Ramp built a tool to cut its own runaway AI bill. Now it's giving that tool away, for free, to every business that wants one.
Ramp launched Router.com on August 19, a single API that lets companies switch between AI models from OpenAI, Anthropic, xAI, Nvidia, DeepSeek, Moonshot and Z.ai without rewriting their code. It's free to use through the end of 2026. Businesses still pay the underlying model providers for inference. New signups get a $26 launch credit.
The pitch rests on one number. Ramp says customers already routing traffic through it have cut their inference costs by roughly 40 percent on average. That's not a marketing estimate pulled from a lab test. Ramp built this system to manage its own AI spend over the past three years, before deciding the tool it built for itself was worth handing to everyone else.
Router sits between a company's application and every model provider it connects to. A developer wires up once, and Router decides, request by request, which model handles the job based on cost, speed or accuracy. Ramp also runs its own internal benchmark, called Ramp SWE-Bench, testing new models against real engineering work pulled from Ramp's own codebase. When a cheaper or better model clears that bar, Router quietly updates its defaults. No rebuild required. The service is US-only for now, and according to TechCrunch's reporting on the launch, Router keeps inputs, outputs and tool calls on file for a year by default, under an opt-out data policy.
Ramp's free launch landed two days after Stripe closed a deal worth more than $7 billion to acquire OpenRouter, a deal Forbes and several other outlets confirmed this week. OpenRouter already routes traffic for roughly 8 million developers across more than 400 models. Stripe now owns both the routing layer and, as the payments processor underneath it, the billing relationship with the model providers on the other end.
Stripe Agrees to Buy AI Router OpenRouter for More Than $7 Billion Stripe has reportedly agreed to buy OpenRouter, the startup whose API routes developer requests across more than 400 AI models, for more than $7 billion, according to Bloomberg. That's over five times OpenRouter's $1.3 billion valuation from a funding round closed just months earlier, and the deal hands one of the world's largest payment... - stripe acquires openrouter ai router company for billions - openrouter seven billion dollar acquisition by stripe announced
That scale cuts both ways. A CNBC investigation published July 7 found that Chinese-origin models had grown to capture 46 percent of US enterprise token usage on OpenRouter. American models, meanwhile, slid from around 70 percent of the platform's token volume in mid-2025 to roughly 30 percent a year later, as cheap, open-weight Chinese models absorbed the difference. Stripe now sits in the middle of that shift, billing for the same Chinese labs whose traffic its own router increasingly favors.
Ramp is making a narrower, cheaper bet than Stripe. It didn't buy a marketplace with 8 million developers on it. It built a router to solve its own cost problem, and it's giving that router away to sell its actual business: corporate cards, expense software and bill pay. Frankly, the incentives line up neatly. Stripe just spent $7 billion on a product that increasingly directs enterprise traffic to Chinese labs it also profits from billing. Ramp gives its router away because a lower AI bill for its customers is a lower AI bill running through Ramp's own payment rails.
Enterprise AI spending keeps climbing. That's true no matter which router wins. DeepSeek and Moonshot's Kimi models have forced OpenAI and Anthropic to compete on price as well as capability this year, and that price war is exactly what Ramp is selling into. A finance company that already tracks what businesses spend on everything else now wants to be the company deciding what they spend on AI models too. Whether that position is worth more than a free router, nobody, including Ramp, has said yet.
