The Postbiotic Company secures pre-seed investment to pioneer the next generation of gut health

The Postbiotic Company is pioneering the next generation of gut health with its flagship product: fermented Bhutan turmeric postbiotics.

Unlike standard turmeric supplements, the company’s proprietary fermentation process transforms wild-harvested Bhutan turmeric into powerful postbiotics — beneficial compounds that support the gut microbiome and overall wellness. Clinical trials demonstrate a 22% reduction in inflammation markers, backed by rigorous scientific validation. Sourced from the pristine Himalayan kingdom of Bhutan and fermented in Japan using traditional methods combined with modern science, the company delivers authenticity and efficacy in every tablet.

Alongside product development, founder Alastair Jessel is actively educating consumers on the science of postbiotics through his Substack, “A Man of Kent”, where he shares in-depth articles exploring gut health, inflammation, and microbiome innovation. You can read the substsack article here.

The round was completed through the FounderCatalyst platform, a cost-effective and rapid fundraising solution designed for early-stage startups.

“The Postbiotic Company completed their funding round using the FounderCatalyst platform, all for a fixed fee of £1,495. A very exciting phase of growth lies ahead.”
Max Heal, CEO at FounderCatalyst

Founded by Alastair Jessel, The Postbiotic Company will use the investment to accelerate UK market entry and expand into Germany, the Middle East, and the USA, building on its world-exclusive rights to this clinically validated product.
