Tiny Health Raises $33 Million for Gut Data Health Insights

Tiny Health, a health technology company, has announced the closing of a $33 million Series B funding round. The round was led by B Capital, with participation from existing investors including Spero Ventures, The Venture City, and Overwater Ventures, as well as new investors.

The company focuses on leveraging gut microbiome data to predict future health outcomes. Tiny Health develops and offers at-home tests that analyze an individual's gut microbes. The company has experienced substantial revenue growth, with its B2B division, 'Powered by Tiny,' which supplies tests to healthcare providers and other companies, quadrupling in revenue last year.

Founded by Cheryl Sew Hoy, the company was inspired by her daughter's health issues, leading to research on the importance of the infant gut microbiome. Tiny Health's technology utilizes shotgun metagenomic sequencing for a comprehensive analysis of the microbiome. They offer tests for infants, pregnant individuals, and adults.

With the new funding, Tiny Health plans to expand its operations, further develop its platform, and enhance its offerings for healthcare professionals. The goal is to make microbiome research more accessible and understandable to both consumers and clinicians, aligning with the growing trend in preventive healthcare.

Tiny Health's tests are not diagnostic; they provide insights into the microbiome and suggest potential next steps, such as dietary changes. The company operates in a sector with other players like Throne Science, which is developing different health technology solutions.
