Gryphion

Gryphion is the single-family office of Rob Thielen, the founder and chairman of Waterland Private Equity, a major European investment firm. Based in Amsterdam, Netherlands, Gryphion serves as the private investment platform for the Thielen family, overseeing a portfolio that spans private equity, real estate, venture capital, and philanthropic interests.

Gryphion was established to manage and preserve the wealth accumulated from Thielen’s career in private equity, particularly following the success of Waterland, which has grown into one of Europe’s most respected and high-performing private equity firms. With a strong background in mid-market buyouts and growth investments, Thielen brings a rigorous and strategic mindset to Gryphion’s capital allocation decisions.

The office operates with a long-term investment horizon, seeking opportunities that combine stable returns with social and economic value creation. Gryphion’s portfolio includes direct investments in high-growth companies, co-investments alongside institutional funds, and diversified allocations across asset classes. It also maintains a presence in impact investing, with a focus on sustainability, education, and innovation.

In addition to investment activities, Gryphion supports philanthropic endeavors aligned with the Thielen family's values. These include contributions to cultural institutions, academic research, and community development initiatives both in the Netherlands and internationally.

Gryphion maintains a lean structure, relying on a small team of experienced professionals and strategic advisors. The family office emphasizes privacy and discretion, operating largely out of the public eye while maintaining strong governance and disciplined risk management practices.

As a modern European family office, Gryphion reflects the blend of entrepreneurial success and responsible capital stewardship. It embodies the next phase of wealth management for one of Europe’s most successful private equity figures, with a focus on legacy, purpose, and long-term value.
