Nat Greene is a co-founder and CEO of the consulting firm Stroud International. He has practiced technical problem solving as a consultant for eighteen years, solving dozens of impossible technical problems for over fifty clients on five continents.

Nat is a business leader, author, and champion of great problem-solving. He helps smart people make radically better decisions and all his activities and interests are tied to this mission. Nat helped found and run Stroud international and is the author of two books. Wedged is a look into some of the drivers behind political dysfunction in the US and Stop Guessing explores the behaviors of great problem-solvers.

Nat's upbringing ingrained an intense drive to help people develop an Abundant Thinking mindset, understanding that more is always possible. Nat was born and raised in Hong Kong, during a period of immense growth in social mobility, influenced by not only dreamers but also by those looking to push educational and professional boundaries. His father, a professor of material science, taught him about problem-solving at a young age by taking him around the city and helping him to explore what was broken and why.

Nat remains inspired by the belief that anything is possible and has chosen to dedicate his life to productively challenging the conventional limits of the status quo. He takes an approach that is hands-on, data-driven, and follows a rigorous process to break constraints. He always delivers results; a model Stroud follows. Nat's curiosity, determination, and passion extends beyond his work to every corner of his life. He enjoys spending time with his family, and learns a great deal from his children, who are not bound by the same pre-conceived notions and experiences that constrain many adults. Nat, his wife, and four children reside in Marblehead, Massachusetts by the ocean, a symbol of infinite possibility that inspires him.

Nat has a Masters of Engineering from Oxford University and studied design, manufacturing and management at Cambridge University, in addition to executive education coursework in Harvard Business School's Owner/President Management program."
