# Colin Topham – Cal.com booking page

> I'm Colin, the founder of AlchemyPet.

My soul dog Marley inspired the question at the heart of the company:

what if delivery matters more than dosage?


AlchemyPet is my answer. Swiss-engineered cold-process microencapsulation that protects delicate actives and delivers up to 7x greater bioavailability through targeted gut delivery. Clean label, absorption-first, built for dog owners who actually read labels.

Real science, real love.
