The runtime for live decision logic.

Theseus is a deterministic, real-time platform for teams that run operationally sensitive logic in production. Governed, replayable, and auditable by design.

From fragmented change control.

A runtime built for governed, real-time decision logic.

Theseus ingests live inputs, executes deterministic logic modules, and produces traceable outputs — with built-in lineage, replay, and safe change control at every step.

Deterministic execution

Same inputs produce the same outputs. Always.

No hidden state, no silent divergence. Correctness is structural, not accidental.

Replayability and lineage

Every execution is replayable.

Every output is traceable to its inputs, logic version, and trigger. Incident analysis that took days now takes minutes.

The problem

Production logic is fragile. Change is slow. Audits are painful.

In most organisations, the decision logic that drives real-time operations — pricing, risk, limits, calculations — is fragmented across scripts, services, spreadsheets, and specialist engineers. It works until it doesn’t. Changes take weeks, touch too many teams, and leave no reliable audit trail. When something goes wrong, rebuilding what happened is manual, slow, and incomplete. This is not a tooling gap. It is a runtime gap.
