WellTheory raises US$14m to scale AI-supported virtual care for autoimmune disease

Virtual care provider WellTheory has raised US$14m in Series A funding to expand its autoimmune care platform, bringing the company’s total funding to US$26.2m.

The round was led by General Catalyst, with participation from new and existing backers including 7wire Ventures, Box Group, Ingeborg Investments, Up2 Opportunity Fund and Accel. The investment will support commercial growth, expansion into employer and payer channels, and acceleration of the company’s AI capabilities.

Founded in 2022, WellTheory delivers virtual, multidisciplinary care for people living with a wide range of autoimmune conditions. Its programmes support patients with lupus, fibromyalgia, Crohn’s disease, multiple sclerosis, coeliac disease, hypothyroidism, rheumatoid arthritis, Graves’ disease and other immune-mediated disorders that are often complex and poorly served by traditional care pathways.

Members are matched with care teams that can include health coaches, nutrition specialists and clinicians, with a focus on lifestyle, nutrition, symptom tracking and root-cause management alongside conventional treatment. The model aims to offer more continuous, personalised support than the episodic appointments many patients currently experience.

“As someone who’s lived with autoimmune disease, I know how broken and impersonal the system can feel,” said Ellen Rudolph, CEO and co-founder of WellTheory. “We’re using AI to change that — not to replace care, but to deepen it. By combining technology with empathy, we’re making it possible to deliver personalised, root-cause care to millions who’ve spent too long feeling unseen.”

WellTheory is positioning its platform as a partner for health plans and employers looking to manage the high cost and complexity of autoimmune conditions.

In June, the company announced its first payer partnership with Sentara Health, a not-for-profit integrated health system. Under that agreement, nearly one million members of Sentara Health Plans in Virginia and Florida can access a WellTheory care team for 12 months of structured autoimmune support.

The business is also betting heavily on AI to streamline workflows and make its model scalable. Earlier this year, WellTheory unveiled two in-house tools, Care Scribe and Care Hub. Care Scribe is an AI assistant that supports care teams by transcribing consultations, drafting follow-up notes and helping to create personalised care plans. Care Hub aggregates member data, lab results and session history into a single workspace, supporting pre-visit preparation, post-visit actions and automated compliance tracking.

Alongside core autoimmune programmes, WellTheory is moving into adjacent areas of women’s health that frequently overlap with immune and inflammatory conditions. In December, the company launched a women’s health programme focused on hormonal conditions such as endometriosis, menopause and polycystic ovary syndrome (PCOS).

The virtual care provider is also building out its employer channel. In 2023, it announced its first employer partnership with Maven Clinic, giving employees of the virtual women’s and family health company access to nutrition and lifestyle coaching from WellTheory.

With fresh capital in place, WellTheory plans to deepen its offer for payers and employers, scale its AI tooling and broaden access to condition-specific programmes.

The company is betting that combining human care teams with AI-enabled workflows can deliver more responsive, integrated support for people living with autoimmune disease — a patient population that has historically struggled to find joined-up, personalised care.
