What Riften does
Intelligence will be the most valuable asset a company owns. Today, almost every company rents it. Companies pay a handful of labs one token at a time. Each dollar buys an answer, not an asset. They spend more, but own nothing more. Riften reverses that. Change one environment variable and Riften becomes the gateway for a company's AI traffic. We route each request to the lowest-cost model that can do the job, serving most work on open-weight models we host. Customers save money immediately without rebuilding their products. The gateway is the entry point. Over time, Riften turns the company's work into private models built on open weights and shaped around the business. What begins as cheaper inference becomes an intelligence stack the company owns, runs on infrastructure it controls, and uses to power its most important applications. We call this earned intelligence. It is created by the company's own work, controlled by the company, and accumulated over time. The next generation of companies will not rent their intelligence. They will earn it, own it, and compound it. Riften is how they get there.

Company
Riften
Earned intelligence for every company.
We're building Riften, a gateway that sits in front of a company's AI traffic. It automatically routes requests to the lowest-cost model that can handle them, prioritizing open-weight models we host. Over time, it accumulates data to train private models tailored to each company, so they own and compound their own intelligence. It starts as a cost-saving API gateway and becomes a stack companies control instead of renting AI.
San Francisco, CA, USA. The company is and will be based in San Francisco.
San Francisco is where most of our early users are and is the center for AI infrastructure work. It's also where we live and work.
