OpenRouter more than doubles valuation to $1.3B in a year - TechCrunch

OpenRouter, a company that provides a unified API for accessing multiple large language models, has raised $113 million in Series B funding led by CapitalG. The round values the company at $1.3 billion, more than double its valuation from a year ago. OpenRouter's service allows developers to compare and switch between different LLMs without managing separate API integrations.

OpenRouter's model is designed to simplify access as the number of available LLMs grows.

The significant valuation increase reflects investor confidence in the API aggregation layer within the AI infrastructure stack. The company faces competition from model providers offering direct access and from other aggregators.
