Bringing scientific rigor to audit
The audit profession relies on judgment, experience, and methodology. We add mathematical proof.
Swiss Engineering
AssureTwin is designed and built in Zurich, Switzerland — a global center for financial services, precision engineering, and formal methods research. We combine deep audit domain expertise with techniques from computer science: finite state machines, temporal logic, and synthetic data generation.
Our core engine, DataSynth, is a Rust-native workspace of 19 crates that generates complete audit simulations at enterprise scale. Every workflow is formally verified. Every artifact is traceable. Every proof is exportable.
