Justin M. Lewis

Justin M. Lewis is a Marine Corps veteran, writer, and entrepreneur focused on leadership, creativity, and the future of intelligent systems. He is a cofounder of Instrument, which he helped build over nearly two decades before the company was acquired by MDC Partners, later rebranded as Stagwell. During that period, he worked across the network to scale his beliefs around culture, leadership, and effectiveness beyond a single agency. Today, Justin writes and thinks publicly, is an aspiring race car driver, and is actively working to help shape the future of artificial intelligence—focused on trust, traceability, and human-centered decision-making.
