Jason Marburger / Fireball Tooldiscussed

Caroline's second skilled-trades pick, answering a standing question from earlier conversations: welding requires certifications but isn't a licensed trade. Jason has built Fireball Tool into a highly trusted brand with welders, fabricators and DIY learners — problem-solving education, tool design and shop-setup content around the metal-fabrication ecosystem, where he demos his own proprietary products (welding fixtures, tables, squares) in real working environments: a natural educate→use→sell flywheel. It already looks like a proper global business — US and EU customer service — while the YouTube keeps scaling ('people show up in mass to watch these videos'). The macro thesis: tradespeople and fabrication are taking off as AI data centers get built. Warm paths exist: Megan noted portfolio creator Jonathan (Katz-Moses) follows him ('so classic'), and Eddie is already getting looped in via one of his customer-service-play contacts and will bring Caroline along. The discussion closed with intro hygiene on asking portfolio creators for connections: fine to float, but try other routes first — bothering portfolio creators is the last-ditch move.
