WellTheory has raised $14 million in Series A funding led by General Catalyst, bringing total capital raised to $26.2 million. The round included participation from 7wire Ventures, Ingeborg Investments, Accel, Box Group, Leaps by Bayer, and Up2 Opportunity Fund.
The San Francisco-based company provides virtual care for autoimmune diseases through diet, lifestyle interventions, and care coordination with licensed registered dietitians and board-certified health coaches. WellTheory serves patients with conditions including rheumatoid arthritis, lupus, and multiple sclerosis.
Autoimmune disease affects more than 50 million Americans and represents a market valued at over $160 billion. The category has doubled over the past three decades and has become a major spending area for employers and health insurers as specialty drug costs increase.
“WellTheory is building the future of autoimmune care with a model that’s uniquely designed for today’s workforce,” said Ellen Rudolph, CEO and co-founder of WellTheory. “Employers are facing rising costs, while employees wait years for answers on their own health — a frustrating journey I experienced firsthand. By combining high-touch care with AI-enabled personalization, we’re addressing both parties, delivering a better quality of life for patients and measurable cost reductions for employers and payors.”
WellTheory has secured partnerships with Fortune 100 and 500 employers including Maven Clinic, Fortune Brands Innovations, and Dayforce, as well as health insurers including Sentara Health Plans and a top national insurer. Independent claims analyses show the platform reduces emergency room visits, imaging procedures, hospitalizations, and biologics utilization while saving thousands of dollars per patient annually.
“WellTheory is addressing the impact of autoimmune disease by recognizing the important role that diet and lifestyle can play in supporting patients,” said Candace Richardson, partner at General Catalyst, who is joining the company’s board. “The platform is demonstrating how this kind of support can be delivered at scale, and this is just the beginning. It is expanding to integrate medical treatment and medication management, creating a more comprehensive model designed to improve patient experiences and strengthen system sustainability.”
The company reported 10x year-over-year member growth and 5x revenue growth in the past year after launching commercially 18 months ago. WellTheory recently launched AI-powered tools including Care Hub and Care Scribe, which are deployed across its care operations.
“Employers and payers are urgently seeking solutions that improve outcomes while reducing costs. WellTheory’s AI-powered, whole-person model is proving it can do both,” said Tiffany Yu, Principal at 7wire Ventures. “We are impressed by the company’s ability to deliver meaningful savings for its partners today while also setting a new standard for a personalized, consumer-first experience.”
