CEO & Founder

Harry Zeng

Software engineer turned wellness entrepreneur.

Harry founded Haoyao Corp after experiencing firsthand how transformative consistent sauna sessions could be — not just physically, but mentally. With a background in full-stack engineering and e-commerce, he bridges the gap between cutting-edge product design and the customers who use it every day.

He oversees the company's overall strategy, product direction, and brand vision — driven by a belief that premium wellness technology should be available to every household, not just luxury spas.
