Mr. Yap Seong Fatt & Mrs. Yap (Mdm. Tan Kai Jong) — Founders
Where it began
Yap Seong Fatt didn’t get into a local university. Many would’ve seen that as the end of the road—but not him. With quiet courage and the support of his brother, a door-to-door ice cream seller in Melaka, he was handed RM300. Just enough for a one-way flight and the first semester of an accountancy degree in New Zealand. In a foreign land, he didn’t just earn a degree—he found his purpose and his life partner, Mdm. Tan Kai Jong (Mrs. Yap).
RM300 — a one-way flight and one semester of an accountancy degree — the entire starting capital of what YYC would become.
The two returned to Malaysia with a shared vision: to start an accounting firm that truly served entrepreneurs. That was the birth of YYC. A few years in, Mr. Yeo Wee Thow joined forces with Mr. Yap. Together, the duo built one of Malaysia’s earliest and most trusted accounting firms—brick by brick, client by client.

Growth
In 2024, YYC crossed a major milestone — surpassing 1,000 talents. A proud moment. A dream realised. Our growth has been backed by bold strategic moves—first with OCBC, and now with SeaTown Holdings, an indirect wholly-owned subsidiary of Temasek. Their belief in our vision fuels us to go further, faster, and with even greater purpose.
With the funding from SeaTown, we expanded aggressively through strategic acquisitions across Malaysia, Singapore and Hong Kong. These moves strengthened our regional presence and technology capabilities to serve entrepreneurs better than ever.
But after reaching that peak, another thought emerged: “What about the next 30, 50, even 100 years?” That question led to deep reflection. And from that reflection, a new vision was born: YYC Vision 2.0.
