Building the future of construction
Kalvsvik Labs builds AI agents for construction companies. The agents read tender documents and contracts, monitor tenders and find subcontractors, so you can spend your time on what matters most.

Why Kalvsvik exists
Construction shapes the world we live in. It builds the homes we return to, the schools our children learn in and the infrastructure that keeps society moving. It is one of the largest industries in the world, yet one of the least digitised. Much of the work still runs on binders, PDFs and long email threads.
Every project begins with documents. A single tender package can hold hundreds of files, from drawings and technical specifications to contracts and administrative provisions, and all of it must be read against the clock. Requirements hide in appendices, risks in the fine print and deadlines in emails. What slips through shows up later, in the estimate, the schedule and the margin.
The expertise to handle this already exists. Experienced estimators, project managers and purchasers know exactly what to look for. What they lack is time. Too much of it goes to reading and searching, and too little to judgement, planning and building.
At its core this is a data problem, and data problems are exactly what AI is built to solve. Kalvsvik's agents read every document, structure the data and show exactly where each requirement and risk comes from. People stay in control of every decision. The agents do the groundwork.
We believe the next great leap in construction will come not only from new materials and new machines, but from making better use of the knowledge the industry already has. That is why we are building Kalvsvik. So that the people who build can spend less time on paperwork and more time creating what lasts.
Reshaping construction, one bid at a time.
The team behind Kalvsvik
We are a team in Stockholm that combines experience from finance, artificial intelligence and construction. Together we are building the AI that will change how the industry works, from the first tender document to the finished building. We develop Kalvsvik close to the contractors it is made for, and we are growing.
Help us build the future of construction
We are looking for curious and driven people who want to change how an entire industry works. If you want to help build something that lasts, we would love to hear from you.
