NVentures, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures, Databricks Ventures join CapitalG, a16z, Menlo Ventures, and others in backing the high-growth AI infrastructure startup

NEW YORK: OpenRouter, the AI model exchange, today announced a $113 million Series B led by Alphabet’s independent growth fund, CapitalG, with participation from investors including NVentures (NVIDIA’s venture capital arm), ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures, Databricks Ventures, alongside existing investors including Andreessen Horowitz and Menlo Ventures.

OpenRouter’s volume has surged to 25 trillion tokens per week (100 trillion tokens per month), representing a 5X increase from the 5 trillion tokens processed per week just six months ago. The explosion in token demand illustrates how quickly enterprises are deploying agents and scaling AI across multiple models and providers. OpenRouter’s infrastructure manages and optimizes inference and provides access to 400+ models across leading AI providers, including Anthropic, Google, OpenAI, xAI, and DeepSeek, among others. The platform is used by over 8 million global users, including AI-native startups and large enterprises, and its rankings and usage data have become a widely referenced signal of real-world model adoption, performance, and pricing dynamics.

The company will use the new capital to expand its routing, governance, and optimization capabilities as enterprises increasingly deploy AI into production. A 2026 Deloitte study found that 67% of enterprises are already consuming over one billion tokens per month. OpenRouter is seeing a shift toward multi-model strategies, where companies route across models and providers to optimize for cost, latency, and capability, creating operational complexity that requires centralized control.

"Running inference at scale is fundamentally a multi-model problem. The era of picking a single model is over," said Alex Atallah, CEO and co-founder of OpenRouter. "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."

“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,” said Mo Jomaa, partner at CapitalG.

“As companies shift toward a multi-model paradigm, OpenRouter enables them to seamlessly leverage the right model for every task,” added Jane Alexander, partner at CapitalG. “OpenRouter is uniquely positioned to become the data clearinghouse and unified intelligence layer for AI models.”

As AI usage has exploded worldwide, OpenRouter’s public rankings and usage data have become a widely referenced source of real-world insight into model adoption, performance, and pricing, used by investors, researchers, and media organizations to understand how the AI market is evolving.
