Tiny Health raises $33 million to advance infant gut microbiome tests

Tiny Health, an Austin-based startup focused on infant gut microbiome testing, raised $33 million in a Series B funding round led by B Capital, the company announced.

Tiny Health, an Austin-based startup focused on infant gut microbiome testing, raised $33 million in a Series B funding round led by B Capital, the company announced. This latest round brings the total funding raised by Tiny Health to $46 million since its founding in 2020. The company offers at-home microbiome tests aimed at understanding early-life gut health and its impact on future conditions such as eczema and allergies, according to news.crunchbase.com.

The company was founded by Cheryl Sew Hoy after observing differences in health outcomes between her two children, one born via C-section and the other vaginally. Sew Hoy incorporated Tiny Health a week after her son's birth in 2020. The Series B round included participation from existing investors Spero Ventures, The Venture City, and Overwater Ventures, alongside new investors Black Opal Ventures and Alumni Ventures. Nick Whitehead from B Capital will join Tiny Health’s board, the report said.

Tiny Health’s approach addresses growing interest in the microbiome’s role in early childhood health. The company’s at-home tests aim to detect beneficial bacteria deficiencies that may contribute to infant health issues. The $33 million Series B round follows a $4.5 million seed round in 2021 and an $8.5 million Series A in late 2023, reflecting increasing investor confidence in microbiome-based diagnostics and personalized health interventions.

Tiny Health plans to use the new funding to expand its product offerings and scale operations. The company’s total funding now stands at $46 million, positioning it to further explore how gut data can reveal insights into future health outcomes for infants, according to news.crunchbase.com.
