Tether Invests in AIsa to Expand AI-Agent Payments and API Access

Announced on October 15, 2026, the investment amount and equity stake were not disclosed. AIsa allows developers to connect AI agents with multiple digital services and pay for their usage through traditional currencies or stablecoins. The deal also expands Tether's involvement in AI infrastructure and automated payments.

How Does AIsa's Platform Work?

AIsa provides a single access point for AI agents to use external data, AI models, application programming interfaces (APIs), software tools, and computing resources. Instead of creating separate accounts or managing individual subscriptions for each service, developers can connect their agents through one credential.

The platform uses a usage-based payment model, allowing agents to pay for individual service calls rather than maintaining separate subscriptions for every provider. Payments can be made in fiat currencies or stablecoins, depending on the supported payment arrangements.

AIsa Reports More Than 250,000 AI Agents

According to company-reported figures, AIsa has more than 250,000 agents using its platform and has processed over 100 million transactions. Its network also provides access to more than 5,000 APIs, skills, and AI models.

These figures were reported by the company and have not been independently verified in the investment announcement. The companies have also not disclosed the total payment value processed through the platform or the proportion of transactions settled in stablecoins.

AIsa's model allows service providers to make their digital resources available to automated workflows, while businesses can purchase services as needed. This could help companies reduce the need to manage multiple subscriptions when deploying AI agents for research, analysis, and other business tasks.

AIsa's Previous Funding and Investors

AIsa previously raised funding from technology companies, financial institutions, and venture capital investors. According to the company's October 15 announcement, its seed extension round included Tether and HIVEN as strategic investors, bringing its total funding to more than $9 million.

Other investors named in the announcement include Alibaba, Tribe Capital, Sumitomo Corporation, Draper Associates, and Saison Capital.

The latest investment adds another strategic backer as AIsa develops its platform for enterprise AI agents. The companies have not disclosed the individual investment amounts contributed by Tether or HIVEN.
