Podcast interview

Spencer Penn, CEO of LightSource.ai, discusses how his experience at Tesla revealed a critical gap in automotive procurement: the reliance on outdated spreadsheets for multi-billion-dollar sourcing. LightSource.ai addresses this by utilizing “agentic AI” to automate the “spec-to-scale” process. By transforming procurement from a tactical execution to a strategic “system of record,” the platform allows professionals to focus on high-value decision-making, significantly reducing sourcing cycles and enhancing supply chain resilience in a volatile global market.
