About Us

We are on a mission to redefine infant gut health through cutting-edge biotech innovation.

By restoring the gut microbiome, we are laying the foundation for lifelong health and disease prevention.

Our success is driven by a social-first, community-powered approach—leveraging education, influencers, healthcare professionals (HCPs), and parent advocacy to create a movement around early microbiome health.
