HOW TO MAKE A VIRAL LAUNCH VIDEO

Six founders who went viral share how they turned product launches into millions of views and instant waitlists. The pattern across all winners? Show, don't tell, make viewers say "I can't believe this didn't exist," and treat launches as weapons, not your end goal. Silicon Valley now treats B2B software like entertainment products because everyone's fighting for attention. Early investors literally write checks based on viral tweets - social media has become social currency.

4 AI WORKFLOWS TO HELP YOU SHIP BETTER PRODUCTS

This post drops four prompts that actually move the needle for product teams. The first prompt uses computer control models to crawl your actual product and build a feature taxonomy from the user's perspective. The second prompt turns boring product strategies into narratives that sell your vision. The third prompt frames every PRD within your overall strategy so initiatives aren't just random features, but steps toward your vision. The fourth prompt evaluates your plans like a brutally honest CPO who'll call out second-order effects and hidden risks. These aren't just prompts, but a framework for decomposing tasks and bringing expertise to get outputs worth shipping.

THE CASE FOR STAYING PUT

After three years in one apartment, this author discovered what digital nomads miss: real connection only comes from dealing with a place's boring parts. He spent years hopping between cities, thinking each Instagram-worthy location would make him happy. However, constant movement meant never belonging anywhere. The case for staying put is simple - you can't build meaningful relationships or impact when you're always leaving. The daily annoyances, the negotiations with neighbors, the commitment to local problems - that's what creates actual community.

RAG IS DEAD, CONTEXT ENGINEERING IS KING

Chroma's founder says RAG is dead because it bundles three concepts poorly - the real job is context engineering, figuring out what belongs in the context window for each LLM generation. The best teams now use a two-stage approach: first-stage retrieval (vector search, text search, and metadata) culls 10,000 candidates down to 300, then LLMs re-rank those to the final 20-30. This matters because context rot is real - despite perfect needle-in-haystack marketing, models degrade as you add tokens. The future looks radically different: models will stay in latent space without converting back to text and retrieve continuously during generation instead of once at the start. What we call "memory" is just context engineering with better branding.
