Tiny Health Raises $33M To Explore What Gut Data Can Reveal About Future Health

What happened

Austin-based Tiny Health has raised $33 million in a Series B (an early stage of company funding) funding round led by B Capital to help it meet growing demand for its at-home microbiome tests. When Cheryl Sew Hoy ’s daughter developed eczema, allergies and food sensitivities, she began reading research on the infant gut microbiome.

Her daughter had been born by C-section, while her younger son, born vaginally, had no similar conditions. The contrast made her wonder whether differences in their early microbial exposure played a role.

While it did not give her a diagnosis for her daughter, it gave her an idea for a company. (Courtesy photo) A week after her son’s birth in 2020, she incorporated Austin-based Tiny Health .
