Show the working
Every loss estimate is checked against what happened afterwards, and you see the verdict.
About
A risk desk for a private portfolio.
Aureum Frontiers is a small company in Amsterdam. We build Sentinel so an investor who runs their own portfolio can see what it could lose, test it against a crisis, and check whether the estimate held up.
Why we started
Portfolio apps report what you made. Sentinel estimates what you could lose, and checks the estimate.
The few that try do not show their working. Sentinel started as an institutional risk engine. We cut it down to the questions a private investor asks and kept the part that matters most: the check on our own numbers.
What we hold ourselves to
Four rules, built into the product.
01
02
Same inputs, same answer
Run Sentinel twice on the same holdings and you get the same numbers, every time.
03
Read-only
Sentinel can see your holdings and cannot move them.
04
Your data stays yours
Holdings are encrypted while stored (AES-256-GCM). Export or delete everything at any time.
