Reggeborgh Groep

Reggeborgh Groep manages the private wealth of the Wessels family, whose fortune originates from VolkerWessels, the Dutch construction and infrastructure conglomerate. The family office, based in Rijssen in the eastern Netherlands, operates as the family's primary investment vehicle. CEO Henry Holterman has served on the boards of both VolkerWessels and Reggeborgh, anchoring the office's governance within the family's industrial roots. The group maintains a deliberately low public profile, consistent with northern European family-office norms. The firm invests across private equity, real estate, and infrastructure, with a clear preference for direct stakes and long-duration holds. Its portfolio history includes significant financial-sector positions: Reggeborgh was a co-shareholder alongside J.C. Flowers & Co. in NIBC Bank, and the two largest private shareholders agreed to sell their combined stakes in September 2023 (per public record, 2023). In a more recent transaction completed in July 2025, ING Group acquired Reggeborgh's 17.6% stake in Van Lanschot Kempen. The firm's geographic focus is concentrated in Europe, and it tags Energy Transition & Renewables, Healthcare Services, and Cybersecurity as active sector interests. Its investment structures span direct co-investments and special-purpose vehicles. Team scale is not publicly disclosed, but board interlocks trace a network into Dutch blue-chip industrials. Henry Holterman has held supervisory board positions at Wolters Kluwer and Océ. Advisors to the group have included former Telstra chairman John P. Mullen and Telstra non-executive director Niek Jan van Damme. Through family principal Inge Wessels, Reggeborgh supports Stichting WensAmbulance Oost-Nederland, a wish-granting ambulance charity. In July 2025, the firm closed the sale of its Van Lanschot Kempen stake to ING Group, converting a legacy financial holding into liquidity that signals a potential reallocation phase. Reggeborgh operates with the structural advantage of permanent family capital — no external LP constraints, no fixed deployment windows. That architecture lets it hold positions through full cycles, a posture visible in multi-decade relationships like the co-investor link to Johannesburg Consolidated Investments dating to 1970. Succession governance runs through the Wessels family and Holterman's dual board seats, binding the investment office tightly to the operating-company legacy rather than spinning it off as a standalone asset manager.

Frequently asked questions

Who runs investment decisions at Reggeborgh Groep?

CEO Henry Holterman leads the firm and sits on the board of directors. He has been associated with Reggeborgh since at least 2007, when he was listed as a board member in VolkerWessels' annual report. Holterman also held supervisory board roles at Wolters Kluwer and Océ, linking the family office to senior Dutch industrial governance networks.

Where does the underlying wealth come from?

The wealth originates from the Wessels family's founding and majority ownership of VolkerWessels, a major Dutch construction, infrastructure, and engineering group. Reggeborgh serves as the family's investment vehicle, distinct from the operating company.

Is Reggeborgh structured as a single family office or does it operate more like a holding company?

It is a single family office, but its concentration in direct private equity stakes and long-duration holds gives it a holding-company texture. The firm does not market funds to external investors and deploys permanent family capital. Its board interlocks with VolkerWessels reinforce the hybrid feel, though it functions as the Wessels family's private investment arm.

Does Reggeborgh participate in fund commitments or only direct deals?

The firm's confirmed investment types include direct co-investments, special-purpose vehicles, and direct stakes across private equity, real estate, and infrastructure. Its history with NIBC Bank and Van Lanschot Kempen points to direct balance-sheet positions rather than fund-of-funds activity, though no public source confirms or rules out selective fund commitments.

What was Reggeborgh's relationship with J.C. Flowers in NIBC?

Reggeborgh and J.C. Flowers were the two largest private shareholders in Dutch merchant bank NIBC. In September 2023, they agreed to sell their combined stakes, ending a multi-year co-investment in the financial-services sector.

How does Reggeborgh handle the family's philanthropic interests?

Through family principal Inge Wessels, Reggeborgh supports Stichting WensAmbulance Oost-Nederland, a charity that grants wishes to seriously ill individuals via a specialized ambulance service. The philanthropic activity is branded under the family office rather than operated through a separate foundation structure.

What does the 2025 Van Lanschot Kempen divestment signal?

In July 2025, ING Group acquired Reggeborgh's 17.6% stake in Van Lanschot Kempen. The sale converted a legacy financial holding into liquid capital. While the firm has not publicly stated its redeployment plan, the transaction suggests portfolio reshaping toward its tagged sectors of Energy Transition & Renewables, Healthcare Services, and Cybersecurity.
