On The Lookout For

As a passionate observer and participant in the local tech ecosystem, I am on a quest to unearth the most meaningful stories that propel large-scale dealmaking and drive the region’s rapid modernization. 

I believe that behind every successful deal and transformative investment lies a narrative that captures the essence of innovation, resilience, and impact. These stories not only showcase the potential of ASEAN’s tech landscape but also inspire others to participate.

I aim to shed light on the companies, entrepreneurs, and investors who are spearheading breakthrough solutions and catalyzing progress in sectors ranging from fintech and e-commerce to healthcare and sustainability and beyond. Through their ideas, disruptive technologies, and unwavering determination, they are reshaping industries, empowering communities, and propelling emerging markets like Indonesia forward.
