AI agents are already being used to book meetings, manage workflows, and run code. The next step is letting them pay for things, and that requires a purpose-built layer that existing payment systems were never designed for. SolvaPay is building exactly that: payment infrastructure for the agentic economy, where AI agents can find, negotiate, and pay for digital services on behalf of users and businesses.
The Stockholm-based startup has announced €2.4 million in pre-seed funding to build out its payment infrastructure platform. This is SolvaPay’s first institutional round, and the timing lines up with a broader industry shift toward agent-driven commerce becoming a practical reality rather than a theoretical concept.
The Funding Breakdown:
The round was led by European FinTech venture capital firm Redstone and Silicon Valley-based MS&AD Ventures, with additional participation from Antler and Greens Ventures. Both Antler and Greens Ventures are also investors in Lovable, which gives the cap table a clear thread of conviction in European developer infrastructure plays.
The newly secured funding will be used to accelerate the development of SolvaPay’s machine-native payment rails and agentic revenue infrastructure, expand the engineering team, and support early adoption among businesses seeking to participate in the emerging agentic economy.
The Problem SolvaPay Solves:
Most payment infrastructure today works fine for humans checking out on a website or subscribing to a SaaS tool. It breaks down the moment an AI agent tries to do the same thing autonomously. Current digital services enable seamless transactions, but only within closed ecosystems, which prevents AI agents from freely interacting, negotiating, and transacting across platforms.
This is a structural gap. An AI agent running inside Claude or ChatGPT might identify a data service it needs, but it has no native way to authenticate, subscribe, and pay for that service in a single flow. SolvaPay is building the layer that makes that flow possible.
How the Product Works:
SolvaPay’s system is built for SaaS providers, API businesses, and developer tools that want a single integration to make their products discoverable and purchasable across AI ecosystems such as Claude and ChatGPT. Businesses connect their MCP server or API to SolvaPay, and the platform handles authentication, checkout, and billing from there.
The product supports subscriptions, usage-based billing, one-time purchases, and hybrid pricing models. Developers can also set up agent credits, where a balance is pre-loaded and agents draw down in real time against a defined spending limit. Revenue runs through the business’s own Stripe account, so there is no revenue share or middleman between the business and its customers.
The Team:
SolvaPay’s founding team brings more than five decades of combined experience across financial services and technology companies, including Spotify, FIS, Bank of America, Lehman Brothers, and Handelsbanken. That depth matters here because building payment rails means navigating compliance, financial regulation, and infrastructure in ways that pure software startups often underestimate.
CEO and co-founder Viggo Stenseth has been direct about the company’s positioning: “Every major technological shift has needed a financial layer before it could become a real economy. The internet needed it. E-commerce needed it. Now, we’ve reached the same point with the agentic economy.”
What Businesses Can do With it:
For developers building on top of AI platforms, the SolvaPay integration is straightforward. Running npx solvapay init wraps any endpoint with payment logic. From there, businesses can set tool-level pricing, meaning individual API tools within a product can be priced independently, some free, some paid, some usage-capped.
SaaS providers, API businesses, and developer tools can use a single integration with SolvaPay to make their products discoverable and purchasable on platforms like Claude, ChatGPT, and other AI ecosystems, which opens up a new customer base: AI agents. For companies that already sell to developers, this is a meaningful expansion of who, or what, can become a buyer.
The platform also supports the x402 machine-to-machine payment standard over regular financial rails, without requiring any cryptocurrency. SOC2, CISO, and ISO27001 certifications are currently in progress, which is the expected compliance trajectory for a company at this stage.
The Bigger Picture:
Agent-driven commerce is projected to reach $3 to 5 trillion by 2030. Building the payment infrastructure that connects AI agents to billable digital services early gives SolvaPay a strong positioning in what is shaping up to be a core category of FinTech infrastructure.
SolvaPay is free to start, with a 1% fee plus Stripe processing costs applied only when a transaction completes. For founders and developers looking to make their products accessible to AI agents, that entry point keeps the barrier low while the platform scales with usage.
If you are curious about how other FinTech infrastructure startups are approaching developer-first monetization, the broader European FinTech funding landscape in 2026 offers useful context for where investor conviction is currently sitting.
