Just watched Mike Krieger (Instagram co-founder, now CPO at Anthropic) drop a 30-min masterclass on product thinking, and it’s gold for any founder or PM building in 2025. Here are my key takeaways, timestamped and with real talk 👇 🔹 (00:00) “When to shut down your startup” Most founders drag it out. Mike’s take? If you’ve tried all the levers, move on. Investors respect self-awareness. Artifact’s shutdown wasn’t failure, it was iteration fuel for Claude. (04:06) “Why Instagram worked” In 2010, most people thought mobile apps were toys. But IG nailed timing + simplicity. No filters, no stories, just fast photo sharing. That bet on the mobile wave led to 1M users in 2 months. (12:03) “What killed Artifact” They had insane recsys tech, but forgot that early users need instant value. People don’t want to “train” an app. Lesson: your first session UX should feel like magic, not onboarding homework. (18:15) “How they build Claude” Krieger talks about Claude’s vibe. Not just accuracy, but tone, flow, emotional intelligence. AI products aren’t just logic trees, they’re emotional experiences. Huge shift in product design thinking. (24:40) “Where AI is going” He sees the LLM race consolidating fast, only a few model labs will survive due to compute burn. But product layers? Wild open space. It’s the 2007 iPhone moment for AI UX. If you’re building in AI, media, or consumer tech. This is a must-watch. 🎥 Full talk (30 mins): My favorite line: “Great products feel right, even before you explain them.”
