Concept · Three.js
Our own concept, not client work: a real-time 3D apartment is the interface. Run a scene, dim a light, switch day to night, or watch the bath humidity sensor raise an alert and the fan clear it. Web and mobile share one model and one state.

Direct answer
99 Francs develops digital twin product surfaces for physical spaces, buildings and operational systems.
This service is for teams that need a working digital twin frontend, 3D or spatial viewer, smart building dashboard, IoT visualization layer, control interface, MVP demo or data-connected product surface that makes the physical system easier to monitor, explain and act on.
Deliverables
What the digital twin development scope can include.
The scope focuses on the visible software layer: how users see the space, read system state, compare data, control modes and understand what changed.
Data and sensor layers
Temperature, occupancy, energy, lighting, equipment, alerts or custom operational data visualized in a readable product interface.
Controls and simulation states
Mode switches, speed controls, scenario views, status panels, filters, thresholds and safe interaction patterns for operators.
MVP and demo package
A focused prototype or launch-ready product surface that helps buyers, investors or internal teams understand the digital twin concept.
Best fit
Use this when the physical system needs a clear software surface.
The model exists, but users cannot operate it
We turn a 3D model, floor plan, BIM file or spatial dataset into product screens, controls and states people can actually use.
The dashboard shows data without context
We connect data to the space, asset or workflow it belongs to, so operators can understand where an issue is and what to do next.
The concept needs a credible demo
We build an MVP-quality interface that shows the twin, the data layers, the controls and the business value in one coherent flow.
The system crosses design and engineering
Digital twins need UX, frontend architecture, data-state thinking and visual hierarchy to move together from the start.
Process
Build the twin around decisions, not just the scene.
The process starts with the user job: what they need to monitor, compare, control, simulate or explain inside the physical system.
Map the twin scope
We define the physical space or asset, user roles, data layers, model inputs, critical states and the first operational decisions the twin must support.
Design the product surface
We shape the viewer, dashboards, controls, legends, alerts, empty states and responsive layouts before implementation gets expensive.
Develop the interface
We build the frontend surface with the right web stack, interaction states, reusable components and integration assumptions.
Prepare the demo or launch
We package the experience for stakeholder review, sales demos, pilot users or the next development phase with clear handoff notes.
No deposit. You pay when it works.
A digital twin is a custom build, so it runs in fixed-price phases and each one is paid only after you accept it. The full model is on how we work.

Make the physical system readable before adding more features.
Digital twin development is building a software representation of a physical space, asset or system so users can visualize state, inspect data, simulate scenarios, monitor operations and make decisions through a digital interface.
99 Francs can build the visible product surface: 3D or spatial viewers, dashboards, data layers, controls, states, filters, alerts, product demos and frontend-ready interfaces for digital twin products.
Yes, when the scope includes available APIs, IoT feeds or structured datasets. For early MVPs, 99 Francs can also build a realistic simulated data layer to validate the product experience before full integration.
No. The service can fit smart buildings, real estate, proptech, facilities, IoT products, energy dashboards, logistics surfaces and other physical systems that need a clearer operational interface.
