Function is a model of improvement.

What’s happening: The preventative health platform raised $298M at a $2.5B valuation and introduced Medical Intelligence Labs, a medically informed AI health copilot.

In form. Leading a healthcare paradigm shift, Function rapidly scaled its diagnostics membership—completing 50M tests to date—while partnering with wellness insiders, Equinox gyms, the NBA, and more.

Drawing baseline biannual checks for heart, hormonal, organ, and immune health, its acquisition of Ezra integrated full-body rapid MRIs and CTs for cancers, endometriosis, and stroke.

Thread the needle. Now incorporating wearables, health records, and clinical research, Function’s new MI Labs creates a bridge between wellness and medicine, leveraging AI to translate complex inputs into actionable lifestyle interventions.

Version control. From WHOOP and Oura to Superpower to Parsley, bloodwork is a default in the pursuit of a Personal Health OS, with labs operators Quest and Labcorp powering the underlying infrastructure.

A work in progress, companies are racing to turn data into health outcomes. As Function taps AI for one-to-many care, Hims just launched labs to verticalize treatments and personalize plans.

Looking ahead: With capital to scale, a star Doctor x Founder on board, and momentum to normalize head-to-toe screening as the new annual physical, Function will push its OS as the next evolution of alternative medicine.
