What knownwell does

knownwell is a hybrid weight-inclusive primary care and metabolic health company founded in January 2023 by Brooke Boyarsky Pratt and Dr. Angela Fitch, headquartered in Needham, Massachusetts. The company delivers in-person care through clinics in Atlanta, Boston, Chicago, and Dallas (with New York City announced) and virtual care nationwide via its own telehealth platform and a partnership with Eli Lilly's LillyDirect digital healthcare platform, reaching patients in all 50 states. Services span weight management including GLP-1 medication prescribing and management, comprehensive primary care, nutrition counseling, health coaching, body composition testing, remote patient monitoring, and a specialized adolescent obesity program (knownwell for Teens). Care is provided through independent practitioners operating under Seen Medical Group.

The technology stack combines a web platform with iOS and Android patient applications, athenahealth EHR integration, remote patient monitoring, and the ObesityRx AI-powered obesity management platform acquired from Alfie Health in June 2024, which provides clinical decision support for metabolic treatment planning. The patient mobile application supports visit management, secure messaging, lab results viewing, virtual visit participation, and medication renewal requests. The company published an inaugural Clinical Outcomes Report covering 1,807 real-world patients (Feb 2023–Feb 2025), reporting 15.9% average weight loss with 97% durability at 12 months and 50% lower lean-mass loss versus published GLP-1 trial benchmarks.

Revenue is generated through insurance-billed and self-pay consultations, GLP-1 and other weight management medication prescriptions (including through LillyDirect), and ancillary services, with no membership or sign-up fees. The company has raised over $50M cumulatively across a $4.5M seed led by Flare Capital Partners (Jan 2023), a $20M Series A led by Andreessen Horowitz (Dec 2023), and a $25M strategic financing led by CVS Health Ventures (Oct 2025). Backed by Flare Capital, A16Z, CVS Health Ventures, Flybridge, Oxeon Partners, Intermountain Ventures, and MassMutual Catalyst Fund, knownwell is positioning for value-based obesity contracts with payers and health systems alongside its direct-to-consumer model.

Partnerships

Three partnerships are on record, tiered core and minor.

• LillyDirect (Eli Lilly)coreStrategic or Co-development Partner · 3 April 2025Knownwell was announced as a care provider on Eli Lilly's LillyDirect digital healthcare platform in April 2025.

Direct peers

• Ro: Ro operates a direct-to-consumer telehealth platform that includes a robust weight management program featuring GLP-1 prescribing and ongoing clinical care. It is one of the most well-capitalized and highest-visibility competitors in the obesity telehealth category, directly competing with knownwell for the same patient demographic.
• Hims & Hers Health: Hims & Hers offers a weight loss program built around telehealth consultations and compounded GLP-1 medications, serving a similar mass-market patient profile to knownwell. With a publicly listed balance sheet and significant marketing spend, it competes on brand recognition and direct acquisition.
• Form Health: Form Health is a physician-led obesity medicine telehealth company providing FDA-approved medications (including GLP-1s) and lifestyle counseling. Like knownwell, it emphasizes physician-led, evidence-based care rather than compounded drugs or supplements, making it a close clinical peer.
• Sequence (now part of WW/WeightWatchers): Sequence, acquired by WeightWatchers, was a telehealth obesity clinic prescribing GLP-1s alongside behavior change programming. WW's national consumer brand combined with Sequence's clinical model makes it a direct competitor combining weight-management heritage with virtual prescribing.
• Mochi Health: Mochi Health is a virtual obesity medicine practice connecting patients with physicians for GLP-1 prescriptions and weight management care. Its telehealth-first, physician-led model and patient demographic overlap with knownwell's core offering.
• Calibrate: Calibrate is a clinician-supervised weight loss program combining telemedicine with coaching and accountability, and offers GLP-1 medications where appropriate. It targets a similar patient profile through a hybrid metabolic-care framing comparable to knownwell's positioning.
• Noom Health: Noom combines behavior-change coaching with a weight-loss program that increasingly incorporates clinician access and GLP-1 options via Noom Med. Its mass-market consumer base and digital-first delivery compete with knownwell's virtual channel for the same patients.

Broad incumbents

• Omada Health: Omada Health is an established virtual chronic disease management platform serving employer and payer populations with diabetes prevention, hypertension, and behavioral health programs. While not focused solely on obesity medicine, it competes for the same employer/payer contracts and risk-bearing opportunities knownwell is targeting.
• WW International (WeightWatchers): WW (WeightWatchers) is the legacy incumbent in consumer weight management, now repositioning around GLP-1-era care via the Sequence acquisition. It brings a large established subscriber base and consumer brand, competing with knownwell for the same patient population but with a much broader portfolio.

Others

• Eli Lilly (LillyDirect): LillyDirect is Eli Lilly's direct-to-patient digital healthcare platform that distributes knownwell's services. While a partner rather than a direct competitor, LillyDirect could at any time expand into providing its own end-to-end obesity care, shifting knownwell from partner to channel risk.
