Auxilium Capital acquires Software Improvement Group

19 June 2017

Amsterdam, 19 June 2017 – Software Improvement Group (SIG) announces that Auxilium Capital has acquired the company together with entrepreneurial investors Robert Pijselman and Luc Brandts, and management of SIG. Supported by the experienced team of investors, SIG will be able to expand globally and continue to capture growth opportunities by helping its clients fundamentally improve the architecture, security and performance of the software enterprise applications that support every aspect of their businesses.

Auxilium has acquired the company from its founders Mr. Wildvank, Mr. Kuipers and Mr. Klint. Financial details are not disclosed.

SIG, founded in 2000 as a spin-off from Centrum Wiskunde & Informatica (CWI), specializes in tool-based advice on software quality including architecture and security. Serving clients in Europe, the United States, and Asia, SIG provides its prominent customer group the visibility they need to address their current software risks and prevent future risks from occurring. Additionally, SIG is able to continuously monitor the performance and output of software development teams, leading to improved transparency on costs and quality.

Erik Oltmans, CEO at SIG comments on the transaction: “We are excited that we have found a new growth partner for SIG. We see unique opportunities for SIG, and are eager to further build upon what has been so intelligently created by its founders since its inception in 2000. SIG is grateful for the strong basis that has been built by them. This change of ownership is a logical step in the history of SIG following the gradual withdrawal of its founders from operations over the past years.”

For this transaction, Auxilium Capital has teamed up with Mr. Robert Pijselman and Mr. Luc Brandts, two highly experienced software entrepreneurs. Pijselman and Brandts previously grew Bwise into a global leader in Governance Risk and Compliance software and subsequently sold it to Nasdaq. Both are on the board of PQR, EV Box, 5W, Recruitee and several other companies, and previously at Blue Cielo. Pijselman and Brandts co-invested alongside Auxilium, and will form the new supervisory board of SIG together with Jeroen Nienhaus from Auxilium. Pijselman and Brandts state: “We are very proud to be the new business partners of SIG. As software people, we’ve known SIG for a long time and highly appreciate the reputation of SIG and its professional team of highly regarded consultants. SIG has a truly unique profile and possesses all ingredients to become the world-class standard in measuring software quality and auditing of software”. “Making the connection between capital, leadership and knowledge is a clear example of the Auxilium way of working”, adds Jeroen Nienhaus of Auxilium.
