Uncover the future of aging with Loyal, the biotech company leading a quiet revolution. Led by founder Celine Halioua, Loyal is unravelling the fundamental mechanisms of pathological aging in our beloved companions.
Their mission? To extend the healthy lives of dogs and, in doing so, reveal unprecedented insights into human longevity.
Loyal joins the 2025 Forbes Next Billion-Dollar Startups list and involves the largest animal clinical trial ever conducted, enrolling 1,300 dogs across 70 veterinary clinics nationwide. The goal: to give dogs "one healthier year" and yield a "gold mine of data" that will fundamentally advance the understanding of aging in both canines and humans.
Could the secret to a longer, healthier human lifespan be found in the journey of our canine companions? Loyal's unofficial slogan hints at the profound answer: "save the dogs, save the world".
