BoobyBiome Raises £2.5M to Bring Oxygen-Excluding Breast Milk Storage to Market

Seed backing led by Empirical Ventures positions the UCL spin-out to advance a live microbiome supplement.

Overview

  • The seed round totals £2.5 million (€2.8 million) led by Empirical Ventures, with participation from The Helm, XFactor Ventures, Lavender Ventures, Kayan Ventures, Evenlode Investment, and angels including Dominic Hollamby and Lord Ara Darzi.
  • BoobyBiome’s patented device removes oxygen from bottles and storage containers to preserve live beneficial bacteria in expressed milk and extend freshness.
  • Company research cited in the coverage reports that many beneficial milk microbes begin to perish within about 20 minutes of oxygen exposure after expression.
  • Launch timelines reported by outlets differ, with The Times citing sales within six months while Tech Funding News reports a UK consumer launch in 2026.
  • A live microbiome drop derived from breast milk bacteria remains in development with clinical trials and planned peer‑reviewed publications, and the company emphasizes its products support families who cannot breastfeed.
