Fred Ehrsam co-founded Coinbase before becoming a full-time investor at Paradigm, giving him rare hands-on experience building one of crypto's most important companies from niche hobby to mainstream business. He focuses on frontier areas of crypto where conventional metrics don't exist, combining deep technical diligence with long-form public writing that attracts technical founders and positions him as a bridge between crypto natives and mainstream audiences.

• A strong thesis that medical treatments will evolve into mass-market human enhancement products. He views current weight loss drugs as just the beginning of a trillion-dollar shift where therapies initially designed for the sick are eventually used to optimize healthy people, similar to his investment in companies working on longevity and cellular rejuvenation.
• Deep interest in brain-computer interfaces and neurotechnology to improve daily life. He is actively building and investing in hardware that uses non-invasive methods, such as ultrasound, to modulate brain activity, allowing users to control their mental states for better sleep, focus, or mood regulation.
• Conviction that stablecoins and blockchain technology represent a generational shift in global finance. He argues that this infrastructure allows for a speed and global scale that traditional systems cannot match, creating a barbell effect that serves both high-end investors in developed nations and under-served populations in developing economies.
• Enthusiasm for the application of artificial intelligence to hard sciences, particularly biology and chemistry. He highlights how new computational models are achieving state-of-the-art results in molecular structure prediction and antibody discovery, effectively turning concepts that used to be science fiction into functional tools for drug design.
• Support for ambitious "hard tech" solutions to systemic problems, such as energy abundance and scientific research. He promotes nuclear energy as a critical area for development and has expressed curiosity about decentralized science, looking for efficient ways to fund and organize research outside of traditional academic structures.
• Preference for founders who articulate a distinctive, positive vision of the future rather than just critiquing existing systems. In terms of team building, he values deep intellectual curiosity, suggesting that a great way to evaluate talent is to have a candidate explain an arbitrary topic in extreme detail to gauge their depth of understanding.
