"In a start-up company, you basically throw out all assumptions every three weeks"
About this Quote
Phelps is an educator, which sharpens the subtext. He’s not romanticizing chaos for its own sake; he’s describing a learning environment at maximum intensity. In a classroom, assumptions can linger for a semester. In a startup, feedback is immediate, public, and often brutal: a feature ships, users ignore it; a marketing angle lands flat; a competitor changes the rules; the runway shrinks. “Every three weeks” isn’t a literal sprint calendar so much as a tempo-a warning that the half-life of belief is short when you’re building in uncertainty.
The specific intent reads like a corrective to managerial theater. Startups love to borrow the language of strategy, roadmaps, and “vision” to sound legible to investors and recruits. Phelps’s phrasing cuts through that performance and quietly recommends intellectual humility as the real advantage. The best teams aren’t those with the most confident assumptions; they’re the ones that can discard them without ego, turning what looks like instability into a repeatable practice of adaptation.
