David’s Story

From Apple Reseller to Leadership Framework.

David Sun founded one of the world’s largest Apple resellers and helped establish Apple’s first retail presence in Hong Kong — navigating the East/West business culture divide at the highest levels of global commerce. He served on Apple Advisory Boards during the company’s most transformative years.

He is a YPO Founding and Lifetime Member, a White House Award recipient, and a certified TTI Talent Insights coach. His work spans four decades, four continents, and every business cycle of the modern era.

The Sponge Leader™ is not a theory assembled in a classroom. It is the distillation of what actually separates leaders who remain relevant from those who become obsolete — discovered through real failure, real growth, and real responsibility at scale.

Today David works exclusively with senior leaders, executives, and high-growth entrepreneurs in long-term retained coaching relationships anchored by structured diagnostics and the Leadership OS framework.
