About · Signet Stack Ltd

We build frontier-technology that proves itself.

Signet Stack Ltd is the company behind SignetStack Labs, where the hardest engineering, a post-quantum cryptographic core, is built once and inherited by everything we ship.

The model

One core, many products

The expensive, precision-engineered part, cryptography, safety, provability, operational maturity, never gets rebuilt. Each product is a specialist application of the same proven foundation, the way you swap the head on a precision tool but never the motor.

The Signet Data Trust Network Platform proves what happened to regulated data; SignetStack DXP brings the same rigour to digital experience; and Signetify makes it approachable as the governance OS for agentic commerce. More will follow, each on the same core. Two independent projects license the same core: Velocity Quant Technologies applies it to ultra-low-latency trading, and CalibrIQ to verifiable reliability ratings for autonomous financial agents on Solana. Each is separately owned and carries the “Secured by Signet Stack Core” endorsement once its integration is verified.

Principles

How we operate

01

Build the hard part once

Shared, proven engineering, never rebuilt per market.

02

Proof, not narrative

We replace claims with cryptographic evidence anyone can re-verify.

03

Honest by default

We state what's proven, what's planned, and what's not done yet.

04

Post-quantum from day one

The standards every record will need, built in now, not migrated later.

05

Govern as we grow

Human authority is retained; automation reduces toil, not accountability.

06

Compounding by design

Every core improvement lifts every product at once.

Signetify
A Signet Stack Ltd brand

Signetify™

Signetify is the governance operating system for agentic commerce. Humans and AI agents co-create and transact on the same storefront, through the same cryptographically-gated path. Only an authenticated human can hold a legally-binding signature. Built for the EU AI Act's August 2026 accountability requirements.
