SKN | Tether Capital Backs AIsa as AI Infrastructure Startup Raises More Than $9 Million

Key Points

• AIsa completed its seed extension round with Tether Capital and HIVEN joining as strategic investors, bringing the company’s total funding to more than $9 million.
• The San Francisco-based startup is developing infrastructure that connects enterprise AI agents with external data, models, APIs, software tools and industry services, while managing permissions, usage and payments.
• Tether’s investment aligns with its broader push into AI-powered payments and programmable money, following other investments exploring how machines can transact within predefined limits.

Tether is expanding its investment in artificial intelligence infrastructure through a strategic stake in AIsa, a startup developing systems that help enterprise AI agents access digital resources and manage transactions. The investment reflects growing interest in infrastructure that allows autonomous AI systems to interact with external services while operating within defined financial and operational controls.

AIsa announced that it had completed its seed extension round, with Tether Capital and HIVEN joining its investor base. The financing brings the company’s total funding to more than $9 million. Existing backers include Alibaba, Tribe Capital, Sumitomo Corporation, Draper Associates and Saison Capital, alongside other investors.

Jordan Liu, AIsa’s founder and chief executive, said the company aims to provide AI agents with access to trusted information, useful tools and governed transaction capabilities. Its infrastructure is designed to let enterprises control permissions, spending and transactions while enabling agents to discover, access and pay for resources globally.

AIsa Targets Enterprise AI Infrastructure Challenges

AIsa is addressing a challenge facing companies seeking to deploy AI agents in production: the fragmented systems used to access external data, software, models and business services.

Enterprise AI agents often need to interact with multiple providers, each with separate integrations, access requirements and billing arrangements. Managing these connections can complicate deployment and make it harder for businesses to scale agent-based workflows reliably.

The company’s infrastructure connects enterprise agents to external data sources, AI search services, models, application programming interfaces, software tools and industry-specific services. It combines governed access with usage measurement, billing and settlement.

By bringing these functions together, AIsa aims to simplify how AI agents obtain resources and account for their use. The approach also addresses the need for businesses to retain control over what agents can access, how much they can spend and which transactions they can execute.

These capabilities could become increasingly relevant as companies move beyond AI assistants that primarily generate information toward agents capable of carrying out multistep tasks involving external services.

Tether Expands Its AI and Programmable Payments Strategy

Tether Capital’s participation places the investment within the broader strategy of Tether, the issuer of the USDT stablecoin. According to the company, Tether Capital operates as an independent investment arm deploying capital from Tether’s profits and excess reserves.

In June 2024, Tether CEO Paolo Ardoino said the investment group expected to deploy at least $1 billion into deals. Its investments have extended into technology and artificial intelligence, reflecting the company’s interest in businesses beyond its core stablecoin operations.

Tether said the AIsa investment fits this broader pattern and follows its investment in NEURA Robotics. That initiative included plans to integrate Tether’s Wallet Development Kit, enabling machines to run AI locally and conduct transactions within predefined limits.

The connection between AI infrastructure and programmable payments is significant because autonomous systems may need to purchase data, access computing resources or pay for software services without requiring manual approval for every individual transaction. Such systems would still need clearly defined permissions, spending limits and safeguards.

For Tether, backing infrastructure designed around these requirements offers a way to explore potential uses of digital payments as AI agents become more capable of executing tasks independently.

AI Agents and Digital Payments Converge

The investment highlights an emerging intersection between enterprise AI, financial infrastructure and automated transactions. As AI agents gain the ability to select tools, retrieve information and execute workflows, businesses will need systems that coordinate access, usage tracking and payment across multiple providers.

AIsa’s model combines these operational requirements within a single infrastructure layer. Tether’s involvement adds a strategic investor with an established stablecoin business and an expressed interest in programmable money.

However, the funding announcement does not establish how widely AIsa’s platform has been deployed, how much transaction volume it currently processes or whether its infrastructure relies on USDT for settlement. Those details were not provided in the reported announcement.

The commercial opportunity will depend on whether enterprises adopt agent-based workflows at scale and whether infrastructure providers can meet requirements for security, governance, reliability and cost control.

Outlook

AIsa’s seed extension provides additional backing for its effort to build infrastructure connecting enterprise AI agents with external resources and payment systems. Tether Capital’s participation reinforces the growing strategic interest in enabling autonomous software to transact under defined controls. The next important indicators will be enterprise adoption, integration with payment systems and evidence that governed agent infrastructure can support reliable commercial activity at scale.
