Scott Leff is the founder of LEF, a B2B content marketing agency that partners with global consulting firms and enterprise organizations to create high-impact content across written, design, and video formats.

Based in Chicago, with a distributed team across Europe, Scott has spent over 16 years building and scaling LEF from a solo freelance operation into a 28-person agency serving long-term, global clients.

Before starting LEF, Scott began his career in business publishing at McKinsey & Company, where he served as Managing Editor of the McKinsey Quarterly. He later worked on Chicago’s Olympic bid before transitioning into entrepreneurship — a move that started without a clear plan but evolved through experimentation, adaptability, and a willingness to say yes and figure things out.

Scott is passionate about the craft of storytelling, the evolution of content in business, and building organizations that grow sustainably over time. Outside of work, he’s deeply connected to music — both as a listener and creator — and produces intimate live concert experiences inspired by formats like Tiny Desk.

He believes that entrepreneurship is less about having everything figured out and more about developing the resilience and curiosity to navigate uncertainty, one decision at a time.
