In this episode of the Marketing Roundtable, Brian Cosgrove connects with Sarathkumar Nallusamy, a supply chain data scientist and independent consultant who specializes in retail, e-commerce, and logistics. Together, they pull back the curtain on how backend systems, process engineering, and data models directly influence front-end business growth and marketing efficiency.
Sarathkumar brings a remarkably diverse technical background to the table. From mapping procurement strategies for a chemical plant at age 19 to navigating a comfortable, structured corporate life at IBM in Bangalore, his career has been defined by a constant push for greater scale. He shares the pivotal moment he decided to break out of his corporate comfort zone, move across the world to pursue a master’s degree at the University of Buffalo, and quickly found himself applying operations research to help the New York State Police predict and manage municipal scheduling.
As they dive into the core mechanics of decision science, Sarathkumar details his work with massive systems, including inventory and capacity time series forecasting for paper logistics giant WestRock and tracking 50,000 SKUs across 20 distinct fulfillment hubs for Staples. He breaks down how variables like geographical stock tracking directly impact web rankings and user experiences on the front end, demonstrating that a seamless digital interface is only as strong as the logistics network supporting it.
The Marketing Roundtable is available to watch on YouTube, or listen on Apple Music or Spotify.
“Analytics is actually asking the right questions, that's it. Everyone has the answer, AI has answers, everyone has answers, but are you asking the right questions?”
Sarathkumar shares how an innate curiosity and a willingness to simply talk to team members across different silos allowed him to unpack complex logistical networks. Whether visiting massive waste processing centers for paper manufacturing or building transportation cost models for a third-party logistics platform like Quiet Platforms, success came down to mapping the process flow.
Brian and Sarathkumar analyze the balance between raw technical execution and strategic business intuition. Sarathkumar discusses his intentional shift away from pure machine learning code production and toward high-level strategic alignment, demonstrating how a strong business game and systemic understanding can open doors at major organizations like Staples and tech startups alike.
The conversation also touches on the ongoing integration of AI within the data science landscape. Sarathkumar explains how the rail maintenance segment utilized computer vision and automated validation tasks, such as close to natural language processing work to sort through engineer text logs. He views AI as a powerful leveler that flattens technical barriers, allowing individuals with strong logical foundations to execute complex tasks. He challenges the next generation of professionals to use tools like OpenAI and Gemini not as an absolute authority, but as a sounding board to be constantly questioned and verified.
The conversation wraps up with a forward-looking view on the next decade of decision science. Sarathkumar highlights the massive intersection between digital infrastructure and energy distribution, illustrating how the principles of e-commerce supply chains are now being deployed to manage the enormous electrical loads required to power the AI revolution itself.
