About DemoStage

DemoStage builds demonstration simulators: a live, interactive stand-in for a complex system, built on your data, your look and your workflows, that a person drives in the room. We are Demo Stage Ltd., an Israeli company based in Herzliya.

The short version. Founded by military air controllers serving in reserves and full-stack software engineers. We build one simulator per customer, around the system they actually run, for defense tech, aerospace, and aviation and air traffic. Engagements start with a 20-minute call and a working scenario usually exists within days.

Who we are

The founders spent years managing real-time sky pictures under operational pressure, and years building production software. That combination is the whole premise of the company: the people scoping your simulator have sat in the seat the simulator is depicting, and can also ship the thing.

It means there is no ramp-up period on the vocabulary. C2 systems, radar and sensor telemetry, tracks and tasking, sector handover, rules of engagement, degraded modes - these are not terms we have to be taught before the first meeting is useful.

What a demonstration simulator is

It looks like your product or your operating picture, runs on the data you already hold rather than invented numbers, and reacts in real time to whoever is driving it. Someone in the room takes the controls, and every input moves the outcome while they watch. It is not a video, not a click-through prototype, and not a slide deck with animations.

It comes in three levels on one engine. A concept and technology demonstrator drives one system or one new concept live, and is the usual place to start. A unified scenario demonstrator puts several of your systems into one scenario on one screen, for teams who sell a portfolio. A unified scenario simulator shares one scenario across several systems and several screens at once, and is scoped with you.

The same engine also serves as a modeling tool for planners and operators: traffic on a road network, passengers through a terminal, movement through an airspace, built on your own trend data. It is illustrative modeling that strengthens a case, not a certified decision tool.

Who we build for

Defense technology, aerospace, and aviation and air traffic - organizations whose systems are hard to explain and expensive to misrepresent. The same engine serves adjacent mission-critical work: counter-UAS command and control, sensor fusion concepts of operation, airport and ground operations, and road and traffic decision layers.

We are a poor fit for general web or app development, for a static marketing site, or for off-the-shelf demo-automation tooling. Every build is made around one customer's system, never assembled from a template.

How an engagement runs

A 20-minute scoping call establishes what the simulator has to prove and to whom. We build the first working scenario in days rather than months, while the meeting, the tender or the decision is still open. The simulator is delivered as a product you own, with no expiry date and the first year of service included, and further scenarios are added to the same engine rather than rebuilt from scratch.

Delivery is normally a hosted environment on your own subdomain. Where the material cannot leave your estate, the same build runs containerised on your infrastructure or as a fully offline package for an air-gapped laptop.
