Company profile

researched Aug 2026

Nourish operates a virtual care platform that connects patients with Registered Dietitians (RDs) for telehealth nutrition counseling, with care billed through insurance. The company positions nutrition as a first-line treatment for nutrition-related chronic and cardiometabolic conditions such as obesity, diabetes, heart disease, gastrointestinal conditions and eating disorders, and states that 94% of its patients pay $0 out of pocket. Its dietitians are in network with hundreds of insurance policies across all 50 states, including Medicare, Medicaid and national commercial payers such as Aetna, Anthem, Blue Cross Blue Shield, Cigna and UnitedHealthcare.

The service pairs recurring virtual dietitian appointments (conducted over Zoom) with a companion mobile app used between sessions. App features include photo-based meal and macro tracking, goal setting and progress tracking, messaging with the dietitian, session summaries and curated content, wearable and lab integrations, access to lab work at local clinics, and a 24/7 AI assistant. Dietitians are supported by an AI copilot that automates note-taking, surfaces clinical insights and reduces administrative work. The company also markets to employers and health plans, offering dietitian-led metabolic care for high-acuity members, supporting patients both on and off GLP-1 medications, and describes a care model spanning Registered Dietitians, therapists, and MDs/NPs alongside devices, labs and medical records.

A Clinical Advisory Board of physicians and researchers advises on care protocols and clinical standards; members listed include Dr. Ajay Haryani, Dr. Amanda Powell, Dr. Monica Berner and Dr. Dariush Mozaffarian, director of the Food is Medicine Institute at Tufts University.

Founding story

Nourish was founded by three close friends — Aidan Dewar, Sam Perkins and Stephanie Liu — who experienced the effects of food as medicine firsthand while working with a registered dietitian to address their own chronic conditions. The Series B announcement in April 2025 described the company as having been founded just over three years earlier.

Business model

Nourish delivers telehealth nutrition counseling reimbursed by insurance, contracting in-network with commercial, Medicare and Medicaid plans so that most patients pay only a copay or nothing. It employs its dietitian workforce as W-2 staff rather than contractors, and sells to health plans and employers on a cost-reduction thesis, citing modeled per-member-per-year savings and projected ROI. The company has also announced a clinical outcomes model tying fees to performance for dietitian-led metabolic care.

Revenue is generated from insurance reimbursement for dietitian visits under in-network payer contracts, complemented by health plan and employer partnerships; an outcomes-based fee arrangement tied to clinical performance has also been announced.

Traction

Company materials report more than 500,000 people helped by Nourish dietitians, over 3,000 W-2 registered dietitians at the time of the April 2025 Series B and more than 10,000 providers on later pages, availability in all 50 states, and partnerships with national commercial, Medicare and Medicaid plans covering hundreds of millions of lives. Reported 12-month outcomes include 8% average weight loss for patients not on GLP-1s, a 1.3 average reduction in A1C, a 27 mg/dL average reduction in LDL cholesterol and a 21 mmHg average reduction in systolic blood pressure. Health plan materials state 89% of members have at least one chronic condition, 61% have two or more, average medical spend per member of $16,000, projected 3.1x ROI and more than $2,000 in PMPY savings.

Latest developments

In May 2026 Nourish announced a $100 million Series C to reverse chronic disease with an AI-native metabolic clinic, alongside the introduction of a new brand, The Bloom. In June 2026 it announced a clinical outcomes model tying fees to performance, described as the first outcomes-based approach for dietitian-led metabolic care. The company has also published data showing patients completing six or more dietitian appointments achieve 2.3x greater weight loss, and has released an AI tools suite for patients and providers alongside plans to expand its care model with physicians.

Market position

The company describes itself as the leading provider of nutrition counseling in the United States and states it operates the largest registered dietitian network in the country, reporting over 3,000 W-2 RDs at the time of its Series B and more than 10,000 providers on later company pages. It was named to Fierce Healthcare's Fierce 15 of 2025.

Differentiators cited include insurance coverage with 94% of patients paying nothing out of pocket, nationwide availability across all 50 states, an employed W-2 dietitian network described as the largest in the country, integration of AI tooling for both patients and providers, and published clinical outcomes data — including 33% greater weight loss for patients on GLP-1s when paired with a Nourish dietitian and 2.3x greater weight loss for patients completing six or more appointments.

Technology

The platform integrates patients, dietitians and payers in a single virtual care system. Patient-facing technology includes an app with photo-based macro tracking, appointment scheduling and Zoom-based visits, messaging, goal tracking, lab result access and analysis, wearable integrations, and a 24/7 AI assistant. Provider-facing technology includes an AI copilot that automates clinical note-taking and surfaces insights. The company describes its newer direction as an AI-native metabolic clinic combining devices, labs and medical records with human clinicians.

Go-to-market

Nourish acquires patients directly through its website and consumer advertising with upfront insurance eligibility checks, through clinician referrals, and through partnerships with other healthcare companies. It also contracts with health plans and employers, and recruits dietitians directly via a "Become a dietitian" channel. Partnerships announced include Tia, Wisp, ModifyHealth and Future.

Patients with nutrition-related and cardiometabolic conditions — including obesity and weight management, diabetes and prediabetes, high cholesterol, hypertension, GI conditions such as IBS and Crohn's disease, celiac disease, eating disorders, fertility, menopause and hypothyroidism — as well as patients on GLP-1 medications. On the enterprise side, buyers are health plans and employers; referring physicians are an additional channel.

Geography

United States only; services are available in all 50 states via telehealth. The Series B announcement was issued from New York, NY.

History

Following its founding, Nourish raised a $35 million Series A led by Index Ventures in 2024 to expand access to registered dietitians. In April 2025 it announced a $70 million Series B led by J.P. Morgan Private Capital's Growth Equity Partners, bringing total funding to $115 million and, per press coverage, valuing the company at over $1 billion. Subsequent company milestones include the Fierce 15 of 2025 recognition, publication of its first annual impact report in February 2026, a $100 million Series C announced in May 2026 to build an AI-native metabolic clinic, a new brand called The Bloom introduced the same month, and an outcomes-based clinical fee model announced in June 2026.
