Just watched Mike Krieger (Instagram co-founder, now CPO at Anthropic) drop a 30-min masterclass on product thinking, and itโs gold for any founder or PM building in 2025. Here are my key takeaways, timestamped and with real talk ๐ ๐น (00:00) โWhen to shut down your startupโ Most founders drag it out. Mikeโs take? If youโve tried all the levers, move on. Investors respect self-awareness. Artifactโs shutdown wasnโt failure, it was iteration fuel for Claude. (04:06) โWhy Instagram workedโ 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) โWhat killed Artifactโ They had insane recsys tech, but forgot that early users need instant value. People donโt want to โtrainโ an app. Lesson: your first session UX should feel like magic, not onboarding homework. (18:15) โHow they build Claudeโ Krieger talks about Claudeโs vibe. Not just accuracy, but tone, flow, emotional intelligence. AI products arenโt just logic trees, theyโre emotional experiences. Huge shift in product design thinking. (24:40) โWhere AI is goingโ He sees the LLM race consolidating fast, only a few model labs will survive due to compute burn. But product layers? Wild open space. Itโs the 2007 iPhone moment for AI UX. If youโre building in AI, media, or consumer tech. This is a must-watch. ๐ฅ Full talk (30 mins): My favorite line: โGreat products feel right, even before you explain them.โ
