San Francisco longevity start-up raises $27 million in Series A funding in a round led by Khosla Ventures.

Celine Halioua, the Founder and CEO of Loyal, a company that works collaboratively with dog owners and the world’s leading aging scientists to develop the first FDA-approved therapies to enhance dogs’ wellbeing and lead to better, longer lives, has announced her company has raised $27 million in its Series A round.

Led by Khosla Ventures, investors included First Round Capital, Box Group, Collaborative Fund, The Longevity Fund and Lachy Groom; these are companies that played a part in Loyal’s 2020 $11 million seed round. Since its foundation in 2019, Loyal has raised a total of $38 million and shows no signs of stopping.

Longevity.Technology: It’s a dog’s life, but perhaps soon it will be a long dog’s life! Halioua is dedicated to developing medicines for for aging and the diseases of aging and Loyal works collaboratively with dog owners and the world’s leading aging scientists to develop the first FDA-approved therapies to enhance dogs’ wellbeing and lead to better, longer lives. With two drug candidates poised to enter clinical trials, and an ongoing observational study designed to track specific biomarkers in dogs of different breeds, ages and sizes to better understand why small breed dogs live longer, it’s no wonder investors find Loyal’s prospects intriguing.

As well as Tweeting about the raise, founder and CEO Halioua also took to Twitter to make the point that Loyal “got 50/50 gender parity in the Series A!”

“I challenge all founders to hit at least 25/75 in your next round, and VCs to encourage and support their founders to put in the time to ensure the SV flywheel supports more women,” she added [1].

Halioua is committed to moving the aging field forward. The idea behind Loyal was sparked when she realised she was seeing company after company pitch a fund for age-related interventions that were focused on indications that often seemed far-removed from aging.“At that point, nobody was developing a drug explicitly for aging,” she told Longevity.Technology. “ I spent a year trying to figure out how do it in humans and came to the conclusion that it couldn’t be done without a billion dollars, which I didn’t have.

But dogs seemed to present a perfect intersection of my skill set – market need, biological low-hanging fruit, and also the ability to actually test a drug for aging – healthspan and lifespan. All within a timeline that makes sense from a commercial and venture scale point of view.”

Loyal works on the understanding that by researching how to improve healthspan and extend lifespan in our canine companions, light will be shed on human aging pathways. Add in that epigenetic factors affected by environment are the same for both dogs and humans – good diet vs bad diet, exercise vs lack of, pollution, &c – and also that both species can develop similar diseases of aging, such as cancer, arthritis or cardiac problems, and suddenly the model seems incredibly apt.

As well as developing an animal pharmaceutical company working on therapies for dog longevity and wellness, Loyal is using companion dog citizen science studies of over 500 dogs to better understand dog aging with a long-term aim of leveraging the R&D for human therapies.

We recently spoke to Celine Halioua about her work in the dog longevity field and also interviewed Matt Kaeberlein about why studying man’s best friend makes good longevity sense.

Loyal

Longevity level(s):

  • Level 6: Aging disease prevention therapeutics
    Therapeutic interventions that control aging drivers to prevent aging diseases from occurring, like the current wave of GLP-1 agonists that prevent type 2 diabetes through metabolic interventions that also are proving effective in mitigating cardiovascular and neurological diseases.
  • Level 7: Targeted aging disease reversal
    Therapeutic interventions that stop or reverse age-related damage in specific organs (organ specific / tissue specific / localized reversal) or for age-related diseases including technologies like partial cellular reprogramming.

Overview

Loyal is a clinical-stage veterinary medicine company focused on developing pharmaceutical interventions to extend both the lifespan and healthspan of dogs through targeted modulation of aging pathways. The company's lead therapeutic candidate, LOY-002, is a once-daily oral formulation designed to improve metabolic health and insulin sensitivity in senior dogs aged 10 years and older. By leveraging canine models to understand fundamental aging mechanisms conserved across mammalian species, Loyal aims to establish proof-of-concept for longevity therapeutics that may eventually inform human aging interventions. The company's mission centers on translating geroscience discoveries into practical treatments that enhance quality of life in aging animals while advancing the broader field of longevity medicine.

Now a science and medicine journalist, Eleanor worked as a consultant for university spin-out companies and provided research support at Imperial College London and various London hospitals in a former life.

With a keen interest in all things geroscience, Eleanor covers the biological mechanisms of aging, highlighting how interventions – from nutritional strategies to advanced therapeutics – can influence the aging process at a cellular level. She also investigates the broader implications of aging research, including the integration of longevity science into healthcare strategy and the expanding wellness economy. Her work (hopefully) provides insights into how these developments are shaping the emerging landscape of healthspan optimization and age-related innovation.
