Fella Health

Fella Health (operating under fellahealth.com, legally AIOS Inc.) is an enterprise-grade telehealth clinic, specialized men's metabolic health engine, and medical weight management platform engineered to dismantle the severe social stigma, clinical fragmentation, and lifestyle friction preventing busy men from accessing sustainable obesity treatments. Founded in 2021 by Cambridge University alumni Richie Cartwright and Luke Harries under the institutional incubation of Y Combinator, the corporation revolutionized the consumer digital health sector by building a personalized, science-backed care delivery network tailored specifically for men. Moving past historical weight-loss paradigms—which relied on inefficient, low-compliance "willpower-only" routines that fail long-term for roughly 90 percent of patients—Fella Health natively unifies board-certified clinical obesity evaluations, continuous medical oversight, direct-to-home deliveries of advanced GLP-1 and GIP metabolic medications (such as semaglutide and tirzepatide), and continuous 1:1 behavioral health coaching. Underpinning its hyper-scale distribution architecture is ClinicOS, the company's proprietary, AI-driven clinical operating system designed to automate administrative workflows, optimize patient-clinician triage, and enable consumer brands to launch direct-to-patient healthcare channels seamlessly at scale. Backed by marquee institutional venture capital firms including Y Combinator, BrandProject, and Global Founders Capital, alongside prominent angel backers behind tech giants like Indeed and Alan, the cash-flow positive enterprise has scaled its multi-brand footprint across the United States and the United Kingdom. Serving over 50,000 active members and generating upwards of $100 million in annualized revenue, the organization continues to pioneer scalable consumer biotech access. Headquartered in Austin, Texas, with additional offices in San Francisco, California, the company operates via a highly distributed, remote-first global workspace. What distinguishes Fella Health is its strict, no-nonsense integration of clinical precision and psychological re-conditioning; by connecting high-availability programmatic telemedicine infrastructure with advanced endocrine and metabolic pharmacology, the corporation remains a definitive vanguard in the global fight against chronic metabolic disease and modern longevity optimization.
