About Gamgee
Summary
Gamgee builds a personalized mRNA vaccine platform for dogs diagnosed with cancer. Starting from a dog's tumor biopsy, Gamgee sequences both cancerous and healthy DNA, pinpoints the mutations specific to that cancer, and manufactures a vaccine designed to direct the immune system against those targets. The platform handles each step from initial vet coordination and tissue collection through genomic analysis, vaccine production, administration by a veterinary oncologist, and response monitoring, replacing the ad hoc, trial-and-error approach that defines current veterinary oncology.
Go-to-market
Dog owners and veterinary oncologists are the entry points: owners register interest directly on the website, and Gamgee works with the dog's existing vet to coordinate sample collection and treatment delivery. Active clinical trials in Australia anchor the current case intake, with registrations accepted from owners worldwide.

Scalable Personalised Cancer Treatment
Gamgee began with Rosie, founder Paul Conyngham’s dog. After surgery, chemotherapy and immunotherapy failed, Rosie was given months to live. Paul used AI and genomic analysis to identify targets in her tumour, then worked with scientists at UNSW to produce what is believed to be the first fully computationally designed mRNA cancer vaccine delivered to a dog. Following treatment, several tumours shrank significantly and her quality of life improved Gamgee is building an end to end platform for personalised mRNA cancer vaccines for dogs. We sequence a dog’s tumour and healthy DNA, identify mutations unique to its cancer, and design a vaccine that teaches the immune system what to attack. We manage the entire process- from vet intake and tissue collection through genomic analysis, vaccine production, treatment and response monitoring We are now turning that one off effort into a repeatable clinical system. Gamgee is running clinical trials in Australia, working with vets, oncologists and specialised laboratories, and accepting cases globally. Our goal is to make personalised cancer treatment accessible to every dog that needs it- and use each case to improve the treatment for the next
