01Payment Processors
What they built: sophisticated payment infrastructure for human-initiated transactions. SDKs, checkout flows, settlement, basic dispute response. What's missing: agent-to-agent orchestration with policy, learning that persists across organizations, autonomous dispute resolution with graduated controls. Their APIs assume a user, a session, a checkout flow.
02Blockchain & DeFi
What they built: programmable settlement with smart-contract logic and on-chain auditability. What's missing: authorization policy, compliance pre-checks, dispute reasoning, federated learning, integration with the regulated payment rails most enterprises must still operate on. Settlement is one stage of a multi-stage operation.
03AI Agent Platforms
What they built: sophisticated agent orchestration, tool use, browser automation, reasoning chains. What's missing: payments DNA. Settlement mechanics, escrow, chargeback handling, multi-jurisdictional compliance, the operational scar tissue of 27 years in regulated payments. Agent platforms are excellent at the reasoning layer and have nothing underneath it.
04Federated Learning
What they built: privacy-preserving ML techniques. Differential privacy, secure aggregation, federated optimization. What's missing: production deployment in regulated payments, a closed loop from operational outcomes back into decisions, multi-jurisdictional real-world validation at commercial scale. Federated learning has been a research project, not a production system for autonomous commerce.
05Dispute Automation
What they built: template-based response drafting, evidence aggregation, integration with one or two card networks. What's missing: federated learning across organizations, graduated autonomy with strict gating, integration with the upstream payment infrastructure that originates the dispute in the first place. They automate one piece of the dispute lifecycle, not the lifecycle itself.
