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.

Is this you?
If you're behind Riften: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
