About Us

We are on a mission to redefine infant gut health through cutting-edge biotech innovation. Our brand is dedicated to solving one of the most critical global health challenges: the absence of essential Bifidobacteria in infants and toddlers. 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.

  • Assist in developing video scripts, interview questions, and storytelling formats for video content.
  • Work cross-functionally to ensure all content is scientifically accurate, engaging, and digestible for parents.

Content Performance & Optimization

  • Track key content performance metrics (engagement, conversion rates, SEO rankings).
  • Conduct A/B testing on headlines, CTAs, and formats to optimize content effectiveness.
  • Continuously refine content strategy based on audience insights and industry trends.
  • Collect customer and testimonial feedback for product/brand insights to leverage within messaging strategy.

  • Familiarity with social media content formats and best practices.
  • Background in DTC, health & wellness, parenting, or biotech brands is a plus.
  • Ability to collaborate with multiple stakeholders, including HCPs and influencers.

Why Join Us

  • Be part of a fast-growing, mission-driven brand that is redefining infant gut health.
