About

Han Sunghee

CEO of Simplifier · Hands-on Startup Coach

Han Sunghee, CEO of Simplifier

I build products. I started at NAVER, then worked at Samsung Electronics, Yogiyo, and Bithumb, growing from individual contributor to team lead, PM, CPO, and COO. I was there when a company grew from 50 people to 1,000, and when a 200-person organization reached KRW 1 trillion in revenue.

Today, as CEO of Simplifier, I work on site with startups and build products alongside them. I chose not to be an advisor who gives advice and leaves. I work next to founders and their teams and execute with them.

My talks and workshops come from that work. I bring the problem that stalled yesterday's meeting and the call I got wrong this quarter. So cases come before theory, and every session ends with hands-on practice.

Interview

Our leaders were going through a lot of confusion after a change in company strategy. The talk helped them see why that confusion was happening, and that they should treat it as a shift in the landscape, not a crisis, and turn it into a chance to lead. It was exactly the talk we needed at that moment.
