Precision Edge AI
& Sensor Fusion
Physical AI Proven in Production.
Built With Experts in the Loop.
Most Edge AI Projects Stall.
88% of AI pilots failed to reach production in 2025 (IDC). Off-the-shelf ML frameworks promise performance but collapse in real-world deployment. Gathering the right training data becomes a struggle, leading to false positives that compromise your product quality. Without proper expertise, projects go over budget, miss deadlines, or never leave the pilot stage.
221e begins with your device, not a generic ML framework.
Instead of relying on massive datasets and hoping AI figures it out, we combine experts in the loop with small, high-quality data. Physics-informed feature extraction enables lightweight ML models that work efficiently on constrained devices. Custom pre- and post-processing around the edge AI handles sensor limitations and refines the output for real-world conditions.
The result is reliability that generic platforms can’t achieve.
You get accurate physical AI and sensor fusion solutions backed by expert support that gets you from prototype to production.

Why Our Customers Chose Us
“Thanks to the collaboration with the 221e team we have been able to translate into practice our vision involving the detection of movement in patients/athletes. They have always been very quick and attentive in providing useful feedback for the proper development of the project. We are planning to further develop our collaboration in order to enhance our potential and bring continuous innovation to our products.”
Dott. Mario Gabbrielli – CEO, Dott. Viktor Terekhov – CSO
“In the case of 221e, I greatly appreciated their IoT expertise. They have developed a miniature MUSE sensor that adapts to multiple contexts and provides a series of environmental data that, when properly analyzed, can create a lot of value in different contexts.”
Guido Cendali Pignatelli – Open Innovation Manager
“Thanks to the 221e team for contributing their expertise in smart sensor systems, their technical advice about the appropriate software for the project and the extraction and analysis of the data”
Paolo Sabbioni – Founder
