Keep the model in step.
Connect approved systems through event feeds or scheduled updates. Preserve time, provenance and version history. Show stale, missing and conflicting information, so an old model never silently passes for the present.
Polydeuces
Living operational counterparts that connect what is observed, what is modelled and what could change.

What we build
Living operational counterparts that connect what is observed, what is modelled and what could change.
Represent how the institution works.
Connect services, assets, resources, obligations and dependencies in an inspectable operational model. Distinguish observed facts, inferred relationships and assumptions. Domain owners can challenge and correct the representation.
Rehearse changes across connected models.
Use Icarus to branch a versioned twin into bounded scenarios. Couple validated operational, statistical or physical models where appropriate. Compare cascading effects, competing explanations and uncertainty before committing resources.
Learn where the model was wrong.
Compare expected behaviour with observed outcomes. Detect drift, investigate disagreement and propose revisions. Test and approve a new model version before it informs operations; preserve the evidence behind the change.
Connect twins without surrendering control.
Our frontier is a federation of institutional twins: services, municipalities and infrastructure working across approved interfaces. Each participant governs its data, model and permissions. Shared scenarios depend on explicit agreements and compatible models.
Turn intelligence into accountable action.
Let authorised teams inspect a scenario, select a response and track its consequences. Solon governs model and tool access. Separate scenario exploration from operational execution, with approvals, source links and a recoverable decision history.
Built around your operation
Start with one institution, one decision and a bounded system. Define the authoritative sources, update cadence, model boundaries, permitted processing and operators. Extend to additional services or partners only when the interfaces, authority and evidence support it.
What we validate together
Agree freshness and coverage requirements; replay historical events; compare model behaviour with observations and existing methods. Evaluate sensitivity, uncertainty, failure modes and expert acceptance. The model must also show where it cannot support a decision.
Where it becomes useful.
Public services Rehearse a service reform before rollout.
If demand, staffing or a procedure changes, where could pressure move next?
- 01 / THE INPUTS
- Aggregated demand, service capacity, process stages, deadlines and authorised rules. Start with one service and agreed operational boundaries.
- 02 / THE WORKFLOW
- Maintain a current service model, test alternative staffing or process assumptions and trace dependencies. Compare projected queues and workload with subsequent observations.
- 03 / THE HUMAN DECISION
- Help the responsible administration compare a phased rollout, resource allocation and escalation options.
- The control that matters
- Officials retain policy and operational authority. The twin does not determine individual eligibility or produce a universal model of citizens. Expert validation and lawful data access define its scope.
- What success could be measured against
- Model freshness, ability to reproduce known service behaviour, forecast error where applicable and the time needed to compare feasible changes.
Regional resilience Trace disruption across essential services.
How could heat, flooding or an infrastructure outage affect the services that depend on it?
- 01 / THE INPUTS
- Approved asset maps, service dependencies, capacity data, maintenance events and validated environmental models.
- 02 / THE WORKFLOW
- Connect infrastructure and service models. Explore cascading effects and alternative responses, showing the assumptions and uncertainty inherited from each model.
- 03 / THE HUMAN DECISION
- Support continuity exercises, contingency planning and investment priorities across authorised partners.
- The control that matters
- Operators retain control over sensitive infrastructure information. Models support planning and exercises; emergency decisions follow the competent authority and established procedures.
- What success could be measured against
- Dependency coverage, reproducibility of exercises, agreement with observed incidents and clarity of response trade-offs.
Healthcare Understand capacity as a connected system.
What happens to services when beds, staff, equipment or supplies become constrained?
- 01 / THE INPUTS
- Authorised operational aggregates, capacity, equipment availability, stock and service schedules, with identities excluded where unnecessary.
- 02 / THE WORKFLOW
- Connect hospital operations in a bounded model. Rehearse demand and availability changes, compare responses and update assumptions against actual service behaviour.
- 03 / THE HUMAN DECISION
- Help hospital teams prepare capacity and logistics plans with dependencies and limitations visible.
- The control that matters
- This scope concerns operational planning. Clinical decisions, patient prioritisation and any medical-device functionality require separate assessment and authority.
- What success could be measured against
- Reliability of the operating picture, scenario accuracy where validated, planning effort and expert acceptance.
Finance & industry Give exposures an operational counterpart.
Which linked obligation or asset could turn a local disruption into a wider constraint?
- 01 / THE INPUTS
- Approved positions, commitments, cash flows, assets, capacity and contractual dependencies, adapted to the organisation.
- 02 / THE WORKFLOW
- Keep a versioned operating picture and connect it to validated scenario tools. Test compound changes without altering live positions or operational plans.
- 03 / THE HUMAN DECISION
- Let treasury, investment or industrial teams compare feasible responses and inspect the evidence behind them.
- The control that matters
- Models and permissions are specific to the institution. Investment decisions and changes to production or payment systems require separate authorisation.
- What success could be measured against
- Reconciliation coverage, repeatability of analysis, model performance against observations and time to prepare a decision.

A delivery is late.
What should we do next?
Follow one illustrative example from a supplier update to a decision a person can explain and approve.
- Eridanos
Connect the evidence
A supplier reports a two-day delay. Eridanos brings that update together with stock records and customer orders, preserving the source and time of each record.
- Ariadne
Link cause and consequence
Ariadne links the delayed part to the orders that need it, their deadlines and the warehouses holding alternatives. This is the shared model of how the operation works.
- Polydeuces
See the operation as it stands
Polydeuces brings the connected model into a digital twin: which orders are exposed, what stock is available and when the picture was last updated. Missing information stays visible.
- Icarus
Compare possible responses
Icarus tests waiting, moving stock or using another supplier against agreed costs, deadlines and capacity. The team can compare the options and see the assumptions behind them.
- Solon
Ask, understand, then approve
A planner asks Solon which response meets the deadline. It explains the comparison using permitted evidence and tools. The planner approves any proposed action before it reaches an operational system.
The result: one decision, with its evidence and trade-offs.
Polydeuces is the operational workspace. It can bring together the connected data of Eridanos, the relationships of Ariadne, the scenarios of Icarus and the governed AI assistance of Solon. We select and build the capabilities your use case needs.
An illustrative workflow, not a live client deployment. Integrations, access controls, models and approval steps are agreed and validated for each project.One service first. Connected institutions next.
An institution that can examine its own model.
Our ambition is a network of sovereign twins that can rehearse shared futures while each institution retains control over its data, models and decisions.
Polydeuces maintains the evolving counterpart. Icarus explores its possible futures. Ariadne structures its meaning. Solon governs the use of AI. Eridanos connects the evidence.
Proposed capability. Illustrative animation with synthetic relationships. Each twin is scoped, developed and validated with the institution.
