European Search Fund Research: IESE & INSEAD Studies

The European search fund ecosystem has grown from a handful of pioneering searchers in the late 2000s to over 100 active searches annually, making it the fastest-growing ETA market outside North America. Two institutions have been instrumental in documenting, researching, and accelerating this growth: IESE Business School in Barcelona and INSEAD in Fontainebleau. Their research provides the most comprehensive data available on European search fund performance, deal structures, and market dynamics. This article synthesizes the key findings from their studies and explores what they mean for searchers, investors, and the future of ETA in Europe.

IESE Business School research program

IESE has been the intellectual home of European search funds since Professor Rob Johnson and the IESE entrepreneurship faculty began studying the model in the early 2000s. Today, IESE's International Search Fund Center (ISFC) produces the most cited European search fund research and serves as the hub for the European ETA community.

History and methodology

• IESE published its first European search fund study in 2012, covering a small sample of searchers who had launched between 2004 and 2011. Since then, the study has been updated approximately every two years with expanding datasets.
• The research methodology mirrors the Stanford study approach: surveys of searchers and investors combined with analysis of financial outcomes (IRR and return on invested capital) for completed search fund cycles.
• IESE also produces case studies on individual European search funds, providing detailed narratives of search processes, acquisitions, and post-acquisition operations. These cases are used in MBA classrooms globally.

Key findings from IESE research

• European search funds have achieved aggregate returns broadly comparable to the US model, with median IRRs in the 30–40% range for completed acquisitions — though the dataset remains smaller and less mature.
• The conversion rate from funded search to completed acquisition has been similar to the US (approximately 65–75%), though European searches tend to take slightly longer due to fewer broker-intermediated deals and more complex regulatory environments.
• Industry selection in Europe mirrors the US: business services, healthcare, technology-enabled services, and niche manufacturing dominate successful acquisitions.
• The IESE research highlights that European searchers who focused on a single country and language market performed better than those who tried to search across multiple countries simultaneously. The exception is the Nordics, where cultural and linguistic similarities allow for effective multi-country searches.

INSEAD search fund research and alumni impact

INSEAD has played a complementary role to IESE in developing the European search fund ecosystem. While IESE has led in formal research output, INSEAD's contribution has been primarily through its alumni network and its role as a launchpad for searchers across Europe and beyond.

Research contributions

• INSEAD faculty have published research on search fund investor behavior, comparing how European and US investors evaluate search fund opportunities and structure their investments.
• The school's research has explored the role of MBA programs in preparing search fund operators, finding that the combination of general management education and entrepreneurial training is strongly correlated with post-acquisition performance.
• INSEAD has also studied self-funded search models in Europe, which have grown faster than traditional funded searches in several markets.

Alumni network impact

• INSEAD alumni have launched search funds across France, Germany, the UK, the Netherlands, the Nordics, and increasingly in Africa and the Middle East.
• The school's global alumni network provides searchers with cross-border connections that are particularly valuable in Europe's fragmented market.
• Several INSEAD alumni have become prominent search fund investors, creating a virtuous cycle of capital, mentorship, and deal flow within the European ecosystem.

European vs. US performance comparison

Comparing European and US search fund performance requires careful caveats: the European dataset is smaller, less mature, and spans a shorter time period. That said, the available data reveals both similarities and differences.

Returns

• Aggregate US search fund returns have been approximately 33% IRR and 5.5x return on invested capital over the four-decade history of the model (per the Stanford 2024 study).
• European returns appear broadly similar for completed acquisitions, though the smaller sample size makes the data less statistically robust. The top quartile of European search funds has achieved returns comparable to the best US outcomes.
• European search funds have a slightly lower loss rate than US funds, potentially because European searchers tend to be more conservative in deal selection and leverage.

Deal sizes

• Average European search fund acquisition sizes have been smaller than US deals, typically $3M–$10M enterprise value compared to $5M–$20M in the US.
• This gap is narrowing as the European market matures and larger search fund investors enter the market.
• Smaller deal sizes in Europe partly reflect the smaller average size of European SMEs and lower EBITDA multiples in certain markets.

Time to close

• European searches typically take 18–24 months from fundraising to acquisition, compared to 15–21 months in the US.
• The longer timeline reflects fewer intermediated deal processes, more complex regulatory approvals in some jurisdictions, and the need to navigate different legal and tax frameworks across countries.

Growth trajectory of European search funds

The growth of European search funds has been remarkable, following a trajectory that mirrors the US model approximately 15–20 years behind.

• Before 2010: fewer than 10 search funds were active in all of Europe. The model was virtually unknown outside of IESE and a small community of early adopters.
• 2010–2015:growth accelerated as IESE research gained visibility and early European success stories demonstrated the model's viability. Approximately 10–20 new searches launched annually.
• 2015–2020:the model reached a tipping point. Multiple MBA programs began teaching search fund courses, dedicated European search fund investors emerged, and the number of new searches grew to 30–50 per year.
• 2020–present: over 100 search funds are now active annually across Europe. The ecosystem includes dedicated investors, search fund conferences, peer networks, and a growing body of operational best practices adapted for European markets.

Key European markets by activity

Spain

Spain was the first European market to embrace search funds, driven largely by IESE's location in Barcelona. Spain benefits from a large SME sector with many family-owned businesses facing succession challenges, relatively lower valuations than Northern Europe, and a growing ecosystem of local search fund investors. It remains the most active European search fund market by volume.

France

France has emerged as the second-largest European search fund market. The country's enormous SME sector (over 3 million small businesses), combined with a wave of baby boomer retirements, creates significant deal flow. French search funds benefit from supportive government programs for business succession and a well-developed professional services ecosystem. However, labor regulations and social charges create complexity that searchers must navigate carefully.

Germany

Germany represents the largest untapped opportunity in European search funds. The Mittelstand — Germany's famed small and medium-sized enterprise sector — includes tens of thousands of family-owned businesses with revenues between €2M and €50M. Many face succession challenges as founders retire without family successors. However, German business culture favors long-term relationships and gradual transitions, which can extend search timelines. Deal multiples tend to be higher than in Southern Europe.

United Kingdom

The UK has a well-developed SME acquisition market but search funds compete more directly with established private equity firms, family offices, and management buyout structures. UK search funds benefit from English-language deal documentation, familiar legal frameworks, and a deep pool of professional advisors. London business schools (LBS, Oxford, Cambridge) have become important feeders for UK search fund operators.

Nordics

The Nordic countries (Sweden, Denmark, Norway, Finland) have developed a distinctive search fund ecosystem characterized by cross-border searches, strong business school networks (Stockholm School of Economics, Copenhagen Business School), and high-quality SMEs with strong corporate governance traditions. Nordic search funds benefit from cultural similarities across countries, making multi-market searches more feasible than elsewhere in Europe.

European investor landscape evolution

• In the early days, European search funds relied heavily on US-based investors who understood the model. Today, a growing cohort of dedicated European search fund investors has emerged, including former search fund CEOs who have successfully exited and now invest in the next generation.
• European family offices have become increasingly active search fund investors, attracted by the model's alignment of interests and hands-on approach to value creation.
• Several dedicated search fund funds have been raised in Europe, pooling capital from institutional and individual investors to provide systematic search fund financing.
• Cross-border investing remains common, with US investors continuing to participate in European search funds and European investors beginning to invest in US searches.

Differences in deal structure

European search fund deals differ from their US counterparts in several important structural ways, reflecting differences in financing markets, legal systems, and business culture.

• More seller financing.European deals frequently include a larger proportion of seller financing (30–50% of the purchase price) compared to US deals. This reflects both the sellers' willingness to support the transition and the relative scarcity of acquisition lending for small deals in some European markets.
• Lower leverage. European search fund acquisitions typically use less bank debt than US deals. The absence of an SBA-equivalent program in most European countries means that commercial bank lending is the primary debt source, and banks tend to be more conservative in their lending criteria.
• Earnout structures. Earnouts are more common in European deals, partly because they bridge valuation gaps and partly because European sellers tend to be more willing to maintain involvement post-sale during a transition period.
• Legal complexity. Each European country has its own corporate law, employment law, tax code, and regulatory framework. Cross-border deals add additional complexity related to transfer pricing, withholding taxes, and regulatory approvals.

Cultural and regulatory factors

European search fund operators face cultural and regulatory considerations that do not exist in the US market.

• Employment protections. Most European countries have stronger employee protections than the US, including restrictions on termination, mandatory severance, works council consultations, and collective bargaining agreements. These protections affect the speed and cost of post-acquisition organizational changes.
• Language and culture. Operating in a non-English speaking market requires fluency in the local language and deep cultural understanding. Many successful European searchers are either native to their target market or have lived there extensively.
• Relationship-based deal sourcing. In many European markets, business sales happen through personal networks rather than broker-intermediated processes. Building relationships with accountants, lawyers, and industry associations is even more important than in the US.
• Tax optimization. European tax structures are complex and vary significantly by country. Holding company structures, tax-efficient jurisdictions (Luxembourg, Netherlands), and country-specific incentives can meaningfully impact after-tax returns. Engaging experienced tax advisors early is essential.
• Data privacy (GDPR). The General Data Protection Regulation adds compliance requirements for due diligence, data handling, and post-acquisition technology implementations that do not exist in the US context.

Future outlook and growth projections

• The European search fund market is expected to continue growing at 15–25% annually for the foreseeable future, driven by increasing awareness, a maturing investor ecosystem, and the massive succession wave as baby boomer business owners retire.
• Germany is widely viewed as the next major growth market, with the potential to become the largest European search fund market by volume within a decade.
• Self-funded and partially-funded search models are growing faster than traditional funded searches in Europe, particularly in markets where the traditional model is less well-known.
• Cross-border roll-ups — acquiring businesses in multiple European countries to build pan-European platforms — represent a unique opportunity that does not exist in the more homogeneous US market.
• As the European ecosystem matures, returns may moderate as increased competition drives up acquisition multiples. Early movers in less-developed markets (Central and Eastern Europe, Italy, Portugal) may capture the highest risk-adjusted returns.
