Carl Pei describes how his interest in Apple products led him from building a Meizu fan community to working in China and helping start OnePlus. At Nothing, he applied lessons from OnePlus but faced factory skepticism, so the company began with earbuds; after quality problems left most of the first batch unable to charge, engineers worked alongside the factory to fix production. He emphasizes that hardware startups need to survive long enough to build volume, trusted manufacturing relationships, and stronger teams, and explains how Nothing’s design focus and Glyph Interface aim to make its products recognizable and encourage more mindful phone use. His advice is to sequence ambitious hardware plans by earning credibility with a smaller product before tackling a smartphone.

Zach Sims traces Codecademy’s path from early experiments and work at GroupMe to finding a way to teach programming that he and his co-founder needed themselves. He describes how setbacks, blunt feedback, and a last-minute pivot during Y Combinator helped them discover a product people wanted. The talk argues that founders should start before they feel ready, learn by building, and work on problems they care about. Sims also emphasizes that startup success is uneven and that persistence matters through both growth and setbacks.
