Careers
Join the atelier
We are a small, deliberate team headquartered in San Francisco, building the pipeline that tailors private models for companies worldwide. If you like craft, ownership and a high bar, read on.
What the work is like
Made to measure
A model should fit the company that wears it. We tailor, we do not sell off the shelf.
Owned, not rented
The weights belong to the customer. We hold the craft, not the garment.
Cleared the bar
Nothing deploys until it beats the base model on an eval built from your own standard.
Quiet by default
Your data trains your model only. Privacy is the setting, not the upsell.
