We build the layer
between a model and a job
Veltrix started in 2022 after watching three companies fail at the same task: getting an agent past the demo. The model was never the problem. The runtime was.
Our thesis
Every serious AI deployment eventually rebuilds the same six things: durable execution, tool permissions, memory, evaluation, observability and cost control. Each team builds them badly, once, under deadline. We build them once, properly, for everyone.
That means we are deliberately not a model company and not a framework. We are the runtime underneath — the part that decides whether an agent is allowed to issue a refund, what happens when a tool times out, and how you prove to an auditor what occurred at 12:04 p.m. on a Tuesday.
We sell to operators with a number to move, not to teams collecting demos. If a use case cannot be measured, we will say so and walk away.

How we work
- Measure or do not ship. Every launch has a number and a baseline.
- Boring where it counts. Novel models, conventional infrastructure.
- Write it down. Decisions live in documents, not in someone's head.
- Respect the on-call. If it pages a human weekly, it is not done.
Where we are
Remote-first across the United States and Canada; we hire where we can support the timezone.
Building something that has to work?
We are hiring engineers and researchers who prefer production to prototypes.
