OpenRouter announced it has raised $113 million in Series B funding, led by CapitalG, with participation from NVentures, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures, Databricks Ventures, and existing investors Andreessen Horowitz and Menlo Ventures.
The company said its platform volume has surged to 25 trillion tokens processed per week, or about 100 trillion tokens per month, representing a fivefold increase from six months ago when it was processing 5 trillion tokens weekly. OpenRouter attributed the rapid growth to increasing enterprise adoption of AI agents and multi-model AI deployments.
Founded in 2023, OpenRouter operates an AI model exchange platform that enables developers and enterprises to access and route requests across more than 400 AI models through a single API. The platform integrates with providers including Anthropic, Google, OpenAI, xAI, and DeepSeek.
The company said its infrastructure is used by more than 8 million users globally, ranging from AI-native startups to large enterprises. OpenRouter added that its public rankings and usage data have become widely referenced indicators for tracking model adoption, pricing trends, and performance across the AI industry.
According to the company, the newly raised capital will be used to expand its routing, governance, and optimization capabilities as enterprises increasingly deploy AI systems into production environments. OpenRouter cited a 2026 Deloitte study showing that 67% of enterprises are already consuming more than one billion AI tokens per month.
The company said enterprises are increasingly adopting multi-model strategies that route requests across various AI providers in order to optimize cost, latency, reliability, and performance. OpenRouter believes this shift is creating operational complexity that requires centralized infrastructure and orchestration layers.
Alex Atallah, CEO and co-founder of OpenRouter, said the AI market is moving beyond reliance on a single foundational model provider.
KEY QUOTES:
“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.”
Alex Atallah, CEO and Co-Founder, OpenRouter
“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.”
Mo Jomaa, Partner, CapitalG
“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.”
