Lucien Digital Systems is a software company rooted in the practical realities of the installation industry. Founded by Jeffrey Barts in Rekken, it develops digital tools to make work easier for installers and help organisations manage buildings, energy and maintenance with greater clarity. Its approach prioritises real-world needs, modular connections and practical improvements over technology for its own sake.

The company’s portfolio includes customer portals that extend existing CRM systems such as Robaws, bringing customer communication, tickets, invoices and planning into one accessible space. Its BEMS.one platform connects building systems and supports energy and water management, including monitoring, automation and predictive maintenance. Related solutions include FlexControl Manager for thermal energy storage, AquaWatch for water quality and legionella risk monitoring, and SonarBuilding for predictive maintenance using vibration and acoustic analysis. Lucien also develops Installbot, a field app for installers, and OpenClaw, a set of specialised AI bots and Telegram systems. Beyond building technology, its brands include GeldwijzerNL, an iOS financial education app, and Aeruga, which publishes philosophical essays and audiobooks.
