Tiny Health, based in Austin, has raised $33 million in Series B funding led by B Capital. The company offers at-home microbiome tests that let consumers analyze their gut bacteria and learn what that data might suggest about future health. It said the new capital will help it keep up with growing demand for the tests.

The round underscores continued investor interest in consumer-facing diagnostics. By bringing laboratory-grade analysis into the home, Tiny Health is competing in a category that promises more direct access to personal biological information.
