Financial infrastructure for the agent economy
Autonomous agents and the businesses that serve them lack seamless ways to hold, spend, and accept money without human involvement.
Sponge provides financial infrastructure—bank accounts, cards, and crypto rails—that lets agents transact autonomously and enables businesses to onboard and accept agent payments with minimal effort.
Autonomous AI agents and businesses that want to sell services directly to those agents.
