Today, we are excited to announce that we are joining forces with Stripe, to power the next wave of GDP growth globally.

OpenRouter is the first and largest model marketplace and gateway. We are the best way to discover and use any AI model, with one interface, broad provider choice, model-agnostic observability, cost management, and routing that improves price, performance, and uptime. We now process 10+ trillion tokens per day from 400+ AI models for a community of over 10 million developers and companies. Since our founding, we have seen at least 10x growth in inference volume every year.

We want to explain why we made the decision to join forces with Stripe and what it means for the millions of developers and companies that build on us.

What this means for our users

OpenRouter will continue to operate as it is: same mission, same name, same product, same roadmap. If you build on OpenRouter today, nothing about your integration changes.

OpenRouter exists to give users every model on equal footing, provide open signals about how they’re used in the market, help developers orchestrate them together, and make them observable and manageable at scale. That commitment is core to how we operate, and it doesn’t bend to any model, any provider, or any parent company. It also extends to a growing ecosystem of inference-adjacent services, including AI-native web search, context management, and more to come.

Routing decisions will remain driven by one thing: what’s best for you, the user.

Our mission

We started OpenRouter in early 2023 on a simple belief: intelligence will be multi-model. No single model will win every task, and the frontier will move rapidly. That freedom is critical infrastructure for the industry. AI is too important for its future to be decided by whichever single model gets embedded first. AI has become the single largest driver of economic growth in the US, and inference is quickly becoming the largest line item for every company.

We envision a healthy AI ecosystem where many models thrive, where AI neurodiversity is a strength, where a lab or an inference provider with a breakthrough can reach millions of developers, and where no single model becomes the default by inertia.

Our mission is to realize this future, and it’s more important than anything else. The opportunity with Stripe allows us to accelerate it together.

Why Stripe?

There are few companies on earth we would have considered selling to; our mission, our neutrality, and our lead in the market make the story for independence strong. We would only join a company if we thought we could do more together, faster, without compromising any of them.

Stripe is that company. They are the best financial infrastructure platform in the world. Their API set the standard that developer products, including ours, have been measured against ever since. This is a combination of two platforms that developers choose on merit, with cultures focused on quality, scale, and commitment to builders, and that will remain essential in a post-AGI economy.

For years, OpenRouter has been called “Stripe for LLMs.” Both companies share common DNA: we abstract complex infrastructure and market dynamics into delightful APIs, and we obsess over the developer and user on the other side of it. Businesses trust Stripe to optimize every part of their revenue stack, across payment methods, authorization, fraud, and more. Builders, customers, model labs, and providers trust OpenRouter to run a neutral, reliable layer across a fast-moving ecosystem.

Stripe brings a large customer network, data on how internet businesses grow, and years of experience running trusted global infrastructure. There is also no one better at managing fraud and abuse, something we believe will only become more challenging for AI companies to address. We can now serve developers at a pace we couldn’t reach alone.

What’s next

To our customers: Thank you. We’re honored to be part of your journey, and we’re just getting started. OpenRouter’s product, mission, and current commitments remain unchanged. Joining Stripe helps us pursue them faster, and our ability to support you will only improve.

To our employees: We firmly believe that the next few years will be the most important time of our lives, and the most important for our mission. We are so grateful to have the privilege of being alive during this transformation for the world, and that I get to do it with you. You are some of the most brilliant, creative, curious, and determined people there are, and we’re excited to grow our team for an even greater global impact.

To everyone else who believes in our mission: come join us. Fitting into a role isn’t as important as having our values: curiosity, rigor, agency, and transparency. AI will transform the way companies are organized, and OpenRouter will innovate significantly here. And as we grow, we will relentlessly aim to preserve the velocity, agility, efficiency, and talent density of the 90-person startup that we are today.
