Kungsmontage selects Yesper
AI that frees up time and enhances sustainability in construction projects
November 1, 2025
After over three decades as a partner in some of the nation's most complex construction projects, Kungsmontage is taking the next step in its digital journey. The company is now initiating a strategic collaboration with Yesper, the Swedish construction AI specialist whose platform reads millions of drawings, spreadsheets, and project contracts in seconds.
“We want our site managers and engineers to spend time on value-creating decisions – not searching for information in old binders. Yesper's construction-trained AI gives us the right answers quickly and helps us build both faster and greener,” says Christer Bjelkert, CEO of Kungsmontage.
Why Kungsmontage is Investing in AI
Since 1987, Kungsmontage has delivered turnkey and general contracting in Greater Stockholm and Mälardalen, covering everything from hospitals and schools to commercial properties. With more than 35 years of experience and specialization in structural completion, the company is now certified according to BKMA and operates with a clear focus on sustainability.
At the same time, the amount of documentation grows with each project. The need to quickly reuse knowledge, compare versions, and ensure compliance has never been greater – a perfect match for Yesper's industry-trained AI platform.
What Yesper Brings to the Table
Yesper's solution is specially trained for Swedish construction and infrastructure and understands AMA/AB/ABT, drawings, quantity lists, and Excel calculations. The result is a knowledge graph providing project teams with instant insights:
Find and summarize relevant parts of previous projects
Compare bids and drawing versions with one click
Generate ready-made templates, checklists, and change order documents in seconds
Everything is hosted in a closed Azure instance following GDPR and ISO 27001; the customer owns and controls their data, and nothing is used to train models.
The Journey Begins – From Startup to Full Rollout
The partnership begins with a joint workshop series where the companies prioritize use-cases with the greatest business and environmental impact. The first AI-driven workflows will be rolled out in November.
“Yesper was born from our experience scaling ideas at Spotify, King, and iZettle. Just as music became streamable, construction knowledge will become searchable and reusable,” says Peter Blom, founder of Yesper.
