Health & Wellness Startups funded by Y Combinator (YC) 2026

Founded in 2014, Bellabeat is a data-centered wellness femtech company behind some of the most fashionably designed tech-powered wellness products and one of the fastest-growing wellness subscription services for women. Throughout the years, Bellabeat built the go-to wellness brand with a compelling ecosystem of solutions and services focused on women’s health. The success of the Leaf and Ivy wearables enabled the brand to expand to international markets and kickstart industry discussions on the importance of innovating in the design and development of tech products. Today, Bellabeat is leading the market shift with hyper-personalized holistic wellness offerings aligned with a women’s menstrual cycle.

Juno is an AI personal health assistant for the 1B+ people living with chronic illness. Juno builds a longitudinal health profile from conversations, biometrics, and medical history to identify patterns behind symptoms and provide tailored guidance. Isaac and Marshall started building Juno after growing up with chronic conditions and spending years trying to understand their symptoms. Like millions of others, they waited months for appointments and struggled to explain complex medical history in 15 minutes. As a result, key signals are missed, contributing to an average diagnosis time of 7.6 years. Even after receiving a diagnosis, patients are often left without a clear treatment plan and have to manage their condition alone. Many use AI chatbots for support, but without context on their medical history or symptom progression, they receive generic advice that is rarely actionable. Juno solves this by building a continuous, structured health profile for each user and connecting this fragmented health information. We spent the last year conducting research at Oxford and UCL to build our proprietary engagement layer for daily conversations, allowing Juno to ask the right questions at the right time and understand each user's health better than anyone else ever could. We launched in October and are already at $600k in annual run rate, supporting 50,000+ patients globally. We’re building a future where everyone has a private clinical specialist in their pocket, 24/7.

We know how to improve cancer outcomes by 8x-10x: you catch it early. MRI is the most robust and powerful cancer-detection tool in the world, yet systems cost millions to purchase, take months to install, and require high levels of technical skill to operate.

No equipment to buy, no infrastructure needed. For a flat per-scan fee, any medical site can offer MRI cancer screening. Starting with prostate cancer. Then everything else.

Nori is a concierge-level AI health coach in your pocket. It takes all of your health data—Apple Health, medical records, wearables, everything—and boils it down into a personalized daily plan.

I started getting more deep sleep, my resting HR dropped to 43, my recovery improved.”—Jen, Nori user"

Play Health is building a perimenopause care platform to provide women and their providers with the tools they need to relieve symptoms fast. It is led by technical, second-time, YC-backed founders Andrea Mazzocchi, PhD and Ian Miller, with an exit and a unicorn between them. Over 30 million women in the U.S. are experiencing perimenopause symptoms, spending an estimated $15B+ annually on symptom management. Despite this most only receive generic solutions and struggle to find effective symptom relief. We're bringing evidence-based perimenopause care to women through partnerships with medical practices and employer and health benefits programs. Our platform integrates personalized symptom, medication, and lifestyle data to generate AI-powered insights and clinical protocols, enabling providers to deliver specialized care. Every clinical interaction enriches our longitudinal dataset allowing us to create better outcomes for patients, deeper insights for providers, and expand into women’s health broadly. This also enables us to partner with pharma and biotech companies developing therapeutics and diagnostics for women's health.
