Nearly three decades.
Five companies.
One mission — fulfilled.

What began in a small Welsh laboratory became a platform that turned breakthrough science into companies built to change lives. Every programme that started at Neem has found its home. The mission is complete.

The Neem Story

In 1998, Neem Biotech started with a conviction: that nature, properly understood, held answers to some of the hardest problems in human and planetary health. From a niche contract research business exploring the medicinal properties of the neem tree, it grew into something far more ambitious — a drug-discovery and venture-building platform tackling antimicrobial resistance, biofilm disruption, rare disease, and the environmental footprint of agriculture.

Over nearly three decades, Neem became a place where scientists, entrepreneurs and operators turned ideas into de-risked, spinout-ready companies. It took programmes from first principles through to pre-clinical development, then gave each one the independence and focus it deserved.

From wound healing to rare genetic disease. From chronic infection to the methane emissions of livestock. Each challenge found its team, its funding, and its path forward — born inside Neem, built to stand on its own.

By 2026, every programme has graduated. The incubator has done its work. And the science Neem nurtured now lives on under five different names, in the hands of the companies built to carry it to patients, farmers, and communities around the world.

The work lives on

Five companies. Five missions. One inheritance.

The technologies, programmes and ambitions that took shape inside Neem now sit with the teams best placed to carry them through — to patients, farmers, consumers and the communities they serve.

Onya TherapeuticsWound Care · UK

Pharmaceutical treatments for chronic and acute wounds. Active Exudate Therapy delivered through a patented silicone-matrix patch. From care to cure.

Mariposa TherapeuticsRare Disease · UK

A novel topical therapy for patients with Epidermolysis Bullosa — addressing both blister formation and infection where no curative treatment exists today.

MootralClimate & Agriculture · UK / Switzerland

A true pioneer in enteric methane reduction. Using Neem’s garlic and citrus bioactives, Mootral proved that a natural feed supplement could measurably cut greenhouse gas emissions from cattle — and then invented CowCredits, a Verra-certified carbon credit mechanism that drove climate finance directly back to farmers. Brave, early, and ahead of a market that has yet to arrive.

AvanterraRestorative Agriculture · In formation

Mootral’s natural successor. When the market is ready, Avanterra will carry forward the pioneering work in enteric methane reduction, antimicrobial resistance in livestock, and the virtuous cycles of restorative animal agriculture.

Coming soon

InQpharmConsumer Health · Global

A two-decade incubator of self-care technologies, partnering with the world's leading consumer health companies to bring root-cause solutions to market.

Thank you

Building Neem was never a solo endeavour. It took extraordinary people — scientists, operators, partners and friends — who believed that nature-derived science could solve problems the world had given up on. We owe each of them more than a single page can say.

To the people who shaped this journey, some of whom were part of Neem from its very inception: Rob Saunders, Gareth Evans, Dan Blandford, Michael Graz, Stacey Holborn, Graham Dixon, Phil Dudfield, Stuart Clark, Tracy Nevitt, Dan Neef, Lucy Sykes — and so many more who gave their talent, conviction and years to this mission. You were instrumental in making Neem what it became. The companies that carry this work forward exist because of what you built.

To every collaborator, customer, business partner and friend who walked some part of this road with us — thank you. The science you helped build is now in good hands. And the work, as it always was, continues.
