About RouterPlus
Summary
RouterPlus runs a marketplace that routes AI inference workloads to the right model at the lowest provider price. It tests candidate models against a team's actual traffic, lets providers bid for the workload, and keeps a backup provider live for failover. Teams call everything through a single API, replacing the default practice of sending every task to the most expensive model regardless of whether a cheaper one would do the job.
Business model
A fee on each inference request routed through the platform.
Go-to-market
B2B teams running AI in production, reached through direct sales and a single API integration that replaces existing inference calls with no model-selection work on the customer's side.

Marketplace for AI inference: the right model at the best price
RouterPlus is a marketplace for AI inference. We find the right AI model for a team's product, then get it served at the team's scale, at the best price. Most teams that run AI in production pay for a top model on every task, when a cheaper model can do most of the work. The same model can also cost twice as much depending on which provider runs it, and many providers fail at peak traffic. RouterPlus tests models on a team's own traffic and recommends one. Providers then compete for the workload. We check that the chosen provider can hold the team's real peak, and we keep a second provider ready as a backup. Teams call the model through one API. Our largest customer runs 3 million agent conversations a day on RouterPlus.
