 100 healthy years. We're doing that by using the best available technology to ensure people don't suffer or die a preventable death. Function has been recognized as one of Fast Company's Most Innovative Companies of 2024 and is venture-backed by Andreessen Horowitz (a16z). Hundreds of thousands of members have joined Function to take control of their health.

In 2024, Function acquired Ezra, the leading provider of full-body MRI screening for early cancer detection. Ezra pioneered accessible, AI-enhanced MRI imaging to help people catch cancer and other diseases at their earliest, most treatable stages. By bringing Ezra into Function's ecosystem, we're combining world-class diagnostics with advanced lab testing and cutting-edge technology - creating the most comprehensive preventive health platform on the market.

Our Mission at Ezra

Our mission at Ezra is to detect cancer early for everyone in the world. We offer a direct-to-consumer cancer screening service that leverages MRI and Artificial Intelligence to make cancer screening fast, accurate, and affordable. We are fully operational in multiple states such as New York, California, and Florida with an MRI-based full-body program covering 13 organs.

We believe in empowering people to be proactive with their health decisions. Our members sign up for an Ezra, visit a partner imaging center to get an MRI scan, and receive a comprehensive screening report within 10 business days.
