TJL Defence
Defence intelligence, from the first sensor to the last decision.
Purpose-built for operations that cannot fail, and designed, built and run in the Kingdom.
Who we are
A Saudi deep-tech company that makes the unseen visible.
TJL takes its name from تَجَلّى: to manifest, to become visible. One algorithmic engine runs across energy, mobility and defence, and what it learns in one domain strengthens the others.
Saudi deep techDesigned and built in the Kingdom, for Vision 2030 priorities.
AI in hardwareData-driven algorithms running in adaptive hardware, in real conditions.
Research at the coreA research-led team, with engineering at the edge.
One algorithmic engine · every domain
TJL Defence
From sensing to action, one chain.
Each works on its own and alongside the systems already in service. Together they connect every unit, see and predict, understand every link, and coordinate the fleet.
Sovereign by design
Edge first, no cloud dependency
Fits the systems in service
Built in the Kingdom
Communication infrastructure
One sovereign mesh. Nobody external can switch it off.
TJL owns and operates the mesh inside the Kingdom, independent of commercial networks. Defence units run their own missions on it, and it heals itself around any lost node.
- No SIMNo commercial operator anywhere in the chain
- Self-healingTraffic finds a new route the moment a node is lost
- Isolated by keysEach unit's data can be read only with its own keys
- Multi-purposeSensors, trackers and control on battery-powered devices, on one mesh

Communication infrastructure
Many units on one mesh. Each sees only its own.
Every unit has its own keys, its own data and its own API. TJL Vectora, a mini C4 platform, gives each one its own operating picture and alerts.

Coverage is the capability, built base by base, corridor by corridor.
Fixed units are served from the first installation, which justifies the buildout. Mobile units are fully served as the footprint grows.

Trajectory prediction
See it, track it, and know where it is going next.
TJL Intelligence detects and tracks targets with a camera on an embedded board. Each target's distance, direction and speed are measured and its path predicted, on the device.

Trajectory prediction
All the intelligence on the device.
From the vision sensor to the response, every step runs on one embedded processor. A reasoning layer then answers questions about each session.

Most targets came from the left: 7 of 12 between −60° and −30°. The nearest approach was 18 m.

Communication decoding
Closed protocols, decoded by AI agents from their own traffic.
Legacy and foreign-vendor systems often speak a language only their own consoles understand. TJL listens to the link, works the language out, and brings every message into national C2. Nothing is sent to either device.
~30 minfor one AI agent to learn a closed protocol from its traffic
100%of captured messages decoded and rebuilt byte for byte
0messages sent to either device: capture is receive-only
Communication decoding
Every closed link becomes a source you control.
The output is a decoder with its tests and its specification, not a model in the packet path. It can read the link, and it can speak it.
- DeterministicPlain code runs on the traffic; no AI sits in the packet path
- Listen-onlyNothing is sent on the link, so the systems on it keep running exactly as they are
- Vendor-independentIntegration no longer waits on the original vendor or its documentation
- CumulativeEach decoded protocol joins a library, so the next one is faster

- Decode by difference

A lead agent proposes each finding. A second agent, with fresh context, tries to break it before it counts.

UAV mission engine
Intelligence above the fleet, not inside each drone.
Mission goals become tasks. Each task goes to the right UAV by capability and position, every path is flyable, and the plan changes the moment a UAV is lost or new orders arrive.

UAV mission engine
Four layers. One chain of command.
The engine sits between the operator and the fleet, and drops into existing C2 through its API. No rip-and-replace.

- 2
Predict
Its path is predicted to cross the fence line.
- 3
Alert
The alert crosses the sovereign mesh to the perimeter unit, under its own keys.
- 4
Confirm
