Today, I’m joined by Clara Sieg, co-founder & CEO of Loonen.

Born from Clara’s personal mission to avoid toxins in drinking water, Loonen’s ultra-filtered glass-bottled spring water emphasizes purity and transparency, rigorously tested for microplastics and PFAs.

In this episode, we discuss how water quality can influence health outcomes.

We also cover:

  • The aging US water infrastructure
  • National distribution and single-serve launch
  • Building a heritage American beverage brand
