Consumer telehealth · At-home microbiome testing
Tiny Health
Tiny Health sells at-home gut and vaginal microbiome tests for babies, children, and adults, analyzed with shotgun metagenomic sequencing, with reports, coaching, and a version practitioners order for their patients.
Strong fit
- Parents who want to look into a baby's eczema or gut symptoms with their doctor
- Practitioners who want a microbiome test with reports they can use with patients
- Adults paying with HSA or FSA funds who want repeat gut testing
Weak fit
- Anyone who wants a diagnosis, which Tiny Health says its tests do not give
- Patients who want insurance to pay
- People who want answers from one test without changing diet or habits
Bottom line
Tiny Health is a wellness microbiome test, strongest for babies and young children, with reports that suggest diet and other changes and a practitioner channel that is its fastest-growing business. It suits parents and clinicians who want detailed gut data. It does not diagnose disease, and insurance does not cover it.

Tiny Health is used by parents, adults, and the practitioners who treat them. A customer swabs a small stool sample at home and mails it in, then gets a report on the microbes found, what they may be doing, and suggested next steps such as diet changes, with links to research, according to Crunchbase News. Tests use shotgun metagenomic sequencing, which reads microbial DNA across the whole sample.
The baby gut health test costs $249, according to Tiny Health's store, and Tiny+ memberships bundle two tests with a coaching session and add more kits at $169 each. Tests are HSA and FSA eligible. Insurance does not cover them, and founder Cheryl Sew Hoy told Crunchbase News: “We are a wellness test. We’re not a diagnostic.”
HIR has not reviewed another microbiome testing company. The closest consumer health companies on HIR are Allara Health, Sesame, Found, and Alloy, which sell cash-pay care direct to patients.
Cheryl Sew Hoy incorporated Tiny Health in Austin a week after her son was born in 2020 and launched the baby test in 2022. On September 29, 2026 the company announced a $33 million Series B led by B Capital, bringing total funding to $46 million. It says it has served nearly 200,000 customers and more than 6,000 practitioners, including Mayo Clinic's Executive Health and Longevity Clinic, Atria, Superpower, and Fullscript, and Sew Hoy said revenue has more than doubled each year.
Tiny Health has published four scientific papers, including one that found infants in its personalized program had 83% lower odds of developing eczema and allergic conditions, according to Sew Hoy's letter on the round. It is putting $5 million of the new money into a research program. A microbiome test can show which microbes are present, but it cannot show what caused a person's symptoms.
