Very few people on the planet have built products used by 2+ billion people. Today’s guest is Uri Levine — co-founder of Waze (acquired by Google) and early founder of Moovit (acquired for $1B+), and the author of “Fall in Love with the Problem, Not the Solution.”In this episode, Uri breaks down the real mechanics behind breakout products—starting with the problem, not the tech. We go deep on:- The real “Eureka moment” that led to Waze (and why traffic was only the trigger)-Why certainty (ETA accuracy) beat “saving time” as the true value prop- How to validate a problem properly (including the “talk to 100 people” rule)- Why retention is the only real metric of product-market fit- The leadership decisions that separate companies that scale from those that stall- – Why simplicity wins—and how great products become “embarrassingly simple”Quick note: you may notice my voice is a bit hoarse in this episode—I was losing my voice that day, but I didn’t want to miss the opportunity to sit down with Uri. Thank you for bearing with me.If you’re a founder, product manager, or builder, this conversation is a masterclass.Subscribe to my newsletter: https://www.mahmoudkhodor.comUri's LinkedIn: https://www.linkedin.com/in/uri-levine/Uri's book: https://urilevine.com/book/Concise Chapters / Timeline00:00 – The traffic moment that sparked Waze01:25 – Why founders start: emotional problems, not ideas03:00 – From idea to company: how Waze really began05:00 – Crowdsourcing as a moat (and how trust was built)07:30 – The real value of Waze: certainty over speed09:00 – How to validate a problem before building12:00 – “Fall in love with the problem, not the solution”18:00 – Startups are a journey of failure (and iteration)23:30 – Leadership lessons: hiring, firing, and hard decisions31:45 – Product-market fit explained: retention is the metric44:00 – Simplicity wins: why fewer features beat better tech58:45 – When startups die: scaling before the product is ready01:09:20 – Acquisition lessons: what success actually feels like01:12:10 – Final principles: good enough, problem-first, simplicity
