For anyone whose result has to be believed

The problem

Whatever your app does, members can always suspect it picked the winner.

With Veritrus

Send each draw through the Veritrus API. Every winner comes back with a proof link your members can check for themselves, so the suspicion has nowhere to land.

The problem

"Was that draw rigged?" Until now you could only take someone's word for it.

With Veritrus

Open the proof link and your browser re-checks everything: the locked entries, the public randomness, the draw itself. No trust in us, the platform or the organizer required.

The problem

Paying someone to draw on camera is slow and costly, and still doesn't stop the accusations.

With Veritrus

Pick a winner or shuffle a list with the free tools and share the proof link. Anyone can check it, now or years from now.

The problem

Disputes, complaints and audit questions long after the winner is announced.

With Veritrus

A permanent, independently checkable record of how each winner was picked, from entries locked in advance. (Whether a promotion is lawful where you run it is still up to you and your advisers.)

The problem

Selections and allocations that the people affected can challenge, and often do.

With Veritrus

Selections that are provably fixed in advance and unbiased, with a public record everyone affected can check, not just be told about.

The problem

Proving a sample wasn't hand-picked, to people who weren't in the room.

With Veritrus

Samples anyone can recompute, from public randomness and inputs locked beforehand, with a signed, logged record of exactly what was selected and when.
