Proven before it ships
Every product passes its own test set on real work before anyone uses it. You will build the gates, not work around them.

Join us.
Build the gold standard.
At Aurifex, small teams build AI that people trust with skilled work: proven on real work before it ships, open about where its answers come from, and always in the user’s control. Bring what makes you, you, and help make it.

[ 01 ] // Work at Aurifex
Seven products.
One standard.
Every Aurifex product is built by a small team that owns it end to end. Pick the work you care about: hospitals, learning, music, books, medical education, job seekers or jewelry.
[ 02 ] // Life at Aurifex
How we work
is what we build.
The standard our products meet is the standard we hold ourselves to.
Sources over guesses
If our AI says it, it shows where it came from. When it is unsure, it says so and asks.
People stay in control
Nothing important happens without a person’s say: Truefill never presses Submit, Aurifex Healthcare drafts and the case manager decides.
Private by default
We collect the least we can, keep it safe, and never sell it.
Built for everyone
Accessible from the first design, so the people who need it most can use it.
Own the outcome
Small teams own a product end to end, from the first interview with a user to the numbers after launch.
