About Fella Health

Fella Health is the telehealth clinic for men with obesity, backed by Y Combinator. With Fella, patients meet a board-certified obesity doctor to prescribe FDA-approved medications, while they undertake personalized health coaching through our app.

Obesity is the largest chronic disease in the US (>$100bn spent each year) and the traditional solution ("move more, eat less") only works long-term for ~10% of people. But obesity treatment is radically changing due to a new wave of medication options which are 2-3x more effective than previous options. In addition, only 10% of those using weight management services are men: all programs market to women, not tackling the stigma men feel around this.

Fella's founders are Luke & Richie. We studied together at Cambridge University.

Luke studied medicine and developed a patented AI approach to detecting cancer at a YC bio company, before moving to Microsoft Research. He did a masters in Computer Science after Cambridge.

Richie personally struggled with stress eating for 6 years. After Cambridge, he built and sold an AI company working with the UK government. He built a 10k-follower community around men's stress eating.
