What they do

Problem

Engineering teams struggle to ship AI to production because the required tooling is fragmented across many vendors, making systems brittle and expensive without a dedicated ML platform team.

Solution

A unified multimodal inference platform and proprietary inference engine (Ion) that provides routing, semantic caching, continuous evaluation, simulated data, and one-click fine-tuning on a custom GPU fleet.

Who it's for

Software engineering teams building AI products at companies that want to run production AI without a dedicated ML platform team.
