Paper-based workflows, fragmented tools, and minimal digital adoption create massive inefficiencies, costing around €400B every year and impacting the daily work of 15+ million professionals. Grafit is building the Operating System for Construction: a modern, all-in-one SaaS platform that simplifies and streamlines every step of a construction project — from quoting to commissioning, including purchasing, task management, and execution.
