Rythm Health

What Rythm Health does

Rythm Health, Inc. is a San Francisco-based, privately held consumer health company that operates a monthly at-home blood testing subscription. The core product is a painless, self-administered capillary dried-blood-spot device (requiring roughly 1 ml of blood, versus ~10 ml for venipuncture) shipped to subscribers every 30 days, with samples processed in Rythm's own in-house CLIA-certified, CAP-accredited, FDA-cleared laboratory. A single panel covers 50+ biomarkers spanning hormones, heart health, metabolic efficiency, thyroid, liver/kidney, and longevity, with results delivered in under 72 hours through a web and mobile dashboard that also surfaces a proprietary Rythm Score, Biological Age, Personalized Baselines, and AI-generated insights and coaching.

The company sells exclusively direct-to-consumer at $79 per month (first month discounted to $63.20), with HSA/FSA eligibility, a skip-up-to-90-days/cancel-anytime policy, and a 30-day money-back guarantee. The target customer is the health-conscious US adult across all 50 states, with use cases spanning athletic performance optimization, women's hormonal health, hormone therapy monitoring (TRT/HRT/GLP-1), preventative health tracking, and longevity. Customer acquisition runs through the company's DTC e-commerce storefront, iOS and Android apps, organic social media, a $20-per-referral program, a Dub.co creator partnerships program featuring celebrity and athlete endorsers (Odell Beckham Jr., Sara Blakely, Diplo, Daymond John, Cole Hocker, Jesse Itzler, Dr. Vonda Wright), earned media (Sports Illustrated, NYT, Rolling Stone, The Verge, New York Post), and experiential events such as Runningman 2025. A Trustpilot rating of 4.8/5 ("Excellent") across thousands of reviews and claimed "millions of results delivered" suggest established consumer traction.

Rythm reached a $100M valuation through a Series A round (Courtside Ventures participating, mid-2025) led by an eight-person founding team combining clinical laboratory leadership (Ph.D./MBA/NRCC Lab Director Dr. Zhiyi Qiang), medical direction (MD/MS/DABOM Medical Director Dr. Shawn Cole), and AI/data science (Ph.D./FACMG CSO Dr. Melissa Keinath; Ph.D. Data Science Director Dr. Bing Wang). The company is vertically integrated from device and lab through to dashboard, with regulatory credentials (CLIA, CAP, FDA Cleared, HIPAA Aligned, CLEP NY Approved) forming the structural barrier around its single integrated product surface.

Core offering

Rythm Health operates a monthly subscription at-home blood testing service. Subscribers receive a painless, self-administered dried blood spot collection kit every 30 days that captures ~1 ml of blood (vs. ~10 ml for a traditional venipuncture). Samples are processed in Rythm's own CLIA-certified, CAP-accredited, FDA-cleared US laboratory, with results delivered in under 72 hours through an AI-powered dashboard covering 50+ biomarkers across hormones, heart, metabolic, thyroid, liver/kidney, and longevity panels.

Product overview

Rythm Health operates a single integrated product platform centered on its monthly Rythm At-Home Blood Test subscription. The core offering is the painless self-collected capillary blood test kit, which feeds an AI-Powered Health Dashboard where members view their 50+ biomarkers, trend charts, and composite longevity metrics (Rythm Score, Biological Age, Personalized Baselines). Layered on top of the dashboard are subscription-included AI Coaching capabilities — natural-language chat and personalized insight/recommendation generation — that turn monthly results into tailored supplement, training, and lifestyle guidance. All samples are processed in Rythm's own in-house clinical laboratory (Rythm Lab), which is CLIA-certified, CAP-accredited, and FDA-cleared, providing clinical-grade accuracy without third-party lab involvement. The Rythm Mobile App extends the dashboard to iOS and Android. Together, the at-home test kit, the dashboard, the AI coaching layer, and the in-house lab form one vertically integrated diagnostic-as-a-service product rather than a platform with separately priced modules.

Direct peers

• Function Health: Function Health is a DTC subscription blood-testing service that screens 100+ biomarkers annually with physician review, directly competing with Rythm's monthly subscription model, biomarker panel breadth, AI dashboard, and longevity positioning. Like Rythm, it sells directly to health-conscious U.S. consumers without insurance billing.
• InsideTracker: InsideTracker offers DTC biomarker testing with personalized nutrition and longevity recommendations built on longitudinal data, overlapping Rythm's recurring testing, AI insights, and healthspan use cases. Both serve performance- and longevity-focused consumers willing to pay cash.
• Marek Health: Marek Health provides at-home blood testing with a strong focus on hormone optimization (TRT/HRT monitoring), overlapping Rythm's Hormone Optimization and Men's Health segments. Both combine at-home dried-blood-spot collection with clinician-facing results.

Broad incumbents

• Everlywell: Everlywell is a broad DTC home-testing platform offering dozens of tests (hormones, metabolic, sexual health, etc.) with a similar at-home collection kit and online results format. It is a larger, more established incumbent across many categories beyond Rythm's blood-only focus.
• Thorne HealthTech: Thorne combines at-home biomarker testing with a leading premium supplement line, offering OneGeno, Healthspan, and related panels. It overlaps Rythm in the longevity/biohacking consumer and bundles testing with supplement recommendations.
• Quest Diagnostics: Quest Diagnostics is the largest U.S. clinical lab network, providing the venipuncture-based blood testing Rythm explicitly positions against on price, convenience, and turnaround. Quest's consumer-direct offerings (e.g., QuestDirect) compete in the same DTC blood-test category.
• Labcorp: Labcorp is one of the two largest U.S. clinical labs and competes with Rythm both through physician-ordered blood work and through its own consumer-direct testing services. It represents the traditional incumbent model Rythm seeks to displace with at-home self-collection.

Emerging players

• Levels Health: Levels Health sells a continuous glucose monitor subscription paired with an AI-driven metabolic insights dashboard. It is adjacent to Rythm's metabolic biomarker offering and competes for the same biohacking/longevity consumer wallet, but with CGM hardware rather than at-home blood testing.
• Viome: Viome offers at-home microbiome and cellular health testing with AI-driven nutrition recommendations, overlapping Rythm's recurring testing, AI dashboard, and longevity positioning. It competes for the same proactive-health consumer, with a different sample type.

Others

• Cleveland HeartLab (Quest) / Cleveland Clinic lab services: Cleveland HeartLab and Cleveland Clinic Diagnostics represent the traditional hospital-affiliated specialty lab ecosystem that physicians use for advanced cardiovascular and metabolic biomarker panels. They serve as the clinical-grade benchmark Rythm positions against on accuracy and breadth.
