At the ASEAN Startup Connect Summit, funded by the Japan-ASEAN Integration Fund, eight national delegations and Japan sat down to find common ground on startup ecosystems. The challenge was not information. Every delegation had data, case studies and positions ready. The challenge was the unspoken: what each delegation thought but would not say to the others.
Optomize, the AI coach built on the 5 Spheres of Empathy method, was used to power the facilitation across the summit. It ran what we call the Unsaid Protocol: a structured process for surfacing the assumptions, hesitations and unvoiced concerns that sit underneath any negotiation or collaboration.
The method works in three moves. First, participants map what they believe the other side is thinking but not saying. Second, they map what they themselves are not saying and why. Third, the facilitator brings both maps into the open and uses them as the starting point for real conversation, not polished positions.
This is the third and fourth spheres of empathy in practice. You are not trying to guess what the other person feels. You are building a working model of what they see, what they want, and what they are protecting, then testing that model against reality. When delegations saw their own unspoken assumptions named clearly, the conversation shifted from diplomatic posture to honest problem-solving.
The white paper documents how this played out across the summit, including the specific friction points it surfaced and the outcomes that followed. It is one of the clearest examples of the 5 Spheres method applied at scale, in a room where the stakes and the silences were both real.
