AI-Generated Summary
Key Takeaways
- ✓Milestone-Based Biotech Fundraising: Deep tech companies raise capital differently than software startups. Instead of revenue metrics, biotech valuations increase as a fraction of future market value with each milestone that raises probability of FDA approval. Loyal mapped regulatory milestones (efficacy, safety, manufacturing) years in advance, understanding that investors underwrite specific FDA approvals, not just promising data.
- ✓Conditional Approval Pathway: Loyal secured FDA efficacy and safety approval for their first drug before full market launch, eliminating the primary biological risks that cause most drugs to fail. With manufacturing as the remaining hurdle, the company shifted from existential risk to execution risk. This transformed investor conversations from whether the drug works to when it launches, fundamentally changing valuation dynamics.
- ✓Dogs as Human Drug Accelerators: Developing longevity drugs in dogs first solves the human drug development paradox. Dogs age naturally with diseases like dementia and cancer, providing better translational biology than mice (9% human drug success rate). A dog lifespan study costs approximately $50 million versus billions for humans, with results in years not decades, creating viable economics for private funding.
- ✓Clinical Trial Scale and Design: Loyal runs the largest animal health clinical trial in history with 1,300 pet dogs across 70+ veterinary sites. The double-blind study tracks quality of life, disease development, and lifespan until death. This consumer-driven pharmaceutical model mirrors GLP-1 weight loss drugs, where pet owners request the treatment from veterinarians rather than traditional pharma marketing approaches.
- ✓Revenue-Funded Moonshots Strategy: Unlike most biotech companies that exit to pharma before commercialization, Loyal plans direct-to-consumer sales through veterinarians in a cash-pay system. This revenue engine (targeting five dog drug approvals by 2030) will fund expensive human longevity trials without relying on pharma acquisition, following the Tesla model of using current product revenue to fund increasingly ambitious next-generation development.
What It Covers
Celine Halioua, founder of Loyal, explains her strategy to develop FDA-approved longevity drugs for dogs first, having raised over $250 million. She details milestone-based fundraising for biotech, regulatory pathways, clinical trials with 1,300 dogs, and plans to translate findings into human longevity treatments.

Notable Moment
Halioua reveals her early fundraising mistake: celebrating internal efficacy data a year before FDA approval, expecting investors to value it immediately. She learned investors cannot underwrite raw data without regulatory expertise, but can easily diligence a two-page FDA approval letter, teaching her to map milestones from the investor perspective, not the scientist perspective.
Episode Transcript
Hey, everybody. This is Ben Kesnoka, cofounder and partner at Village Global, a network driven venture firm. And this is our podcast where we go deep on all things business and technology with world leading experts. Thanks so much for joining us today, Celine. Great to have you on. Excited to be here. So to start, I'd love to just hear a little bit about this founding of the company. Can you tell me a little bit about your own history kind of up to the point where the company began? Oh my god. I mean, how long do we have? Do you want, like, the TLDR? Do we want the TLDR? The TLDR? Okay. I got into college for art school. Summer before I started, had a total, like, existential crisis, realized that, you know, biology in our bodies and health is actually the determinant of our free will and switched to neuroscience, got really interested in the biology of aging, worked on the biology of aging for a while, became obsessed with how could we get the first drug approved that's not just targeting end stage disease, but instead the processes by which we break down and age over time. Initially, I was doing that in humans, worked on human biology and venture and otherwise for a while, and then realized, actually, I think the best way to get a longevity drug through to market and to the consciousness writ large was to go dogs first. And I guess, like, while all of this is happening, there's, like, a parallel path of, like, I'm a crazy animal person. So it all kinda worked out really well. Dogs, cats, horses. All of the above. Squirrels, turtles, catchers. My dog does not like squirrels. Squirrels and dogs is a dangerous mix. It is a dangerous mix. Thankfully, there are no squirrels today, but I may or may not have had, we used to rescue a lot of, like, wild animals when I grew up in Texas. And so we definitely had baby squirrels. There was one living in my aunt's house. It was it was a thing. That's very Texas. Yes. It truly, truly very Texas. That's amazing. And can you tell me a little bit about the state of Loyal today? Like, how many people is it? What are the products that you have? Like, just what does the business look like? So I'd say we're, like, a mid stage consumer biotech company working on developing the first FDA approved drugs for lifespan extension, going dogs first. We have raised now over a quarter of $1,000,000,000, which is honestly, like, a combination of interesting, exciting, and terrifying to say out loud. Unpack that. Well, it's like, okay. It's like, holy shit. Like, if you had told me, you know, five or six years ago and I started loyal, and I was like, oh my god. I raised $5,000,000 seed. Wow. Like, that's crazy. If you had told me that …
