Most transport companies manage 6+ separate systems.

Teltonika, OEM data, TMS, ERP, planning software, driver apps — all separate. No single source of truth. No quick answers. Dependent on software vendors.

D4DC is the single source of truth for all your transport data: one connection, one model, always up to date.

Built for every fleet stakeholder

• Fleet operators — Manage all fleet data in one place: vehicles, drivers, orders and telemetry.
• Software providers — Add telematics to your product without building or maintaining integrations.
• Telematics service providers — Launch new services on top of one standardised data layer.
• Hardware manufacturers — Bring your devices to market faster with a ready-made data platform.

Connect once. Use everywhere.

When data is centrally and standardised available, dashboards, portals and AI applications can be built in hours instead of months.

1. Connect — Teltonika, OEM link (rFMS), app GPS, MQTT, REST API — everything flows directly into D4DC without custom integration work.
2. Standardize — Speed, GPS, fuel, engine state — consistently defined regardless of source. You never ask two systems the same question and get two different answers.
3. Activate — CO₂ reports, driver coaching, planning integration or a WhatsApp assistant — plugins that work immediately on your data.

WhatsApp Fleet Assistant — ask questions in plain language

No app to install. No dashboard to open. Your dispatcher sends a WhatsApp message and D4DC pulls live data from the hub — GPS position, fuel level, order status, weekly mileage — and replies within a second.

Activate only what you need

D4DC Core collects, standardises and stores your data. On top of that, activate exactly what you need — safety, location enrichment, compliance and analytics — all on the same data layer.

• Overspeeding detection
• Reverse geocoding
• RDW vehicle data
• Tachograph data analysis
• Fleet hub aggregation
