Buysse & Partners

Buysse & Partners was established in Antwerp in 2008 by Managing Partner Frank Buysse. The firm operates as a multi-family office and independent investment house, aggregating capital from a network of Belgian families and entrepreneurs. Its founding principle is alignment: every member of the Buysse & Partners team invests personally in the vehicles it manages. The firm’s strategy rests on two pillars — private equity and real estate. On the private equity side, Buysse & Partners pursues direct buyout investments in mature, profitable small and medium-sized enterprises (SMEs) headquartered in Belgium with clear growth potential. Confirmed portfolio companies include forklift distributor Mabo Group and intellectual property firm Brantsandpatents (which merged with Merk-Echt and Brndpwr). The firm has co-invested alongside institutions including PMV, LRM Capital, SmartFin Capital, and Velocity Capital in Ancoa Software, and with Korys, Quest for Growth, and Capricorn Partners in biotech spin-off BlueBee. Its real estate strategy is divided into two dedicated funds: an iconic real estate fund targeting architectural landmarks in the Benelux, and a residential fund focused on consolidating the private rental market in Belgian city centers. Notable properties include Amsterdam’s Insinger building on the Herengracht, Rotterdam’s Las Palmas building, and the CBR building in Brussels. The firm also operates as an engaged landlord; tenants in its Antwerp BP Tower include Delen Private Bank, BNP Paribas Wealth Management, and Waterland Private Equity. Buysse & Partners maintains a lean structure anchored in Antwerp with a network of investment partners across Belgium and the Netherlands. The firm is a member of Private Capital Belgium, and Partner Dimitri Herbosch is active in the SFO Alliance, a global peer network for single-family offices, indicating an outward-facing posture despite its local investment focus. In 2024, the firm raised over €100 million in fresh capital to further professionalize the residential rental market. Another recent transaction saw the sale of the Zilveren Toren in The Hague to the Dutch Central Government Real Estate Agency (Rijksvastgoedbedrijf), demonstrating realized exits from its iconic property fund. The firm’s structural differentiator is its dual alignment mechanism. Unlike standard commingled funds, Buysse & Partners requires its full team to co-invest personal capital into every deal, and pools capital from entrepreneur-investors who often bring operational expertise to portfolio companies. The cross-pollination between its real estate and private equity teams — managing buildings like businesses and advising portfolio companies on their own property strategies — creates a feedback loop that generic investment houses in the region lack.

Frequently asked questions

How is Buysse & Partners structured differently from a traditional private equity fund?

Buysse & Partners operates as an independent, multi-family investment house rather than a blind-pool fund. It pools capital on a deal-by-deal basis from a network of Belgian families and entrepreneurs. Critically, every member of the Buysse & Partners team personally co-invests their own capital into each transaction, creating an alignment structure where the investment team bears the same downside risk as its limited partners.

Does the firm invest only in Belgium, or across the broader Benelux region?

The firm’s private equity strategy is concentrated on mature, profitable SMEs headquartered in Belgium. Its real estate strategy, however, spans the entire Benelux region. The iconic property portfolio includes landmarks in Amsterdam, Rotterdam, and The Hague, in addition to holdings in Antwerp and Brussels, while the residential fund is focused on consolidating rental assets in Belgian city centers.

What is the firm’s history with the BlueBee investment, and who co-invested?

Buysse & Partners backed BlueBee, a Delft University of Technology biotech spin-off, in a consortium of co-investors that included Korys, Quest for Growth, Capricorn Partners, Heran Partners, and Delft Enterprises. The asset was later sold to Circet, providing an exit from the firm's rare non-Belgian private equity position.

What real estate strategies does Buysse & Partners deploy across its two funds?

The firm operates two distinct real estate funds. The iconic real estate fund acquires architectural landmarks in the Benelux — such as the Insinger building on Amsterdam’s Herengracht and the CBR building in Brussels — leveraging their unique character to attract premium tenants. The residential fund acquires and consolidates rental properties in Belgian city centers, with an explicit mission to professionalize the fragmented private rental market. In 2024, the firm raised over €100 million to scale this residential strategy.

Who leads the firm’s investment decisions and relationship management?

Managing Partner Frank Buysse founded the firm and leads its strategic direction. Partner Dimitri Herbosch, who holds an LL.M. from Duke University School of Law and degrees from the University of Antwerp, is a key principal driving deal execution and investor relations. The firm’s partnership model emphasizes that these senior leaders, alongside the entire team, commit personal capital to every investment.

Does Buysse & Partners engage with external professional networks or peer organizations?

Yes. The firm is a member of Private Capital Belgium, the country’s industry association for private equity and venture capital. Partner Dimitri Herbosch is also involved with the SFO Alliance, an international peer network for single-family office principals, which supports knowledge-sharing on governance and direct investing outside the traditional fund management circuit.

How does the firm realize value from its iconic real estate assets?

Buysse & Partners generates returns through active asset management and selective divestment. In a recent example, the firm sold the Zilveren Toren in The Hague to the Rijksvastgoedbedrijf, the Dutch central government’s real estate agency. While holding, the firm manages buildings to attract high-quality tenants; its Antwerp BP Tower, for instance, houses BNP Paribas Wealth Management and Waterland Private Equity.
