Calibrate

Subscription-based health-tech for metabolic weight loss

Overview

Calibrate focuses on sustainable weight loss by improving metabolic health rather than traditional dieting. It delivers a subscription-based program, commonly covered by employers, combining incremental habit changes with GLP-1 medication that targets biology to reduce inflammation, regulate digestion, enhance metabolic function, and lower cardiovascular risk. The program reports real-world results of about 15% sustained weight loss, distinguishing it from typical clinical trial claims. Clients are primarily corporations seeking employee wellness benefits, though individuals can subscribe too. The company offers a money-back guarantee if promised results aren’t achieved. Overall, Calibrate aims to help people lose weight and improve metabolic health in a practical, maintainable way, scaling through employer-based wellness programs.

Calibrate doubles client base, nears profitability with shift to enterprise obesity management

Calibrate, a digital obesity management platform, has completed its transition from direct-to-consumer to an enterprise-focused model, more than doubling its client base over the past year. The shift positions the company to achieve profitability for the first time in its history. The move responds to growing employer demand for weight management solutions as organisations grapple with rising costs and sustainability concerns around GLP-1 medications. Enterprise adoption now represents approximately 90% of Calibrate's business, with clients ranging from several thousand to several hundred thousand covered lives. Since launching over five years ago, more than 100,000 members have used Calibrate's integrated clinical care and coaching platform. The company has assembled a new leadership team to support its next growth phase, including CEO Rob Rebak and executives across operations, medical, commercial and finance functions.
