Company Overview
OpenRouter is a New York-based AI infrastructure company that provides a unified interface for accessing and routing requests across hundreds of AI models and providers. Founded in 2023 by Alex Atallah and Louis Vichy, the company operates an AI model marketplace and gateway that allows developers and businesses to use multiple models through a single API. Its platform provides model discovery, intelligent routing, provider-level failover, cost and latency optimization, observability, and enterprise controls. OpenRouter supports more than 400 models from more than 80 providers and has expanded from developer-focused model access into infrastructure for production AI applications and agents. In May 2026, the company raised a $113 million Series B led by CapitalG. In August 2026, Stripe announced an agreement to acquire OpenRouter, with OpenRouter continuing to operate as a distinct product and brand.
QueryFeedz Insight
OpenRouter has developed a layer of infrastructure designed to address the increasing complexity of multi-model AI deployment. Instead of requiring developers to integrate separately with individual model providers, its gateway provides a common interface for accessing and routing across hundreds of models. The company's intelligent routing capabilities can consider factors such as cost, latency, provider availability, and model performance. Its May 2026 Series B brought strategic investors from across the AI and enterprise infrastructure ecosystem, while its August 2026 agreement to join Stripe represents a significant shift in ownership.
