Kite, a company building the foundational trust infrastructure for the agentic web, announced that it has raised $18 million in Series A funding, bringing total cumulative funding to $33 million. The round was led by PayPal Ventures and General Catalyst. Formerly known as Zettablock, Kite leverages years of experience in distributed infrastructure systems to bring forth a new architecture purpose-built for the agentic web. The company recently launched Kite Agent Identity Resolution, or “Kite AIR” – a pioneering solution that enables autonomous agents to authenticate, transact, and operate independently in real-world environments. The system delivers programmable identity, native stablecoin payment, and policy enforcement on a blockchain optimized for autonomous agents. Kite AIR includes two core components: Agent Passport, a verifiable identity with operational guardrails; and Agent App Store, where agents can discover and pay to access services such as APIs, data, and commerce tools. It is live now through open integrations with popular commerce platforms like Shopify and PayPal. Using publicly available APIs, any PayPal or Shopify merchant can opt in through the Kite Agent App Store and become discoverable to AI shopping agents. Purchases are settled on-chain with full traceability, using stablecoins and programmable permissions. Kite is also actively building additional integrations across commerce, finance, and data platforms. “Solutions like virtual cards provide only short-term workarounds. Latency, fees, and chargebacks further complicate things. Kite bridges this critical gap by providing stablecoin-based, millisecond-level settlement with low transaction fees and no chargeback fraud risks. This enables new economic models such as agent-to-agent metered billing, micro-subscription, and high frequency trading,” said Alan Du, Partner at PayPal Ventures.
