OpenRouter raises $113M

Why it matters

OpenRouter said on May 26 that it raised $113 million in a Series B round led by CapitalG, Alphabet’s independent growth fund, to expand software that routes customer requests across different artificial-intelligence models. The company said the round also included NVentures, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures, Databricks Ventures, Andreessen Horowitz and Menlo Ventures. OpenRouter described itself as an “AI model exchange” that gives developers and companies access to more than 400 models through one API. The company said the new money will fund more routing, governance and optimization tools for enterprise customers. ### What exactly does OpenRouter sell? OpenRouter said it manages inference traffic and gives customers access to models from providers including Anthropic, Google, OpenAI, xAI and DeepSeek. The company said its platform is used by more than 8 million global users and has become a reference point for model usage, pricing and performance data. OpenRouter’s pitch is that customers do not need to commit to one model provider and can switch requests based on cost, latency and capability. (secure.businesswire.com) Alex Atallah, OpenRouter’s chief executive and co-founder, said in the funding announcement that “running inference at scale is fundamentally a multi-model problem” and that “the era of picking a single model is over.” Atallah previously co-founded OpenSea, and OpenRouter says it started in early 2023.

CapitalG partner Mo Jomaa said OpenRouter is addressing “the infrastructure gap for inference in the AI era,” comparing the company’s position to earlier infrastructure businesses such as Cloudflare, Stripe and Databricks. Jane Alexander, also a partner at CapitalG, said companies adopting a multi-model approach need a way to use “the right model for every task.” Those statements frame the investment around software that sits between model makers and enterprise buyers, rather than around building a single frontier model. (secure.businesswire.com) Trending Topics reported the round valued OpenRouter at about $1.3 billion. The same report said that was more than double the value of the company’s previous round. OpenRouter did not state a valuation in its own announcement. ### Which numbers in the round are drawing attention? OpenRouter said weekly volume reached 25 trillion tokens, equal to 100 trillion tokens a month, up from 5 trillion tokens a week six months earlier. (secure.businesswire.com) The company said that increase reflects broader enterprise use of AI agents and applications spread across multiple providers. (trendingtopics.eu) A 2026 Deloitte study cited by OpenRouter found that 67% of enterprises are already consuming more than 1 billion tokens a month. OpenRouter used that figure to argue that companies are moving toward multi-model deployments that create more operational complexity around cost control, reliability and governance. (secure.businesswire.com) ### How does OpenRouter say customers use the platform? Trending Topics reported that OpenRouter offers a unified API for more than 400 models and routes requests automatically based on latency, cost and quality. The publication said the company’s “Auto Exacto” feature directs traffic to what it identifies as the most efficient provider for a given request. It also reported that open-source models from DeepSeek and Tencent recently ranked highly on platform usage statistics. (secure.businesswire.com) OpenRouter said its next step is to expand routing, governance and optimization capabilities as more enterprises move AI systems into production. The company’s May 26 announcement named CapitalG, NVentures, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures and Databricks Ventures among the participants backing that buildout.
