OpenRouter secures $113 million Series B led by CapitalG as AI usage surges
The routing layer provider, backed by strategic investors including NVentures and ServiceNow Ventures, aims to process a quadrillion tokens this year as the sector shifts from experimentation to production.
OpenRouter has secured a $113 million Series B funding round led by CapitalG, the independent growth fund of Alphabet. The investment round includes participation from a cohort of strategic investors comprising NVentures, the venture capital arm of NVIDIA, alongside ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures, Databricks Ventures, AMP PBC, and Pace Capital. Existing backers Andreessen Horowitz and Menlo Ventures also participated in the round.
The company reported significant traction in its core metrics, with weekly volume on the platform growing from 5 trillion to 25 trillion tokens over the past six months. OpenRouter currently serves more than 8 million developers building applications across more than 400 models. Based on current growth trajectories, the company stated it is on pace to process over a quadrillion tokens this year.
OpenRouter operates as a routing and gateway layer positioned between AI agents and model providers. Its infrastructure handles critical production functions including routing, reliability, cost optimisation, and compliance. The company describes its role as essential for managing the complexity of multi-model systems, allowing organisations to navigate different providers, modalities, and use cases without building custom integrations for each.
The composition of the investor group reflects a broader shift in the artificial intelligence sector from experimentation to critical production applications. CapitalG, NVentures, and the venture arms of ServiceNow, MongoDB, Snowflake, and Databricks represent platform companies that enterprises already rely upon. Their participation signals a market consensus on the necessity of a dedicated routing layer as organisations move beyond single-model pilots to complex, multi-model production systems.
OpenRouter intends to utilise the fresh capital to scale its infrastructure, deepen enterprise capabilities, and invest further in intelligent routing technologies. The company emphasised that production AI requires infrastructure capable of working reliably at scale, and the funding will support efforts to help teams identify the optimal model and provider for every request. The valuation of the company post-funding was not disclosed in the announcement.
