Riften
Earned intelligence for every company
About
Riften builds model routing, evaluations, private models, and training environments for AI labs, AI-native companies, and enterprises.
We help teams choose models for their workloads, evaluate how they perform, and build private models around company-specific work. We’re also developing coding environments where agents learn through backend engineering tasks.
