Family office
A practical guide to family offices: what they are, how they invest, how they differ from other investors, and why they are increasingly relevant for mid-market business owners in Spain.
The term family office is used with increasing frequency in the mergers and acquisitions world, yet its meaning remains unclear to many business owners. A family office is, in essence, the structure a high-net-worth family creates to manage its investments, wealth, and family affairs professionally and in an integrated manner.
Unlike private banking, which offers standardised financial products, or private equity, which invests third-party money with fixed timelines, a family office operates with the family's own wealth. This gives it a freedom of action that few investors have: it can invest without short-term return pressure, hold stakes indefinitely, and make decisions that prioritise family values over financial metrics.
For a mid-market business owner in Spain, understanding what a family office is and how it works is increasingly relevant, because family offices have become one of the leading buyers of businesses in the European mid-market.
Models
Created by and for a single family. It manages all wealth exclusively: financial investments, direct business investment, real estate, tax and estate planning, philanthropy, and administrative services. A minimum wealth of 50-100 million euros is typically required to be economically viable. Offers maximum customisation and confidentiality.
Serves several families, sharing structural costs and professional teams. It offers similar services to an SFO but with economies of scale. It is the most common option for wealth between 10 and 50 million euros. It can pool capital from several families to co-invest in larger deals.
A lean model in which the family coordinates external professionals (investment managers, tax advisors, lawyers) without creating a permanent structure. Suitable for more modest wealth levels or families who prefer a minimal structure. The coordination and integrated vision depend on the commitment of external professionals.
Investment
A family office's portfolio typically includes a combination of financial assets (fixed income, equities, funds), real estate, and direct business investment. It is this last category that is most relevant for mid-market business owners.
When a family office invests directly in a business, it does so with a different perspective to a private equity fund. It is in no hurry to enter or exit. It does not need financial leverage to generate returns. It can wait years for the right opportunity and, once invested, can hold the stake indefinitely.
This investment approach is known as patient capital, and it is the primary competitive advantage of family offices over other types of investors in the mid-market.
Comparison
Each type of investor operates with a different logic. Understanding it helps the owner choose the right partner.
PE invests third-party capital with 5-7 year timelines; the family office invests proprietary capital with no deadlines. PE seeks to maximise IRR; the family office prioritises intergenerational wealth preservation. PE typically leverages acquisitions; the family office prefers conservative structures.
Private banking manages financial wealth with standardised products; the family office manages comprehensive wealth with bespoke solutions. Private banking charges product commissions; the family office works with interests aligned to the family.
The strategic buyer acquires to integrate into its own operations, seeking synergies. The family office acquires to maintain the company as an independent entity, preserving its identity and culture.
Business angels invest in early-stage ventures with high risk; family offices prefer established businesses with stable cash flows. The amounts involved and the professionalisation of the process are significantly different.
Relevance for owners
Over the past decade, family offices have gone from being marginal players in the M&A market to becoming significant buyers of mid-market businesses in Europe and, increasingly, in Spain. Their relevance for business owners rests on three factors.
First, they offer an alternative to private equity for owners who want to sell but are not comfortable with the buy-and-resell model within a few years. Second, their patient capital allows them to offer continuity: retaining teams, culture, and identity. Third, being entrepreneurial families themselves, they understand the emotional and practical dynamics of succession in a way that an institutional fund cannot.
For many business owners with revenues between 3 and 50 million euros, a family office is the buyer that best balances price, terms, and respect for the company's legacy.
