Lessons from building Jebbit

How do you spot a frontier-tech company before it becomes obvious and why is being early so much harder than being right? In this episode, I talk with Jonathan Lacoste, Founder and General Partner of Space VC, about investing at the moment when ideas are still non-consensus. Jonathan explains the difference between deep tech and frontier tech, why founder migration is the strongest signal of emerging opportunity, and how pre-seed investors create alpha by backing contrarian founders before markets agree. We discuss how grit and mission outperform IQ, why concentration beats diversification in early-stage portfolios, and how patience compounds into an edge over time.

Highlights:

• The difference between deep tech, frontier tech, and “just tech”
• Why founder migration predicts where value is forming
• Investing before consensus vs. competing after consensus
• Why pre-seed alpha comes from people, not theses
• How grit, obsession, and mission predict founder success
• Why concentration works better than diversification at pre-seed
• How Jonathan evaluates first-time founders before companies exist
• Lessons from building and selling his own startup
• Why hardware and industrial tech are becoming venture-scale
• How patience and restraint compound into long-term advantage
