What Tiny Health does

Tiny Health is a US-based precision microbiome wellness platform founded in 2020 by Cheryl Sew Hoy and commercially launched in 2022, headquartered in Austin with 11-50 employees. The company operates at-home gut and vaginal microbiome test kits processed through a CLIA-certified, CAP-accredited US laboratory partner using shotgun metagenomic sequencing, with HIPAA-compliant data handling and a proprietary strain-level database described as the largest repository of pregnancy-and-baby gut microbiome samples in the world.

The product surface is organized as a platform-plus-modules architecture: five life-stage core tests (Baby, Child, Adult, Pregnancy, Vaginal) priced at $249 each, upgradeable into Tiny+ annual memberships at $399/year that add repeat testing, functional-health coaching, and evolving personalized Action Plans; condition-specific Targeted Programs (C-section Gut Recovery, Eczema Gut Rebalance, Optimize, Chronic Conditions, Digestive Issues, Fertility/Pregnancy/Postpartum) layer further monetization. Proprietary AI/ML capabilities include the Gut Maturation Index (predicts a child's gut microbiome age with 1-2 month accuracy up to age three), Pathogen Strain Tracking, Bacterial Toxin Genes, and the newer Microbiome Age Research Edition extending microbiome-age scoring into the adult longevity category.

Revenue is generated through three motions: (1) direct-to-consumer e-commerce at tinyhealth.com and store.tinyhealth.com, with HSA/FSA support via TrueMed; (2) the Tiny+ subscription program, which converts one-time buyers into annual recurring revenue; and (3) the Powered by Tiny B2B platform, a white-label/API channel that embeds Tiny Health's sequencing, lab processing, and reporting infrastructure into health systems (Mayo Clinic Executive and Longevity Health Programs), longevity clinics (Pritikin), consumer health brands (Superpower, Mito Health, Tastermonial, ProteusDx, resbiotic, Bristle Health), and practitioner channels (Rupa Health, Evexia Diagnostics). By December 2025 the company reported 100,000+ tests processed, 3,000+ practitioners, and earned-media coverage in Washington Post, Fortune, WSJ, CNN, NBC, and Fox News, with a published RCT in Pediatric Allergy and Immunology showing 83% lower odds of eczema in C-section babies receiving its intervention.

Core offering

Tiny Health sells at-home shotgun metagenomic microbiome test kits for babies, children, adults, pregnant individuals, and vaginal health, processed at a US CLIA-certified, CAP-accredited lab and delivered as personalized Action Plans. The kits are sold either as one-time purchases ($249 each) or wrapped into annual Tiny+ subscription memberships ($339-$399/year) that bundle repeat testing with one-on-one functional health coaching. The same sequencing and analytics stack is also licensed via the Powered by Tiny B2B white-label platform to health systems, longevity clinics, and consumer wellness brands.

Product overview

Tiny Health operates a platform-plus-modules architecture for at-home microbiome testing. The core platform is a CLIA-certified, CAP-accredited, HIPAA-compliant shotgun metagenomics pipeline that powers a family of life-stage-specific core tests — Baby Gut Health Test, Child Gut Health Test, Adult Gut Health Test, Vaginal Health Test, and Pregnancy Gut Health Test — each of which can be upgraded into an annual Tiny+ subscription (Tiny+ Baby, Tiny+ Child, Tiny+ Adult, Tiny+ Vaginal, and Tiny+ Family Membership) that adds periodic re-testing and Functional Health Coaching. Wrapping these tests are targeted gut-health programs (C-section Gut Recovery, Eczema Gut Rebalance, Baby's Gut Conditions, Child's Gut Conditions, Optimize, Fertility/Pregnancy/Postpartum, Chronic Conditions, Digestive Issues, and a Vaginal Health program) that condition the personalized Action Plan on specific goals. Cross-cutting analytics modules — Gut Maturation Index (predicting a child's gut microbiome age), Pathogen Strain Tracking, Bacterial Toxin Genes, and the newer Microbiome Age Research Edition (extending microbiome-age scoring to longevity) — run on top of the same sequencing data, and the entire stack is also offered white-label to brand partners through the Powered by Tiny B2B platform (e.g., the resbiotic® Gut Health Test).
