OpenRouter, a platform that gives developers and enterprises access to more than 400 AI models through a single API, has raised $113 million in a Series B round led by CapitalG, Alphabet's independent growth equity fund. The round included NVentures, NVIDIA's venture capital arm, corporate venture funds from ServiceNow, MongoDB, Snowflake and Databricks, and venture capital firms Andreessen Horowitz and Menlo Ventures.
The company says it now handles 25 trillion tokens per week, equivalent to roughly 100 trillion tokens per month, a fivefold increase from six months ago. That volume reflects a structural change in how enterprises consume AI: rather than committing to a single foundation model provider, companies are distributing workloads across OpenAI, Anthropic, Google, xAI, DeepSeek and other providers based on price, speed, reliability and task performance.
OpenRouter sits between those providers and the applications that call them. Its system routes requests, manages failover if a provider becomes unavailable, tracks usage across accounts and is designed to limit vendor lock-in for companies building AI into production systems. The platform reports more than 8 million users globally, spanning AI-native startups and large enterprises.
The funding arrives as enterprise token consumption has reached a scale that was difficult to anticipate even two years ago. A 2026 Deloitte study cited by the company found that 67 percent of enterprises already consume more than 1 billion tokens per month. As AI agents spread into customer support, software development, research and internal operations, inference traffic has become one of the fastest-growing cost items in enterprise computing.
Alex Atallah, CEO and co-founder of OpenRouter, described the core problem his company is built to address: "Running inference at scale is fundamentally a multi-model problem. The era of picking a single model is over. Success now depends on continuously routing across a changing market. Because OpenRouter sits in the flow of production traffic, we can optimize every request for cost, performance, and reliability in real time."
Mo Jomaa, a partner at CapitalG, framed the investment around a pattern he sees repeating across major technology transitions: "Every platform shift creates infrastructure gaps: from Cloudflare with the internet and Stripe with digital payments, to Databricks with data and AI. These infrastructure gaps create opportunities for generational businesses to solve real customer needs. OpenRouter is solving the infrastructure gap for inference in the AI era."
CapitalG partner Jane Alexander described OpenRouter's potential role in the AI stack: "As companies shift toward a multi-model paradigm, OpenRouter enables them to seamlessly leverage the right model for every task. OpenRouter is uniquely positioned to become the data clearinghouse and unified intelligence layer for AI models."
The Series B follows a $40 million Seed and Series A round closed a year earlier, led by Andreessen Horowitz and Menlo Ventures, with additional participation from Sequoia and angel investors. Founded in 2023, OpenRouter plans to use the new capital to expand its routing, governance and optimization systems as enterprise AI deployments grow more complex to manage.
The company's traffic and adoption data have become a reference point for investors, researchers and developers tracking which AI models are gaining commercial traction and where enterprise demand is shifting between providers.
