A communication software for the construction industry? In the highly fragmented construction sector, up to 100 companies are involved in a construction project. The idea of koppla is that construction sites and their contractors are connected. Crafts enterprises of all sizes and trades can collaborate on orders via the koppla software and track the progress of the orders in real time. Thereby construction companies - from the administration to the craftsman - can communicate over the software by means of pictures, messages, time registration, check lists and much more. koppla is up and working on construction projects ranging from 100€ up to 80.000.000€ with more than 30 construction companies on board.
