SPEXANT
Spec-driven software development that keeps AI under control
Atostek delivers specification-driven software development using Spexant, our AI framework for regulated, safety-critical, and long-lived software. Spexant keeps the engineering chain connected so AI agents can accelerate work without breaking traceability, human oversight, or audit readiness. Teams see what has been specified, implemented, verified, and what is still missing.
Atostek has spent 25 years building software in environments where things cannot afford to quietly break. Spexant is the result of that experience — not a response to a market trend, but a precise answer to what regulated and safety-critical software development actually demands.
