The journey started in 1936 when Byggnadsupplysningar (Byggfakta) was established in Stockholm, Sweden. Parts of the operations were moved to Ljusdal during the 1970’s and eventually, also the head office was moved to Ljusdal in 1985.

The company was acquired by Thomson International in 1988 and then sold to Segulah and Sture Wigart in 1996. In 2000 the company was acquired by Reed Business Information.

During the fall of 2001, Docu Group was founded through a merger of three companies, Swedish CityMark, Swiss Schweize Baudocumentation and German Baumarktvorschung. The companies had operations within information services, although from three different business areas, real estate (SE), product (CH) and project (DE). Docu Group acquired Byggfakta from Reed Business Information in 2009.

Over the years Docu Group has grown significantly through a combination of organic growth and acquisitions. In 2014 Docu Group was divided into two units, one unit operating in the German-speaking countries and one Nordic unit acquired by Segulah.

In September 2017, Segulah and minority stakeholders signed an agreement to sell 100% of DOCU Nordic to Stirling Square Capital Partners.

In 2020 the company changed name to Byggfakta Group.

In September 2020, Stirling Square Capital Partners sold 42% of its stake in Byggfakta Group to TA-Associates.

In 2021, Byggfakta Group expanded geographically with the acquisitions of UK based NBS and Glenigan.
