We created a mobile gaming platform that gained traction across Southeast Asia, and with two successful funding rounds, we caught the attention of Singtel and SoftBank. That acquisition in 2012 was my first big milestone. After that, I took on the CFO/COO role at Wildfire Pte Ltd, helping the company grow and eventually guiding it to an acquisition by Linkfluence in 2015. But in 2025, I felt the urge to shift again.
