Episode Synopsis

200 VCs wanted to get into Lumen Orbit (YC S24)'s seed round!

Over the holidays, James Moffat and I had the pleasure of sitting down with Lumen's Co-Founder and CEO, Philip Johnston.

Drawing on his experience as a former Harvard University class president, McKinsey & Company consultant, and entrepreneur with a successful exit, Philip is now turning his focus to the stars. His mission? To revolutionize computing with solar-powered, orbit-based data centers that could redefine energy efficiency and scalability for AI.

Key Takeaways:

1. Be bold:
The biggest opportunities often lie in “zero-billion dollar markets”—industries that barely exist today but have massive potential, like computing in space. These untapped frontiers, often adjacent to big markets, are where transformative breakthroughs and category-defining companies are born.

2. Falling Launch Costs Are a Game-Changer:
Rockets like Starship will make getting mass into orbit 100x cheaper, unlocking opportunities like space-based data centers and other frontier innovations.

3. First-Principles Thinking Wins:
LumenOrbit tackles challenges by reducing them to their core engineering problems—like designing lightweight, cost-effective radiators capable of dissipating heat in the vacuum of space, a fundamental hurdle for high-energy applications.

4. New Industries Offer Rapid Expertise:
In emerging fields like AI and space tech, focused effort can make you an expert in months. Aspiring entrepreneurs and new grads should target fast-growing industries with room for newcomers.
