San Francisco-based startup Kite, formerly known as Zettablock, has announced an $18 million Series A round led by Paypal Ventures and General Catalyst. With the new financing, the company’s total funding now stands at $33 million, underscoring growing investor interest in infrastructure designed for the so-called agentic web.
The round also included participation from 8VC, Samsung Next, Vertex Ventures, and Animoca Brands. The backing comes as Kite positions itself as a provider of trust infrastructure for software agents that need to identify themselves, make payments, and operate under programmable rules across digital environments.
Kite AIR Launches Alongside the Funding Round
At the same time as the funding announcement, Kite unveiled Kite AIR, a new suite built to support agent-based internet activity. According to the company, the offering includes programmable agent identities, native stablecoin payments, and policy enforcement. Named components in the suite include Agent Passport and an Agent App Store.
The launch reflects a broader industry push to create infrastructure for autonomous or semi-autonomous software agents that can interact with services, merchants, and financial systems without relying entirely on traditional user flows. In Kite’s framing, these agents require verifiable identity, access permissions, transaction capabilities, and compliance-oriented controls in order to participate in online commerce and onchain services safely.
Focus on Identity, Payments, and Governance
Kite’s product strategy centers on three core layers. The first is identity: software agents need a way to prove who they are, what system they belong to, and what permissions they hold. The second is payments: if agents are expected to buy services, complete transactions, or move funds on behalf of users or businesses, they need payment rails that are fast, low-cost, and interoperable. The third is policy: agents must be constrained by rules that define what they can access, when they can transact, and how they are allowed to operate.
By combining these functions into a unified stack, Kite is attempting to build a foundational trust layer rather than a single application. That positioning may be important as the market for agent-driven workflows expands across online retail, financial platforms, and data ecosystems.
Live Integrations With Shopify and Paypal Merchants
Kite said Kite AIR is already live and includes integrations for merchants on platforms such as Shopify and Paypal. Through these integrations, agents can authenticate, make transactions, and access services onchain. The company claims the system enables millisecond settlement and low fees, two features that are especially relevant for high-frequency or machine-driven commerce.
The mention of Shopify and Paypal is notable because it points to a practical commercial use case rather than a purely experimental blockchain deployment. Instead of focusing only on crypto-native environments, Kite appears to be targeting interfaces where merchants, payment flows, and software agents may increasingly intersect. If successful, that approach could help bridge traditional online commerce and blockchain-based transaction infrastructure.
Why Stablecoins Matter in the Agentic Web
Stablecoins are emerging as a logical payment mechanism for agent-based systems because they combine onchain settlement with price stability relative to fiat currencies. For software agents that need to pay for APIs, services, subscriptions, or goods, volatile crypto assets may introduce unnecessary risk. Stablecoins, by contrast, can support predictable transaction values while retaining the speed and programmability associated with blockchain rails.
Kite’s emphasis on native stablecoin payments suggests that the company sees digital-dollar-style assets as a key transactional layer for autonomous internet activity. In this model, agents would not only browse or retrieve data, but also pay for services and complete tasks through embedded financial logic. That could make stablecoin rails more relevant in business automation and machine-to-machine payments.
Investors Signal Confidence in Agent Infrastructure
The investor roster behind the round spans venture capital, fintech, consumer internet, and crypto-focused players. Paypal Ventures brings obvious relevance given the company’s background in digital payments, while General Catalyst adds weight from a major technology investment platform. Participation from Samsung Next, Vertex Ventures, and Animoca Brands broadens the strategic profile of the round across enterprise technology, startup ecosystems, and digital asset markets.
That combination suggests that the thesis around agentic infrastructure is no longer limited to one niche. Instead, investors appear to be evaluating the space through multiple lenses: commerce enablement, programmable finance, digital identity, and future internet architecture.
Next Steps Across Commerce, Finance, and Data
Kite said it plans to pursue further integrations across commerce, finance, and data ecosystems. While the company did not provide a detailed roadmap in the announcement, the direction indicates an ambition to expand beyond initial merchant integrations and become part of a broader operational layer for agent-based applications.
If software agents continue to gain traction in customer service, purchasing, analytics, and digital operations, infrastructure providers like Kite may play a key role in determining how these agents verify identity, move money, and comply with platform rules. In that context, the company’s latest funding round is not just about scaling a startup, but about backing a specific vision of how automated actors will transact on the internet.
For now, Kite’s announcement combines two signals the market has been watching closely: stronger venture interest in agent-focused infrastructure and a continued push to embed stablecoin-based payments into real-world digital workflows. Whether that combination translates into broad adoption will depend on execution, integrations, and merchant demand, but the company has now made its direction clear.
