AI-native back office for construction companies and property developers
reebuild is a Vienna-based vertical AI platform that automates the commercial back office of construction companies and project developers. It reads incoming invoices, delivery notes, order confirmations and e-invoices line by line, turns them into structured data, matches documents automatically and supports invoice approval, cost management and material tracking, with a mobile app for capturing delivery notes on site. Founded in 2022 by Alexander Kornell, with Matteo Cimadom and Luca Papay as co-founders, it serves customers in Austria and Germany. In October 2026 it raised a €3 million seed round led by Fortino Ventures, with Rise PropTech, CuriosityVC and Hansmann Family Office participating.
