As AI agents begin to autonomously execute tasks, they need a new infrastructure for payments and resource discovery. AIsa aims to become the 'transaction layer' in this domain, backed by Alibaba and Tribe Capital.
As AI agents shift from answering questions to executing actions on behalf of users, they need access to models, APIs, data, software tools, and digital services. However, existing digital resources are designed for humans, involving account creation, API key management, subscription plans, and manual payment processes that autonomous agents cannot handle efficiently. AIsa aims to resolve this fundamental contradiction.
AIsa provides a unified transaction layer that allows AI agents and developers to discover, access, and pay for digital resources through a single programmable interface. The platform integrates two historically separate components: a resource gateway connecting agents to needed digital resources, and an agent payment layer that meters usage, enforces business-defined spending controls, and settles transactions. Available resources include AI models, APIs, real-time data, search services, SaaS tools, compute resources, and agent services, with usage-based billing and settlement in fiat or stablecoins.
AIsa launched in 2025 and saw usage accelerate sharply in the first half of 2026. From February to June 2026, registered agent users grew 150x, and transaction volume from aggregated API calls and network processing grew 200x. The company has onboarded over 50,000 registered agents without paid marketing. Growth has coincided with the rise of next-generation AI agent framework ecosystems like OpenClaw and Hermes, which bring a highly AI-native developer base.
According to x402's public leaderboard, AIsa ranks as a top seller and top server in the x402 ecosystem. It also integrates with emerging agent payment initiatives from Circle, Visa, and Stripe. These integrations suggest AIsa is positioning itself as a candidate for the core network layer in the agent economy.
Alibaba Investment Director Qin Jin stated that AI agents will require a new transaction and commerce layer to interact with digital resources globally, and AIsa has demonstrated strong execution. Tribe Capital investor Francis Zhan noted that existing monetization rails (advertising, subscriptions, manual onboarding, enterprise sales) do not map cleanly to agents, and AIsa sits at the intersection of AI, payments, and marketplace infrastructure, with early traction positioning it favorably in agent-resource transactions.
The new funds will be used to expand the engineering team, extend payment infrastructure, onboard more model, data, and API providers, and accelerate stablecoin settlement capabilities for global AI agents and enterprises. AIsa also plans to expand its resource marketplace, deepen enterprise control features (including budgets, approval workflows, and audit trails), and extend the infrastructure needed for autonomous agents to transact securely at scale.
This article's information primarily comes from AIsa's official press release and investor statements, which are first-hand sources. Growth data (150x, 200x, 50,000 agents) is self-reported by the company and has not been independently verified by third parties. The x402 leaderboard ranking and integrations with Circle/Visa/Stripe are claimed by the company, with the depth of integration not disclosed.
AIsa is building a transaction network for AI agents akin to 'PayPal for agents.' Its early growth and backing from top-tier investors indicate real demand in this direction, but as an emerging infrastructure, its long-term value depends on whether it can become the standard transaction layer for the agent economy.
