## About

Jos Sluys established Saffelberg Investments after the 2007 merger of his HR-technology company ARINSO International with Northgate Information Solutions. The firm maintains a single-family-office structure that manages the proceeds from that exit. It operates from Gooik, Belgium, and commits capital on a long-term basis. Saffelberg allocates across venture capital and private equity. It participates in direct co-investments, SPVs and fund-of-funds commitments. Asset classes include software, life sciences and industrial technology. The firm has backed more than 40 companies that together generate over 1 billion EUR in revenue and employ 3,500 people. Investments span Europe with additional exposure through global venture and growth rounds. Confirmed holdings include positions in AI, Internet-of-Things and medical-diagnostics companies. The team comprises nine professionals with more than 100 years of combined corporate and entrepreneurial experience. Saffelberg maintains its sole office in Gooik. No additional vehicles such as foundations or operating businesses appear in public records. As of May 2023 the portfolio stood at 40 companies. Saffelberg’s structure ties investment decisions directly to the founding principal’s capital. This alignment removes external LP reporting cycles and allows indefinite holding periods. The office therefore favors control-oriented or large-minority stakes that support multi-year operational involvement.
