Hustle Fund's Elizabeth Yin: Launch-Day Spikes Aren't Run Rate — Only Paying Users Are Customers

dunkhippo33 · x · 2026-10-15

Elizabeth Yin, co-founder of Hustle Fund, warns founders against extrapolating run rate from launch-day customer counts. Traffic spikes aren't run rate; it should be your 12-month average linearized, not your best days.

She also draws a hard line on what counts as a customer: only someone who has actually handed over money. Everything else, she says, is "a vibe at best, and a lie at worst."
