Noah Shinn - Building Instinct: The Personal Agent - [Invest Like the Best, EP.493]
Invest Like the Best with Patrick O'Shaughnessy
Proactive Safety And Systemic Learning
Noah Shinn describes early mistakes, proactive safeguards, user data control, and systems that intercept hallucinations and risky agent actions.
My guest today is Noah Shinn. Noah is the founder of Instinct, a personal assistant that you text, call, or email the same way you would a person. It has its own phone and its own computer, and it can do almost anything on your behalf that you would do yourself online. Instinct is about a year old, still invite-only, and growing roughly 10% day over day without any marketing spend.
We discuss the surprising ways people are already using Instinct, the trusted network that lets two people's agents coordinate directly, and what Noah has learned about how long it takes users to trust an agent with their credit card, inbox, and calendar. He explains why he refuses to build an ad model and why he believes a personal agent should never influence users against their own interests.
We also cover the take rate model behind the more than $1 billion a year now flowing through the platform, how travel and food delivery businesses should prepare for a world of agents, why he spends 40% of his time thinking about compute, and why he believes all of software will eventually collapse into one simple interface.
Please enjoy my conversation with Noah Shinn.
