Full-Stack AI, Zapier MCP & Limitless Pendant | $10 M Boring Tunnels

This week on Built 2 Scale: Scott loses his brand-new Limitless pendant (turns out “Find My” isn’t included), Matt explains why Zapier’s new MCP server might let interns run the office, and the guys dissect YC’s “full-stack AI” memo. They roast Google’s Gemini branding fumble, cheer OpenAI’s Sheryl-Sandberg-style hire, and marvel at Elon’s autonomous boring machine that digs tunnels for 1 % of Melbourne-Metro costs. Plus: stealth AR teleprompter glasses, trillion-dollar TAM math, and a $10 K “Founder OnlyFans” riff. Quick hits, sharp insights, and robot-enhanced banter—tune in or get left behind!
