Paul Buchheit
Paul Buchheit, often called PB in Paul Buchheit on Gmail, Google, FriendFeed, and Startup Judgment, is presented as the creator of Gmail, early Google employee number 23, FriendFeed founder, former Y Combinator partner, and angel investor. The episode traces him from a tool-heavy childhood and early C programming through Intel, Google, FriendFeed, Meta/Facebook, YC, and startup investing.
His strongest wiki role is as a product-engineering judgment case. Gmail shows his preference for Fast Feedback Loops: build a working prototype, expose it to real internal users, watch what they ask for, ask whether they are happy, and talk to the unhappy ones. The same pattern appears in his startup advice: founder conviction is weaker than Customer Pull, Pre-Product Selling, payment, LOIs, or other behavior that costs the customer something.
PB also adds an investor-judgment branch through Outlier-Driven Angel Investing. He says startup returns are driven by rare huge companies, that founder quality is the dominant variable, and that his most common investing mistake is wanting an idea to work even when the founder signal is weak. In the episode, DoorDash is his strongest disclosed financial angel outcome, while Stripe is mentioned as a company that might become larger.
