Multi-LLM API Router & Cost Optimizer

A middleware service that automatically routes requests across multiple LLM providers (Claude, ChatGPT, Gemini, DeepSeek, etc.) to minimize costs and maximize availability. Developers get one API key and let the system optimize behind the scenes.

LLM API spend is a real pain point right now as teams run multi-model experiments and production costs compound — DeepSeek's emergence alone has reshuffled pricing assumptions and created genuine arbitrage opportunities across providers. PortKey and OpenRouter already occupy this space directly, with OpenRouter in particular having meaningful developer adoption, so the competitive hurdle is real and not just theoretical. The $3k–15k/mo revenue band is plausible but tight: margin depends entirely on whether you charge a markup on pass-through tokens or a flat subscription, and developers are notoriously resistant to paying for infrastructure abstraction they think they can build in a weekend. The most likely failure mode is exactly that — low perceived switching cost means a single motivated engineer at a target customer just rolls their own router rather than paying for yours.
