Reinventing Email with AI - This YC Startup Might Replace Gmail

What if your inbox didn’t just organize itself — it acted on your behalf? Nizar Abi Zaher, founder of Zero, is building the AI-native email client that reads, replies, filters, and organizes without you lifting a finger. In this tactical, fast-paced conversation, we explore his path from Cal.com engineer to YC founder — and how he's going head-to-head with Superhuman. From open-source strategies to voice-powered inboxes, Nizar breaks down how Zero is redefining email — and what it takes to ship fast, build in public, and stay top of mind. In this episode, you’ll learn: • Why Zero was built around what people hate • How YC pushed them to launch before they were ready • How being open-source accelerates product velocity • What Superhuman got wrong — and what Zero does better • How social presence became their biggest moat • What email looks like in 5 years (hint: voice + AI agents) 📌 Watch now and subscribe for more smart, fast, founder-first interviews.
