OpenRouter Raises $113M Series B

OpenRouter · 5/28/2026

Today we’re announcing our $113M Series B, led by CapitalG (Alphabet’s independent growth fund), with participation from NVentures (NVIDIA’s venture capital arm), ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures, Databricks Ventures, AMP PBC, and Pace Capital, alongside our existing investors Andreessen Horowitz and Menlo Ventures.

今天，我们宣布完成 1.13 亿美元的 B 轮融资。本轮融资由 CapitalG（Alphabet 旗下的独立成长基金）领投，NVentures（NVIDIA 的风险投资部门）、ServiceNow Ventures、MongoDB Ventures、Snowflake Ventures、Databricks Ventures、AMP PBC 和 Pace Capital 跟投，现有投资者 Andreessen Horowitz 和 Menlo Ventures 也参与了本轮投资。

Where we are

Over the last six months, weekly volume on OpenRouter has grown from 5 trillion to 25 trillion tokens. We are on pace to process over a quadrillion tokens this year and serve 8M+ developers building across 400+ models. AI is rapidly shifting from experimentation into critical production apps and agents, and that transition requires infrastructure that works reliably at scale, across providers, across modalities, and across use cases. This growth reflects the simple fact that developers love building on OpenRouter.

我们所处的阶段

在过去六个月里，OpenRouter 的周处理量已从 5 万亿 token 增长至 25 万亿 token。我们预计今年将处理超过 1 千万亿 token，并为 800 多万名开发者提供服务，支持他们在 400 多种模型上进行构建。人工智能正迅速从实验阶段转向关键的生产级应用和智能体，这一转型需要能够在不同提供商、不同模态和不同用例之间可靠运行的大规模基础设施。这种增长反映了一个简单的事实：开发者热衷于在 OpenRouter 上进行开发。

Why this round matters

The composition of this investor group is deliberate. CapitalG, NVentures, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures, and Databricks Ventures are more than financial backers; they are the infrastructure and platform companies that enterprises already depend on. Their participation reflects a shared view: as organizations move from single-model pilots to multi-model production systems, they need a routing and gateway layer purpose-built for that complexity. OpenRouter is that layer. We sit between agents and model providers, handling the routing, reliability, cost optimization, and compliance that production AI demands. The breadth of strategic investors in this round signals that the market has converged on this as a critical piece of the stack.

本轮融资的意义

本轮投资者组合是经过深思熟虑的。CapitalG、NVentures、ServiceNow Ventures、MongoDB Ventures、Snowflake Ventures 和 Databricks Ventures 不仅仅是财务支持者，它们更是企业已经深度依赖的基础设施和平台公司。它们的参与反映了一个共识：随着组织从单一模型的试点转向多模型的生产系统，他们需要一个专为应对这种复杂性而构建的路由和网关层。OpenRouter 正是这一层。我们位于智能体和模型提供商之间，处理生产级 AI 所需的路由、可靠性、成本优化和合规性。本轮战略投资者的广泛参与表明，市场已达成共识，将其视为技术栈中至关重要的一环。

What we’ve been building

The past year has been focused on expanding what OpenRouter can do for production workloads:

• Multimodal inference: Beyond text, OpenRouter now supports image, audio, speech, transcription, embedding, and video models.
• Enterprise controls: Workspaces, spend management, guardrails, and zero-data-retention policies for organizations deploying AI at scale.
• Intelligent routing: Provider-level failover, cost and latency optimization, and quality-aware routing that goes beyond simple load balancing.

我们一直在构建的内容

过去一年，我们专注于扩展 OpenRouter 在生产工作负载方面的能力：

• 多模态推理： 除了文本，OpenRouter 现在还支持图像、音频、语音、转录、嵌入（embedding）和视频模型。
• 企业级控制： 为大规模部署 AI 的组织提供工作空间（Workspaces）、支出管理、护栏（guardrails）和零数据保留策略。
• 智能路由： 提供商级别的故障转移、成本与延迟优化，以及超越简单负载均衡的质量感知路由。

What’s next

We’ll use this funding to continue scaling our infrastructure, deepen enterprise capabilities, and continue to invest in intelligent routing; teams need help finding the right model and provider for every request. We’re grateful to our customers, partners, investors, and the developer community building with us as we continue scaling the infrastructure layer for the multi-model AI era.

未来展望

我们将利用这笔资金继续扩展基础设施，深化企业级功能，并持续投入智能路由研发；团队需要帮助，以便为每一次请求找到最合适的模型和提供商。我们衷心感谢客户、合作伙伴、投资者以及与我们共同构建的开发者社区，我们将继续为多模型 AI 时代扩展基础设施层。
