AIsa, a San Francisco–based company building what it describes as the transaction network for the AI agent economy, has raised $6.5 million in total funding to date, including a new seed round co-led by Alibaba and Tribe Capital, with participation from Draper Associates, Sumitomo Corporation, Saison Capital and other investors. The capital will be used to expand AIsa’s engineering team, scale its payment infrastructure, onboard additional models, data, and API providers, and accelerate stablecoin settlement capabilities for AI agents and businesses worldwide.
The company’s core thesis is that AI agents are transitioning from answering questions to taking actions on behalf of users—researching, calling tools, consuming data, and making payments autonomously. But most digital resources are still designed for human users, requiring account creation, API key management, subscription plans, and manual payment workflows that autonomous agents cannot efficiently navigate. AIsa provides a unified transaction layer that lets AI agents and developers discover, access, and pay for digital resources through a single programmable interface, with usage-based billing and settlement in fiat or stablecoins.
The platform combines two functions that have historically been separate: a resource gateway that connects agents to the models, APIs, real-time data, search services, SaaS tools, compute resources, and agent services they need; and an agentic payment layer that meters usage, enforces business-defined spending controls, and settles transactions. Customers such as Impossible Finance use AIsa to access AI models, data, and APIs through a single interface, paying only for actual usage rather than managing multiple vendor contracts and subscriptions. Enterprise controls, including budgets, approval workflows, and audit trails, are part of the roadmap as AISA moves toward supporting autonomous agents transacting securely at internet scale.
Since launching in 2025, AIsa has seen sharp acceleration in the first half of 2026. From February to June 2026, registered agent users on the platform grew 150-fold, while aggregate API calls and transactions processed through the network grew 200-fold. The company has onboarded more than 50,000 registered agents without paid marketing. Growth has been driven in part by the rise of next-generation AI agent framework ecosystems, including OpenClaw and Hermes, which have brought a highly AI-native developer base into AIsa’s network. According to x402’s public leaderboard, AIsa ranks as the top seller and top server in the x402 ecosystem, and it integrates with emerging agent-payment initiatives from Circle, Visa and Stripe.
Investors frame the opportunity as analogous to prior platform transitions in payments. Alibaba’s investment director Qin Jin describes AIsa as building critical infrastructure that makes AI resources more accessible across international markets, seeing it as a foundational layer for a new transaction and commerce category. Tribe Capital’s Francis Zhan draws a direct parallel to prior monetization revolutions—arguing that existing rails such as ads, subscriptions, manual onboarding and enterprise sales do not map cleanly to autonomous agents, and that AIsa sits at the intersection of AI, payments and marketplace infrastructure with early traction that positions it as a core network layer for the agent economy.
KEY QUOTES:
“Every major payment network won by sitting next to the resources its users actually wanted to buy. PayPal grew alongside eBay, and Stripe grew alongside internet commerce. AI agents are becoming economic actors. They research, call tools, consume data and make payments on behalf of users and businesses. But they cannot operate through signup flows, subscriptions and checkout pages designed for humans. AIsa is building the marketplace where agents get the resources they need and the transaction rail they pay with.”
Jordan Liu, Founder and CEO, AIsa
“We believe AI agents will require a new transaction and commerce layer to interact with digital resources at global scale. AIsa has shown strong execution in this emerging category and is building critical infrastructure that makes AI resources more accessible across international markets.”
Qin Jin, Investment Director, Alibaba Group
“As agents become first class citizens of the internet, we believe they will need to pay for APIs, data, compute, identity, permissions, and services in a more programmatic way than humans do. Existing monetization rails like ads, subscriptions, manual onboarding, enterprise sales do not map cleanly to agents. AIsa sits at the intersection of AI, payments and marketplace infrastructure, and its early traction in agent-to-resource transactions gives it a strong position to become a core network layer for the agent economy.”
