Loonen offers still and sparkling water sourced from protected mountain springs in California, transported in stainless steel, purified through chemical-free membrane filtration, and then precisely remineralized with elements such as trace magnesium and Celtic sea salt. Every batch is verified by accredited third-party labs, with full contaminant reports accessible via QR codes on each bottle and box. Founded by venture investor Clara Sieg and beverage operator David Kimmell, the company positions itself as a transparent alternative to both municipal-source purified waters and minimally treated natural spring products that may carry contaminants. Loonen launched in December 2025 across Amazon and select California retailers, with broader national distribution planned for 2026. The company bottles exclusively in glass to avoid plastic leaching and backs its health claims with an advisory board of physicians and nutrition experts. To date, Loonen has secured $6 million in capital to fund operations and expansion. No revenue or user figures have been disclosed.
