This is the best time to build a startup ever. To young people thinking whether to build something: Start Now.This week on the EU-Startups Podcast, Marcin Lewandowski sits down with Laura Modiano (Startups EMEA at OpenAI) to turn her “love letter to European founders” into a build-now playbook.We break down OpenAI’s latest platform updates—Apps in ChatGPT + Apps SDK (a brand-new distribution channel), AgentKit (agents that actually do), Codex (GA) for developer speed, Sora 2 / Sora 2 Pro via API for high-ROI video, and GPT-5-pro for higher-stakes reasoning—into concrete steps founders can run today.You’ll learn:– The fastest path from idea → prototype using OpenAI’s stack (weekend-level speed)– Apps in ChatGPT: how discovery + monetization change—and what founders should prep before day one– Where AgentKit beats basic API calls (state, tools, guardrails → outcomes)– How to fold Codex (GA) into your PR flow without slowing teams– Sora 2: responsible, high-ROI uses that move real metrics– GPT-5-pro vs. cheaper models: a practical decision rubric (stakes, accuracy, latency, cost)Takeaways:– Speed is a moat: scaffold with GPT-5-pro, then optimize to cheaper models.– Don’t “add AI”—remove steps: redesign the workflow; kill clicks, not add them.– Apps in ChatGPT = new distribution: 800M weekly users; EU/UK—prep your app listing, onboarding, and pricing now.– Agents vs. endpoints: with AgentKit, combine state + tools + guardrails to deliver outcomes, not demos.– Codex (GA) ≠ novelty: pair-programming, repo refactors, doc hygiene—without slowing PR velocity.– Sora 2: use where dynamic video outperforms static—product demos, instructionals, simulations.– Europe’s edge: talent density + research depth; the bottleneck is belief + shipping cadence, not brains.Chapters:If you haven't already....
