Summary
Tether has invested in San Francisco-based artificial intelligence startup AIsa alongside HIVEN, completing a seed extension round that brings the company's reported total funding above $9 million. AIsa announced the round on October 15, confirming that the two new investors joined existing backers including Alibaba, Tribe Capital, Sumitomo Corporation, Draper Associates and Saison Capital. Tether Capital, the investment arm of Tether based in El Salvador, separately confirmed its participation, describing the investment as part of its work on AI-powered payments and programmable money. Neither company disclosed the amount Tether contributed, AIsa's valuation or the ownership stake acquired.
AIsa had previously reported $6.5 million in cumulative funding in July, when Alibaba and Tribe Capital co-led its earlier seed round. The difference between the two disclosed totals implies more than $2.5 million added since July, but AIsa has not disclosed individual contributions from Tether and HIVEN, and the company has not announced a new valuation or published the terms of the latest financing.
AIsa's platform allows AI agents to find and purchase access to external data, AI models, application programming interfaces and business software through a single interface, replacing separate accounts and subscriptions for each provider. According to AIsa, the system includes usage tracking, billing and settlement, along with controls for permissions, budgets and transaction approvals, and it provides audit trails. Businesses can set spending limits before agents make purchases. AIsa said payments can use conventional currencies or stablecoins depending on the service; Tether's statement described stablecoins as one option and did not say all transactions would settle in USDT. Jordan Liu, AIsa's founder and CEO, said enterprise AI agents require "trusted information, useful tools and a governed way to transact."
Tether CEO Paolo Ardoino linked the investment to the growing use of AI systems that act on behalf of individuals and businesses, arguing that users need control over what automated agents spend. Tether said AIsa supports more than 250,000 operating agents, has processed over 100 million transactions, and provides access to more than 5,000 APIs, software tools and models through a single account. These figures were presented by the investor and have not been independently audited. AIsa's July statement had reported more than 50,000 registered agents, but the two counts use different descriptions and do not establish an exact growth rate.
AIsa said it has begun pilot programs with enterprises exploring uses in financial intelligence, market research, supply-chain management and commerce, though it did not identify pilot partners or disclose contract values. Its stated next priorities include expanding its global resource network, strengthening enterprise spending controls and developing transaction infrastructure. Tether has pursued related AI and payments investments, including its participation in NEURA Robotics' financing of up to $1.4 billion reported in June, and backing of Oobit's AI payment cards in May. Tether reported $1.5 billion in second-quarter 2026 profit in July, with assets of approximately $187.7 billion at the end of June, though those figures do not indicate how much capital went to AIsa.
