When Connection Still Requires Starting Again

What if Southeast Asia’s biggest companies make the region look easier to build in than it really is? Episode 25 asks whether Southeast Asia has developed a genuinely regional innovation system, or whether eleven distinct national ecosystems are still being connected largely by a handful of platforms, investors and financial centres. The same app may work seamlessly across several countries, but behind the screen are different relationships, regulations, payment systems and customer behaviours that companies repeatedly have to learn.

Using the S² Bureau’s Ecosystem Momentum Framework, Neo examines how capital, company building, talent, policy and customer demand connect across the region. Grab demonstrates meaningful multi-country demand, while GoTo shows how enormous scale can still remain overwhelmingly domestic. Singapore connects much of the region to capital, yet later-stage funding becomes harder to access, while local knowledge and trust often refuse to travel as easily as money or technology.

The Regional Illusion finds a Southeast Asia with real shared capabilities, but selective momentum. Companies cross borders, experienced founders recycle knowledge, governments are building connections and regional infrastructure is improving. What remains uneven is whether the next company can actually inherit those advantages, or whether every founder crossing a border still has to assemble much of the system again for themselves.
