• Belgian family offices allocate an average of 27% of portfolios to private equity, and 42% plan to increase that exposure.

• Belgium's three largest family-controlled investment companies (GBL, Sofina, Cobepa) manage combined NAV exceeding €28 billion.

Family Office Brussels: Landscape Overview

Brussels serves as the nerve center for family offices in Belgium. The city hosts the country's largest listed investment holdings, its most active SFOs, and a growing cluster of independent MFOs. Belgium's position as the EU capital gives these offices direct access to European regulators, cross-border deal flow, and a talent pool fluent in Dutch, French, and German.

The market is expanding fast. Sixty percent of surveyed Benelux family offices launched since 2010. Belgium's historically favorable tax regime (no capital gains tax, no wealth tax) has attracted ultra-high-net-worth (UHNW) families from the Netherlands and France. Several Belgian offices maintain satellite presence in Luxembourg, Geneva, Paris, and London to serve cross-border clients.

What sets Belgium apart is the range of office structures. Traditional SFOs like Verlinvest sit alongside publicly listed family-controlled vehicles such as Sofina and GBL. Independent MFOs like Agami and Alena compete with virtual family office (VFO) arrangements and advisory-only models like Buyck Family Advisory Office. This variety gives wealthy families more structural options than most European markets of comparable size.

Top Belgian Family Offices in Detail

GBL (Groupe Bruxelles Lambert)

Belgium's largest family-controlled holding company manages a €14 billion portfolio split between listed blue chips and direct private assets. GBL holds stakes in global names like adidas, Pernod Ricard, SGS, and Umicore on the public side. Its private portfolio includes healthcare platform Affidea, bicycle maker Canyon, and eyecare group Sanoptis.

GBL Capital, the firm's indirect private equity arm, adds a third layer of broad asset mix. Families and institutional investors seeking wide allocation through a single listed vehicle will find GBL's structure unique in continental Europe. The holding trades on Euronext Brussels with a market capitalization of €10 billion and offers a 6.6% dividend yield as of late 2025.

Sofina (Boël Family)

The Boël family controls roughly 55% of Sofina through a consortium of holding entities, preserving family oversight of a €9.8 billion investment platform. Sofina deploys patient capital as minority and growth-stage allocations in consumer, digital, education, healthcare, and sustainable supply chain companies.

A team of 80 professionals, including 33 investment specialists, operates from Brussels with offices in Luxembourg, London, and Singapore. A recent co-investment in Biobest, a biocontrol company focused on sustainable pest management, shows how Sofina blends wealth preservation with forward-looking sector bets. Roughly 93% of its portfolio sits in unlisted companies, placing it among Europe's most committed private market allocators.

Cobepa

European entrepreneurial families assembled through holding company Cobehold back Cobepa, which manages over €5.1 billion in net asset value. The firm provides permanent capital with flexible investment horizons, partnering with management teams in growing private companies.

CEO Jean-Marie Laurent Josi leads operations from Brussels, with a second office in New York. Cobepa's model appeals to families seeking private equity exposure without the forced exit timelines of traditional PE funds. Originally a subsidiary of Banque Paribas, the firm regained independent, family-backed ownership through a management buyout.

Verlinvest (de Mevius Family)

Ninth-generation AB InBev shareholders, the de Mevius family channels generational wealth through Verlinvest, an evergreen investment vehicle with over €1 billion in managed assets. The firm's thesis centers on "consumer revolutions," targeting growth-stage FMCG, health, and lifestyle brands.

Its portfolio reads like a list of breakout consumer names: Oatly, Vita Coco, Tony's Chocolonely, Mutti, Blue Tokai Coffee Roasters, and Epigamia. In 2025, Verlinvest participated in a €75 million Series C round in The Eye Foundation, a healthcare platform. A team of 71 professionals, including 21 investment partners in Brussels, Mumbai, and Singapore, gives the office global sourcing reach that few European SFOs match.

The Nest (Thermote Family)

Climate-aligned food and agriculture is The Nest's sole focus, with $500 million dedicated to this mandate. Led by Els Thermote, the office invests in companies tackling food system resilience, including Quick Organics, Olombria, Agricarbon, Propagate, and Monarch Tractor.

Investment Director Anouk Schoors oversees a portfolio spanning direct equity stakes, venture capital rounds, and fund-of-funds commitments like Biotope Ventures II. The Nest also develops net-zero buildings within a 300-kilometer radius of Brussels. Tech founders and next-generation wealth holders focused on values-driven capital will find this office's mandate among the most specific in Europe.

Agami MFO

Bank independence defines Agami. Francois Simon and Laurent de Swarte founded this MFO in 2006, and it now serves wealthy families from offices in Brussels, Paris, Lyon, and Lisbon. Its service menu spans wealth planning, financial advisory, succession planning, real estate management, charitable giving, and private equity advisory.

Agami also offers private secretary services, an unusual addition reflecting its full-service approach. With over 30 employees, it ranks among the larger independent MFOs in Belgium. Families seeking a single point of coordination for advisors, banks, and estate structures (without bank product conflicts) will find Agami's model compelling.

Alena

Active private investors run this Brussels-based MFO, bringing direct business experience to client portfolios. Registered with the National Bank of Belgium since February 2000, Alena combines portfolio management with financial engineering, estate planning, and consulting.

The executive committee, led by Benoît Delahaut and Li Min Choi, invests capital alongside clients rather than merely advising on allocations. This operator-investor model suits families who want their wealth managers to share personal financial risk. With fewer than ten employees, Alena serves a deliberately limited number of clients, prioritizing depth of relationship over volume.

Infinitum Family Office

Research-driven, data-intensive wealth management sets Infinitum apart from Belgium's established MFOs. Founder Joachim van der Meiren left his role as Head of Family Office at Degroof Petercam to launch the firm in February 2024. He holds a Certificate in Quantitative Finance and completed Harvard Business School's Leadership Principals Program.

Financial Manager Saskia Speleers and Technology & Operations Manager Jelle Winters round out the three-person team. Infinitum focuses on strategic asset allocation, consolidated reporting, and private asset oversight. It is not currently accepting new clients, a deliberate choice to maintain service quality during its buildout phase. UHNW families seeking an analytical, institutional-grade approach to private equity and private debt monitoring should watch this office as it grows.

Investment Trends Shaping Brussels' Wealth Platforms

Direct Deals and Co-Investment Growth

Belgian family offices allocate an average of 27% of portfolios to private equity, and 42% of Benelux offices plan to increase that exposure. The shift runs toward direct deals and co-investments rather than fund-only strategies. Cobepa's permanent capital model and Verlinvest's direct brand buyouts illustrate this preference for hands-on ownership over passive fund commitments.

Climate-Aligned and Impact Capital Deployment

Forty percent of Benelux family offices are active in impact investing, and one in three families runs its own foundation. The Nest is the clearest example, deploying $500 million into food systems and agri-tech. Verlinvest's emphasis on "purpose-led brands" reflects a broader pattern where even commercially driven Belgian offices integrate environmental criteria into deal selection.

Consumer Brands and AgriTech as Sector Bets

Belgian industrial dynasties leverage their heritage in consumer goods and agriculture. Verlinvest's portfolio of global FMCG brands builds on the de Mevius family's AB InBev roots. The Nest channels the Thermote family's focus into agri-tech startups and sustainable food supply chains. These sector concentrations give Belgian offices a distinct identity compared to the generalist approach common in London or Zurich.

Navigating Belgian Tax and Regulatory Shifts

Belgium's proposed 10% capital gains tax on financial assets could reshape family office structuring. The Cayman tax legislation already targets foreign low-taxed entities used by Belgian residents. MFOs offering investment advice may need registration with the National Bank of Belgium, as Alena has maintained since 2000. EU Sustainable Finance Disclosure Regulation adds reporting obligations that smaller offices must now budget for.

How to Evaluate a Family Office in Belgium

Bank independence is the first question to settle. Several Belgian MFOs, including Agami and Alena, position their separation from banking groups as a core value proposition. An office affiliated with a bank may steer clients toward proprietary products. Ask directly whether the office earns distribution fees or retrocessions from third-party fund managers.

Regulatory registration provides a baseline credibility check specific to Belgium. Alena's registration with the National Bank of Belgium since 2000 sets a benchmark. SFOs managing only family assets face lighter requirements, but any office advising external clients should hold appropriate authorization. Request evidence of compliance with anti-money laundering rules and UBO Register obligations.

Scope clarity matters more in Belgium than in larger markets. "Family office services" can mean Infinitum's research-driven private asset oversight, Buyck's real estate development and advisory, or Intuitae's full estate planning and family governance package. Define what you need before engaging (consolidated reporting, succession planning, or direct deal sourcing) and verify whether the office delivers that function in-house or outsources it.

Cross-border structuring capability is a Belgium-specific evaluation factor. The country sits at the intersection of Luxembourg, the Netherlands, France, and Switzerland, each with different tax treaties and wealth structures. Intuitae's four-city presence (Brussels, Paris, Geneva, Luxembourg) illustrates the multi-jurisdiction coordination that Belgian UHNW families often require. Belgium's evolving tax landscape, including the proposed capital gains tax and Cayman tax rules, makes tax advisory quality a critical differentiator.

Which Family Office Fits Your Needs?

UHNW families with €500 million or more in liquid assets seeking institutional-grade broad exposure should explore GBL, Sofina, or Cobepa. All three offer permanent capital structures and professional management teams with decades of track record. GBL and Sofina are publicly listed, providing liquidity and transparency that private structures cannot match. Cobepa appeals to families who prefer private, relationship-driven engagement.

Business owners planning a liquidity event will find full post-exit structuring at Agami or Alena. Both offer estate planning and succession advisory alongside investment management. Agami's cross-border offices in Paris and Lisbon serve entrepreneurs with assets in multiple European jurisdictions. Alena's operator-investor model adds accountability, since the team puts personal capital alongside clients.

Next-generation wealth holders drawn to values-aligned investing have two distinct options. The Nest's climate-focused mandate suits families committed to food systems and sustainable agriculture. Verlinvest appeals to those who want commercial returns from consumer brands with social impact. For families needing multi-country estate coordination between Belgium, Luxembourg, and Switzerland, Intuitae's four-office network provides dedicated expertise. Newly wealthy families seeking a fresh, research-driven approach should track Infinitum as it builds its client base.
