What Protocol does
Protocol is a private longevity medicine practice operating under Healthspan Group LLC, headquartered in Boston, MA with services also delivered in New York City. The company provides a membership-based health optimization service built around nine evidence-based clinical protocols, each targeting specific biomarkers and measurable outcomes: cardiovascular risk (ApoB), muscle and body composition (DEXA/ALMI), metabolic health (HOMA-IR with CGM), physical capacity (VO2 max), sleep (ISI), nutrient optimization (7 biomarkers), hormonal health (12 markers), with two forthcoming protocols for cancer prevention and emotional resilience. The technology foundation integrates wearable data, continuous glucose monitoring, and a longitudinal tracking dashboard that connects biomarker trends across domains. The practice deliberately caps physician panels at 50 patients (versus approximately 2,500 for typical primary care), positioning the model as a high-touch alternative to both standard annual physicals and higher-priced concierge offerings.
The business model is a recurring subscription at $695 per month with a 12-month commitment, or $7,500 prepaid annually, gated by a one-time $1,500 Foundation Assessment that establishes baseline biomarker measurements, body composition via DEXA, mobility testing, and a personalized Longevity Plan. Optional advanced screening (Galleri liquid biopsy, whole-body MRI) is offered as add-ons, with many services potentially HSA/FSA reimbursable. The 30-day satisfaction guarantee and 12-month commitment create predictable cash flow per member. Go-to-market is sales-led: content marketing (a 40+-article blog), SEO, paid search (Google Ads, Meta), a twice-monthly email newsletter, a free 60-second plan builder, and a partner program for referring physicians and practitioners. The team is led by CEO Matt Brockman and Chief Scientific Officer Dr. Gil Blander, PhD (founder of InsideTracker), with 14 total employees plus clinical advisors. The company is privately held with no disclosed venture funding, operates domestically in the U.S. Northeast, and is HIPAA-compliant as a Business Associate alongside partner practices.
Customer outcomes reported in a 214-member cohort include ApoB optimal attainment rising from 27% at intake to 69% during membership, a median ApoB of 79 mg/dL (versus a U.S. population mean of approximately 95 mg/dL), 88% of members with ApoB below 100 mg/dL, a 95% rate of cardiovascular risk stabilization or improvement on AHA PREVENT equations, and an average biological age 3.8 years younger than chronological age across 68 members using the Levine PhenoAge algorithm.

Protocol product offering
Product offeringCore offering
Protocol is a longevity medicine practice that delivers proactive health optimization through a one-time Foundation Assessment (expansive bloodwork, DEXA body composition scan, mobility testing, and a personalized Longevity Plan) and an ongoing Membership ($695/month or $7,500/year) that grants access to nine evidence-based protocols targeting cardiovascular risk, muscle and body composition, metabolic health, physical capacity, sleep, nutrients, hormones, emotional resilience, and cancer prevention. Members are supported by a deliberately small clinical team (physicians, healthspan directors, health coaches, registered dietitians, nurse practitioners) that uses a longitudinal dashboard, 12-week retest cadence, and risk-tiered targets to drive measurable biomarker improvements.
Product overview
Protocol is a longevity medicine and health optimization practice offering a platform of 9 evidence-based health protocols, each targeting specific biomarkers and measurable outcomes. The core offering consists of a Foundation Assessment ($1,500 one-time or included with membership) that establishes baseline health metrics, and a monthly Membership ($695/mo) providing access to all protocols and a dedicated clinical team. The 9 protocols include: Cardiovascular Risk (ApoB), Muscle & Body Comp (ALMI/DEXA), Metabolic Health (HOMA-IR/CGM), Physical Capacity (VO2 max), Sleep Health (ISI), Nutrient Optimization (7 biomarkers), Hormonal Health (12 markers), plus two forthcoming protocols (Emotional Resilience/HRV and Cancer Prevention). Case studies demonstrate outcomes across body composition, cardiovascular risk, and biological age reduction.

Protocol competitors and assessment
Company assessmentBroad incumbents
- MDVIP: Largest concierge medicine network in the US with 1,000+ affiliated physicians offering smaller patient panels and 24/7 access. Competes for the same premium primary care segment with broader national geographic reach but reactive primary care playbook versus Protocol's structured, biomarker-led protocols.
Direct peers
- Fountain Life: Premium longevity medicine practice offering executive health assessments starting at $19,500+, with whole-body MRI and advanced diagnostics. Targets the same affluent, prevention-focused demographic as Protocol at a higher price point with a screening-heavy rather than protocol-coaching approach.
- Lifeforce: Longevity-focused membership practice combining at-home diagnostics, biomarker tracking, and clinician consultations on a monthly subscription. Directly comparable membership pricing structure and longevity/healthspan positioning aimed at the same 40-65+ affluent, proactive demographic.
- InsideTracker: Biomarker-based health optimization platform founded by Protocol's own CSO Dr. Gil Blander; now owned by LetsGetChecked. Closest direct competitor in scientific methodology, biomarker philosophy, and target demographic of health-conscious adults seeking optimization beyond standard labs.
- Function Health: Direct-to-consumer biomarker testing platform offering comprehensive panels and physician-reviewed results. Targets the same health-conscious, biomarker-curious consumer as Protocol but operates without an in-house clinical care team, positioning itself as the 'testing' alternative Protocol explicitly positions against.
- Parsley Health: Functional medicine membership practice offering root-cause primary care with health coaching and nutrition support on a subscription basis. Similar clinical team structure (MDs, NPs, health coaches) and recurring-revenue model targeting health-conscious consumers seeking alternatives to standard primary care.
Emerging players
- Everlywell: At-home health testing platform offering direct-to-consumer labwork across hormones, thyroid, food sensitivity, and other panels. Partial overlap in delivering biomarker data to consumers but lacks Protocol's longitudinal coaching, clinical team, and protocol-driven action layer.
- Forward Health: Tech-forward preventive primary care membership combining advanced screening, wearables, and AI-driven health insights with a consumer-brand experience. Targets a similar prevention-focused, design-conscious consumer but with proprietary tech infrastructure and a tech-startup GTM rather than a clinical-team-first model.
Others
- LetsGetChecked: At-home diagnostics platform that acquired InsideTracker in 2021, offering direct-to-consumer testing plus the InsideTracker biomarker optimization service. Comparable in the biomarker-driven consumer health space but at infrastructure scale, including lab ownership and B2B health plan distribution that Protocol lacks.
- Thorne: Supplement and at-home testing company offering direct-to-consumer labwork with health insights. Adjacent in the biomarker-aware consumer wellness space, with overlap on consumer education around nutrients and longevity, but primary business is supplements rather than clinical care delivery.
