Pronestor receives strategic investment to help accelerate growth


Lyngby, 11 November 2022: 


Pronestor, has accepted strategic investment from PSG, a leading growth equity firm partnering with software and technology-enabled services companies to help accelerate their growth.

Pronestor, which has built an established position in the Workspace Management Solutions market over the past 20 years, now joins the Sign In Solutions group- a global provider of cloud-based visitor management and risk mitigation software backed by PSG. As
part of this international group, Pronestor will gain broader geographical reach and be able to offer additional solutions inline with Sign In Solutions’ Visitor Management 2.0 (VM 2.0) vision.

“Sign In Solutions has a clear focus on the Workspace Management industry, where we believe the growth potential is considerable.” said Karsten Busck, CEO of Pronestor. “It is the perfect timing for us to join the group to reach new global markets and expand our solutions even further, which are targeted at the hybrid workplace. With Sign In Solutions as our parent company, we will be supplied with the necessary resources to be able to expand and enter a global community of related companies; thereby gaining easier access to the international market as well as a wider product palette within our field.”

Karsten Busck joined Pronestor in 2018, and since then the company has gone through a professionalization that has resulted in annual growth rates of 25-30 percent. In 2020, Pronestor received capital from the venture fund Dico, which among other things made it possible to add new muscles to the development department. A tangible result is Pronestor’s newest product, Pronestor Workspace, which is an administration solution with an app interface tailored for
hybrid workplaces.

Dan Harding, Chief Operating Officer of Sign In Solutions, said, “We are thrilled to provide added value to our customers and partners through this strategic acquisition. We will continue to strive to shape and lead the visitor management space through our VM 2.0 vision, with an aim towards reducing risk for our customers and helping them adapt to the challenges of the ever-changing workplace.”

Pronestor sells its solutions in Europe, the USA and Asia through partners. The largest market is Denmark, which accounts for 50 percent of sales. The customers include many large commercial companies and public authorities, including Deloitte, TDC and a number of public institutions.
