Tiny Health raises $33M for microbiome AI

Tiny Health raised an oversubscribed $33 million Series B, bringing total funding to $46 million, and committed $5 million to a microbiome research program. The company’s announcement says TinyAI is trained on nearly 200,000 microbiome profiles and that the platform serves nearly 200,000 customers plus more than 6,000 healthcare practitioners; capital will expand clinical studies and its B2B platform. For builders, the archive’s clinical-AI evidence check is the useful comparison: dataset scale can fund personalization, but it does not substitute for prospective validation.
