In this candid interview with Silicon Valley Girl, Replit CEO and founder Amjad Masad lays out a provocative thesis: AI is about to collapse the time and capital required to build a billion-dollar company from years to days. Amjad argues that the traditional startup playbook---raising venture capital, hiring large engineering teams, and spending years iterating---is being fundamentally disrupted by AI-assisted development platforms that let solo founders and tiny teams ship production-grade software at unprecedented speed. He shares his philosophy on why the future belongs to 'billion-dollar one-person companies,' how Replit is architecting its platform to make that possible, and what the consolidation of AI models and tooling means for builders in 2026 and beyond. Essential viewing for founders, developers, and anyone trying to understand the economics of building software in the age of AI.
