We offer a cloud-based and AI-powered Building Management System. With our predictive room control technology your commercial building will consume 20-40% less heating energy while improving the user comfort. Our AI technology learns the thermal behaviour of each room in the building solely from measurement data and uses this knowledge to proactively optimise building control. As a spin-off from the Urban Energy Systems Lab at Empa and the Automatic Control Lab at ETH Zurich, we are closely connected to leading research and innovation. Our solution can be installed within just a few hours. Owners of commercial existing buildings – such as real estate companies, corporates, SMEs, or the public sector (cities, municipalities, etc.) – typically achieve a return on investment within 2 to 5 years.

Unser Ziel bei FINABRO ist es, allen dabei zu helfen, HEUTE das Richtige zu tun, um MORGEN einen sicheren und komfortablen Ruhestand zu erreichen. Mit Blick auf die führenden Rentenmärkte der Welt bedeutet „alle“ zu erreichen, dass wir uns auf betriebliche Altersvorsorge konzentrieren: Wir haben es uns zur Aufgabe gemacht, Europas führende Vertriebsplattform für Altersvorsorge aufzubauen. Ursprünglich aus Österreich, haben wir Bürostandorte in Wien und Berlin. Unser großartiges Team aus 25 motivierten Personen arbeitet hart daran, zur Lösung des europäischen Rentenproblems beizutragen: ein Problem, das wir als vergleichbar herausfordernd betrachten wie den Klimawandel, da es langsam, aber stetig zunimmt und jetzt Maßnahmen erfordert – auch wenn seine Auswirkungen noch weit entfernt scheinen.

ICO-LUX ist der deutsche Marktführer für Dokumentenforensik und Automatisierte Echtheitsprüfung von Dokumenten. Unsere Mission ist es, Fälschern, Betrügern und Abzockern das Leben schwer zu machen. Wir sind darauf spezialisiert, Dokumente auf ihre Echtheit zu prüfen - vollautomatisch. Täglich werden in Deutschland Millionen von Dokumenten per Post, gescannt per eMail-Anhang oder als App-Foto verschickt. Die meisten Absender haben ehrliche Interessen. Doch Papier ist nicht fälschungssicher. Betrüger versuchen, die automatisierte Verarbeitung von Dokumenten auszunutzen, indem sie diese zum eigenen Vorteil manipulieren - und schaden so der Allgemeinheit. Unser Kernprodukt ist ICO.Fraud, die Betrugserkennungssoftware für Versicherungsunternehmen basierend auf Bildern von Belegen wie bspw. Smartphone-Fotos von Rechnungen oder gescannten Bestandsdokumenten.
