Company Performance Metrics
Flore Inc. is a personalized probiotic and microbiome company that designs custom probiotic formulations based on individual gut microbiome sequencing. Headquartered in Joliet, Illinois, and founded in 2025 through the acquisition of Sun Genomics' assets, Flore combines whole-genome microbiome analysis with tailored probiotic manufacturing to
move beyond the one-size-fits-all supplement model. The company operates across three channels: a direct-to-consumer personalized probiotic platform (flore.com), a B2B clinical provider channel serving practitioners (Flore Clinical), and a premade consumer product line, Real Good Ones. This tiered architecture is unified by a shared microbiome data spine, allowing customers to move from off-the-shelf products into fully personalized, sequencing-driven formulations. Flore's approach is grounded in real-world evidence from a longitudinal dataset spanning tens of thousands of subjects, and the company is actively advancing clinical research, including a bacteriophage intervention study in autism spectrum disorder in collaboration with academic investigators. Flore is led by CEO and co-founder Craig Rouskey and COO and co-founder Megan Crocker.
