Built for the entire visitor journey
From real-time footfall to AI-driven scheduling, Ariadne covers the full operational stack. No cameras, no PII.
Why Ariadne
The Hybrid Fusion difference
Most analytics platforms still ride on cameras. Ariadne's Hybrid Fusion pairs anonymous signal sensing with Time-of-Flight depth. Same insights as a camera build, none of the privacy cost or the lens-by-lens install.

With Ariadne
Ariadne
Hybrid Fusion: signal sensing and Time-of-Flight
Privacy
Captures faces, bodies, and movement patterns.
Privacy
Anonymous device signals only. No PII ever stored.
Hardware
Cameras at every viewing angle. Cabling, mounting, lens upkeep.
Hardware
Compact signal sensors plus ToF units. Fewer pieces, smaller footprint, zero cameras.
Coverage
Only what each lens sees. Blind spots between cameras.
Coverage
Signal sensing reaches across whole venues. ToF validates counts at choke points.
Conditions
Lighting-dependent. Occlusion drops accuracy.
Conditions
Signal works in low light and crowded scenes. ToF stays accurate in any condition.
Compliance
GDPR / CCPA / EU AI Act friction. Ongoing legal risk.
Compliance
GDPR by design. TÜV-certified. EU AI Act ready.

Technology
Hybrid Fusion: depth plus signal
Two sensing technologies on a single edge device. Time-of-Flight depth sensing for device-independent counts at entry points. Our patented signal sensor for journey analytics across the venue. Sub-meter accuracy, no cameras.
Time-of-Flight
Pulses of infrared light measure distance to every visitor crossing an entry, exit, or choke point. Counts are device-independent: phone or no phone, every body is counted. No image is captured or stored.
- Counts every visitor, with or without a phone
- Holds up in low light and dense crowds
- No frames, no PII, GDPR by design
Patented phone signal sensing
Phones constantly broadcast signals as they search for connections. Our patented sensing technology detects every signal a device emits, even in airplane mode. Presence and movement are measured without ever collecting MAC addresses or device IDs. Identifiers are captured only if a visitor explicitly opts in.
- Detects every signal a phone emits
- 30 cm distance accuracy per detection
- No MAC capture by default, only on visitor opt-in
Hybrid Fusion combines depth-validated counts at entries with patented signal-based journey analytics across the venue. Every visitor counted, every path understood, zero personally-identifiable data captured.
How it worksHardware
Plug in our kit, or use yours
Compact people counters: our patented signal sensor for venue-wide flow plus Time-of-Flight units for entry counts. EaseLink when you'd rather route the Wi-Fi and BLE infrastructure you already operate. Same Hybrid Fusion insights, two install paths.

FAQ
Common questions.
Quick answers on Hybrid Fusion, privacy, and how Ariadne fits.
What is Ariadne?
Ariadne is a privacy-first people counting platform built on Hybrid Fusion sensing. We measure visitor flow across retail, airports, malls, and smart cities without cameras or facial recognition. Headquartered in Munich, Germany, with deployments in 32+ countries.
What is Hybrid Fusion?
Hybrid Fusion combines two sensing technologies on a single edge device. Time-of-Flight depth sensing handles device-independent counts at entry points. Our patented phone signal sensing technology detects every signal a phone emits, even in airplane mode, for journey analytics across the venue. Sub-meter accuracy without identifying anyone.
How is Ariadne different from camera-based people counters?
Camera-based counters capture biometric data and bring EU AI Act high-risk classification questions every time legal reviews a deployment. Ariadne's Hybrid Fusion architecture detects movement and signals, never appearance. No video, no facial recognition, no demographic inference.
Is Ariadne EU AI Act compatible?
Yes. Our architecture sits structurally outside Annex III high-risk categories because we don't capture or process biometric data. Our patented phone signal sensing technology measures presence and movement without collecting MAC addresses or device IDs. Identifiers are captured only when a visitor explicitly opts in (for example, through a guest Wi-Fi login). GDPR-native by design (Article 25).
Does Ariadne require visitors to install an app or log in?
No. Ariadne's default counting and flow analytics are fully passive. Visitors don't need an app, a login, or a Wi-Fi connection, and we don't collect MAC addresses or device IDs. Identifiers are captured only when a visitor explicitly opts in, and only for features that need them, like return-visit recognition or marketing attribution.
What venues does Ariadne work in?
Retail stores, shopping centres, airports, smart cities, digital signage networks, and any venue where visitor flow matters. Hybrid Fusion adapts to dense crowds, low light, complex layouts, and multi-zone environments.
