THE PROCUREMENT INTERVIEW
For many procurement professionals, the daily reality of managing multi-billiondollar supply chains still looks like a digital version of operations in the 1990s. Despite the rapid evolution of global trade, a staggering 75 % of procurement teams still rely on a combination of fragmented spreadsheets and endless email chains to manage direct materials.
Spencer Penn, Co-Founder and CEO of LightSource, knows this alarming status quo better than most. Before founding the AI-powered strategic sourcing platform, Spencer was a leader at Tesla, where he helped launch the Model 3 programme. It was there, amidst the pressure of scaling from 1,000 vehicles per week to millions, that he witnessed the breaking point of traditional procurement.
“ One of the big challenges that we faced was that we were sourcing 30 billion of direct materials on Excel spreadsheets and emails,” Spencer recalls.“ I sourced millions of parts for the Model 3 with email chains that contained hundreds of messages. As we neared production, I knew there had to be a better way.”
The missing system of record In the modern manufacturing landscape, the distinction between direct and indirect procurement is often where the digital transformation journey stutters. While indirect spend, the“ tail spend” of office supplies and travel, has seen significant innovation, direct materials remain trapped in manual processes.

Spencer describes this disparity through a vivid analogy:“ The way I describe it is that indirect procurement is like UPS when it picks up a package. It has to route it and drop it off. It’ s a one-time flow and it’ s done. And then direct materials are much more like the plumbing in a building. You have to set it up right.”
For companies like Tesla, or LightSource’ s current clients such as Yum! Brands and Bombardier, the“ plumbing” of direct materials is the lifeblood of the business. Yet, while sales teams have Salesforce and engineers have CAD, procurement has lacked a unified system of record.“ LightSource is akin to how Salesforce works for a sales team,” Spencer explains.“ Salesforce helps sales teams find customers and sell to them and then procurement is the same thing in reverse. We’ re finding vendors and we’ re buying from them. So instead of a sales motion, we’ re running a sourcing motion.”
