APROPLAN and GenieBelt are two of the fastest-growing “Software as a Service” (SaaS) companies in the construction industry. Recently, we made a huge move by merging together and now we are a 120+ contech scale-up — called LetsBuild — and we are ready to change the industry! Our clients will now benefit from our married expertise of in-depth project planning and quality assurance.

Together, both companies are used in thousands of projects in more than 35 countries and have offices in Copenhagen, Brussels and Lodz. GenieBelt and APROPLAN had a combined growth of 75% in 2018 and in the beginning of 2019, our team grew by 100%. We are still growing rapidly and the ambition is to continue this development. If you work with us, you will get the opportunity to be part of a company with big potential and velocity.

In LetsBuild, we believe in clear commitments and respectful disagreements, and we support each other.
