hub vs hub
┌─ generated from funding, org, model, compute, and overlap signals ─────────────────────────────── ┐
Boston has more capital; Seoul has the stronger notable-model count.
Boston's biggest carrier is OpenEvidence: $700M (34.6% of tracked side funding). Seoul's biggest carrier is Rebellions: $850M (50.1% of tracked side funding).
The org treemap is shown because both sides have enough funded orgs for area to mean something.
Funding is HQ-based and limited to AI-native orgs. Compute is counted by datacenter location, so it can disagree with headquarters funding.
