In today's episode of U.S. Manufacturing Today, Matt Horine interviews Spencer Penn, Co-founder and CEO of LightSource, an AI-powered procurement platform for direct materials. Penn recounts leading sourcing for Tesla’s Model 3 scale-up and seeing $30B of parts managed via spreadsheets and email, inspiring him to found LightSource in 2021. The conversation argues procurement is strategically critical yet undertooled compared with sales, with incentives and visibility lagging despite large P&L impact. Penn describes how AI can improve supplier discovery, should-cost estimation, negotiation support, ongoing price monitoring, and faster deployment via automated data ingestion. LightSource customers reportedly cut RFX cycle times 25–60%, improve supplier experience, and reduce cost creep; one A/B test showed 25% faster cycles and 47% lower cost creep. They discuss dual sourcing, nearshoring/onshoring realities, China’s industrial base, and advice for leaders to experiment with tools like Claude/Claude Code.
