What is your typical day, and how do you make it productive?
I start early, usually before sunrise. I reserve the first hour for reading — research papers, journals, or market updates — before any emails or meetings. Mornings are for deep work: strategy, reviewing investments, or calls with founders. Afternoons tend to be more operational or philanthropic work. I guard my mornings from meetings, and I block time for uninterrupted thinking. Ending the day with a workout or walk clears my head.
How do you bring ideas to life?
I believe in surrounding ideas with smart people who challenge assumptions. I test ideas quickly — through pilots, founder discussions, or partnerships. The focus is always on execution, not perfection. A strong idea lives or dies by its ability to evolve with feedback.
What’s one trend that excites you?
The convergence of biotechnology and AI. We’re at the edge of unlocking human longevity and curing diseases that were once considered inevitable — and AI is compressing that timeline dramatically.
What is one habit that helps you be productive?
Time-blocking. Every Sunday, I pre-assign focus blocks for reading, work, and family. If it’s not on the calendar, it doesn’t happen.
What advice would you give your younger self?
Patience compounds. Focus on building things that will outlast you, and don’t measure progress too soon. Stay curious longer.
Tell us something you believe almost nobody agrees with you on?
That venture investing can be both mission-driven and generate outsized returns. Too often, people believe you have to sacrifice impact for profit, but I’ve found the two can reinforce each other when you’re disciplined.
What is the one thing you repeatedly do and recommend everyone else do?
Regularly unplug. Some of my best decisions came after intentional periods of detachment from constant information.
When you feel overwhelmed or unfocused, what do you do?
I step back and re-ground myself in my purpose — why I do the work I do. Often, that means a walk by the ocean or spending time with my kids, which recenters everything.
What is one strategy that has helped you grow your business or advance in your career?
Prioritizing relationships over transactions. Whether investing or philanthropy, long-term partnerships based on trust create compound returns — personal, professional, and financial.
What is one failure in your career, how did you overcome it, and what lessons did you take away from it?
Early in my career, I underestimated the importance of governance structures in venture-backed companies. I learned the hard way that great ideas without strong governance can unravel. Since then, I’ve made governance and founder support core parts of how I invest and build companies.
What is one business idea you’re willing to give away to our readers?
A longevity-focused concierge service — integrating genetic testing, personalized nutrition, and access to clinical trials for those serious about extending healthspan.
What is one piece of software that helps you be productive? How do you use it?
Notion. It’s my command center — I use it for tracking investment theses, organizing research, and structuring project pipelines. Its flexibility helps me connect ideas across domains.
Do you have a favorite book or podcast you’ve gotten a ton of value from and why?
Book: “The Price of Time” by Edward Chancellor. It’s a reminder of how interest rates shape economies, businesses, and lives — a valuable long-term lens for investing and building.
What’s a movie or series you recently enjoyed and why?
“Limitless with Chris Hemsworth” — it dives into cutting-edge science around human performance and longevity in an accessible but rigorous way. It parallels a lot of what I focus on in my work and philanthropy.
