Construction is one of the largest industries in the world, yet it is inefficient, wasteful, and incredibly complex. Rising cost pressure and increasing complexity are pushing the industry to its limits. At comstruct, we are on a mission to fundamentally change how construction companies operate and we are looking for people who want to build that future with us.

comstruct develops autonomous AI agents that reimagine the entire material procurement process, from requisition to posted invoice. Our platform takes over repetitive and error-prone tasks across the material flow, enabling construction companies to focus on what truly matters: building. Backed by a €12.5M funding round with investors such as Google Ventures and 20VC, we are now entering our next growth phase and are looking for exceptionally driven and ambitious individuals to help scale our product.
