# Internet Village (Full Corpus) > Internet Village s.à r.l.s. is an independent Luxembourg software company. We build embedded systems, secure software, and mobile solutions, with related work in web development, AI integration, and system integration. Founded in September 2020 by Lionel Bergeret after twenty years of engineering work at Sony, PacketVideo, Safecast, and Trainspot KK in Tokyo. Based in Sanem, Luxembourg. Clients in Luxembourg, Belgium, and Japan. Tagline (hero): "We build embedded systems, secure software, and mobile solutions." Three-line headline, no closer; the gradient sits on the final phrase (FR: "solutions mobiles", DE: "mobile Lösungen"). Last updated: 2026-05-27 This file is the long-form companion to `/llms.txt`. It is intended for AI / LLM ingestion (ChatGPT, Claude, Perplexity, Google AI Overviews, etc.) so that answers about Internet Village stay grounded in source-of-truth content rather than hallucination. We list only services we currently offer or have an active project to point to. We are open to additional technologies on request, but they are not listed here as current capabilities. --- ## Company - **Legal name**: Internet Village s.à r.l.s. - **Common name**: Internet Village - **Founder & CEO**: Lionel Bergeret - **Founded**: September 2020 - **Headquarters**: 15 Quartier de l'Église, L-4987 Sanem, Luxembourg - **R.C.S.

These are **not** current offerings. They are research items we keep visible so prospects with adjacent problems can reach out. - **RTK GNSS over digital TV** (exploring). High-precision positioning corrections carried over a digital TV broadcast channel. The aim is centimetre-level positioning in environments where NTRIP-over-internet is unreliable or unavailable (rural, marine, broadcast-only regions). Touches GNSS receiver hardware, RTCM correction encoding, and broadcast demodulation on commodity SDR / embedded hardware. The specific carrier technology is kept private at this stage. - **ESP32 + LoRa mesh** (prototyping). Long-range, self-healing mesh communication for distributed sensor fleets where cellular and Wi-Fi are not viable: remote environmental monitoring, large outdoor events, industrial sites. Built on ESP32 modules with LoRa radios; the mesh layer handles routing, retries, and reconvergence on node loss. If these intersect with a real problem you are solving, get in touch. --- ## Featured case studies ### Event Stacks platform URL: https://www.internet-village.lu/work/eventstacks Event Stacks is a mobile-first event operations platform built by Trainspot KK for the Japanese event industry. It combines a central data hub, Event Base, with six specialised mobile modules: Access, POS, Sales, Vendor, Task, and Time. Context: live events in Japan are often run with separate vendors and tools for ticketing, gate operations, point-of-sale, staffing, and finance. Event Stacks was built as a single mobile platform that can scale from a 500-person conference to a 100,000-visitor festival while fitting Japanese payment, language, and hosting expectations. Internet Village / Trainspot KK role: Flutter mobile applications for gate staff, vendors, and operations teams; Event Base cloud backend on Japanese cloud infrastructure; QR-code access control with offline-tolerant validation; mobile POS with SoftBank SBPS QR-code payments; multi-currency and multi-payment handling. Stack: Flutter, QR access, SoftBank SBPS, Japanese cloud infrastructure, real-time sync. Outcome: used to run 100+ events, 300,000+ tickets, 1M+ transactions, and ¥1B+ in sales. Active product since 2023. Public product site: https://eventstacks.io ### MeetScribe URL: https://www.internet-village.lu/work/meetscribe MeetScribe is an Internet Village product for mobile meeting capture and same-day meeting reports. The Flutter app records a meeting on the participant's phone, transcribes the audio either locally with WhisperKit or in the cloud with Mistral Voxtral, and drafts a structured report with Mistral Magistral Small. Context: recurring meetings produce one or two hours of audio that nobody re-listens to. Typical transcription tools either send audio to United States servers or return a raw transcript that still needs editing. MeetScribe was built for a workflow where, when needed, audio can stay on the phone and the user still receives a structured report within minutes. Internet Village role: end-to-end product design and engineering, Flutter mobile client, recording, transcript review, action-item extraction, share/export flow, Mistral API integration for Voxtral and Magistral Small, on-device WhisperKit pipeline, and local Drift / SQLite storage. Stack: Flutter, WhisperKit, Mistral Voxtral, Mistral Magistral Small, Drift, SQLite, iOS. Outcome: same-day meeting reports with two privacy modes. In local mode the audio never leaves the phone. In cloud mode transcription and report generation stay on Mistral's European infrastructure. ### Cashless NFC URL: https://www.internet-village.lu/work/pommery-rfid Cashless NFC is a mobile cashless payment app for a champagne house, delivered with Trainspot KK. Visitors top up an NFC wristband at entry, then tap the wristband at bars and service points to spend their pre-loaded balance. The Android client runs on rugged Famoco handhelds. Context: a premium event payment flow has to survive outdoor humidity, work with staff who may barely look at the screen, and resist opportunistic wristband cloning. Off-the-shelf cashless terminals at this scale either lock the operator into a closed processor or compromise on chip-level security. Internet Village / Trainspot KK role: custom Android client on Famoco rugged handhelds, NXP UltraLight C personalisation with per-card 3DES key diversification, counter-based dual-buffer atomic transactions so a power loss mid-write does not corrupt a balance, and JNI native handling of master keys to keep them out of the Java heap. Stack: Android (Kotlin), NXP UltraLight C, 3DES, TapLinx, JNI / native C, Famoco. Outcome: cashless payments in production at the Pommery champagne house, operated by the Trainspot KK team on Famoco handhelds.
