The San Francisco company said the funding will expand engineering, payment infrastructure and stablecoin settlement as usage surged in the first half of 2026.
AIsa said it 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 San Francisco-based company operates what it describes as a transaction network for the AI agent economy, giving AI agents and developers a single programmable interface to discover, access and pay for AI models, APIs, real-time data, search services, SaaS tools, compute resources and agent services. It said the new capital will be used to expand its engineering team, scale payment infrastructure, add more models, data and API providers, and accelerate stablecoin settlement (payment using price-pegged digital tokens) for AI agents and businesses worldwide. AIsa said usage accelerated after its 2025 launch: from February to June 2026, registered agent users grew 150x, aggregate API calls and transactions processed through the network rose 200x, and the platform onboarded more than 50,000 registered agents without paid marketing. The company also said growth has been supported by AI agent framework ecosystems including OpenClaw and Hermes, that it ranks as the top seller and top server in the x402 ecosystem according to x402's public leaderboard, and that it integrates with emerging agent-payment initiatives from Circle, Visa and Stripe.
