In this episode of The Eric Ries Show, I'm joined by Celine Halioua, founder and CEO of Loyal, a groundbreaking biotech startup developing drugs to extend dogs' healthspan and lifespan. Celine's journey combines her passion for animals with a bold scientific mission that looks beyond pets to potentially transform human longevity as well.

Our conversation explores:

• Why ambitious, moonshot visions can paradoxically make fundraising and team-building easier

• The critical early pivot that positioned Loyal for its first drug approval

• The undervalued power of listening deeply and asking the right questions

• Loyal's philosophy of exceeding regulatory requirements to build trust and advance the field

• Balancing the startup need for speed with scientific rigor and safety

• How Celine's background led her to focus on the untapped potential of canine longevity

• The competitive advantage of pursuing novel ideas before they become industry trends

• Why founder conviction and scientific expertise were crucial to overcoming skepticism

• Celine's approach to governance and maintaining mission control for the long-term

• Navigating the challenges of Silicon Valley as a female founder in biotech

• The realistic timeline and milestones for Loyal's drug development and approvals

• Building for truly long-term impact beyond conventional startup timelines

• And much more!
