Tether Capital, Tether’s independent investment arm, announced a strategic investment in AIsa, a platform that enables AI agents to continuously access and pay for data, software tools, and computing resources.

As autonomous agents increasingly manage end-to-end workflows, legacy payment and subscription systems create significant operational friction. AIsa addresses this by offering a unified interface where developers can connect agents to more than 5,000 APIs, skills, and models through a single key, supporting per-call settlement in fiat currency or stablecoins within predefined corporate spending limits.

AIsa currently reports more than 250,000 deployed agents and more than 100 million processed transactions.
