illicocash
illicocash was established in 1992 as the single-family office for the Coisne family, whose wealth originates from Sonepar, the world's largest privately held electrical distribution company. The family has held majority control since 1969, when Henri Coisne led a management buyout from the founding Lambert family. Today, Marie-Christine Coisne-Roquette chairs Sonepar and her brother François Coisne serves as a principal within the family office structure. The office deploys capital across a deliberately broad mandate designed to reduce concentration risk from the core industrial holding. Asset classes include direct private equity, real assets — predominantly commercial real estate in European gateway cities — and commitments to external private equity and venture capital funds. The direct investment arm has historically favored European mid-market companies with established cash flows, particularly in business services, industrial technology, and distribution-adjacent sectors. The office constructs its portfolio through a mix of proprietary direct deals, co-investments alongside long-standing GP relationships, and select fund commitments. The geographic focus centers on Western Europe, with France, Germany, and the Benelux region receiving the majority of deployment, supplemented by opportunistic allocations in North America. illicocash operates with a lean professional team characteristic of European single-family offices that guard their privacy carefully. The group does not publicly disclose its total assets under management, operating headcount, or deployment cadence, consistent with the Coisne family's low-profile posture across their business and investment entities. The office maintains no public-facing digital footprint beyond a placeholder website at illicocash.com. No linked charitable foundation is formally tied to the office, though the family's philanthropic activities flow through the broader Coisne family ecosystem, including educational and cultural patronage within France. What distinguishes illicocash structurally is its unusually tight integration with an operating business that itself remains private. While many family offices diversify away from a sold enterprise, illicocash manages a perpetual balancing act: preserving liquidity to support Sonepar's growth and acquisitions — the company has completed over 100 acquisitions since 2000 — while steadily compounding a separate portfolio of uncorrelated assets. This dual mandate, sustained across multiple generations of family leadership, produces an investment posture that favors patient, control-oriented capital and long-duration holds over rapid portfolio churn.

Frequently asked questions
Who controls investment decisions at illicocash?
Investment decisions are steered by the Coisne family's principals, with Marie-Christine Coisne-Roquette and François Coisne holding the most senior oversight. The office likely employs a small internal investment team handling direct deal execution, with family members retaining final approval on commitments above a certain threshold. The family's governance model, refined through five decades of Sonepar ownership, emphasizes consensus-driven capital allocation.
Where does the underlying wealth come from?
The wealth originates entirely from Sonepar, the world's largest privately held electrical distribution company. The Coisne family led a management buyout of Sonepar in 1969 and has retained majority control since. The company generated €33.3 billion in revenue in 2023 and operates across 40 countries, providing the foundation for the family's investment office.
Does illicocash invest in venture capital or only later-stage deals?
illicocash's direct investment activity skews toward established, cash-flowing businesses in the European mid-market, consistent with a family office rooted in industrial wealth. The office does commit to external venture capital funds for exposure to earlier-stage innovation, though its own direct underwriting favors control and co-control positions with proven business models.
How is illicocash related to Sonepar operationally?
illicocash operates as a fully separate legal and operational entity from Sonepar, though the family's ownership of both creates natural structural ties. The office's investment portfolio is managed independently of the operating company, a firewall designed to protect the family's diversified wealth from Sonepar's corporate liabilities and strategic decisions.
Which regions does illicocash prioritize for investment?
The office concentrates on Western Europe, with deep coverage of France, Germany, and the Benelux region. Sonepar's geographic footprint across Europe and the Americas provides the family with operational intelligence in those markets, though illicocash's direct investments skew heavily toward European opportunities. North American exposure is pursued primarily through fund commitments and select co-investments.
Does the family maintain a separate philanthropic vehicle?
The Coisne family's charitable giving is conducted through personal and family-directed channels rather than a named foundation publicly tied to illicocash. Their known philanthropic interests include educational institutions and French cultural preservation, reflecting the family's long-standing ties to French civic life.
Has illicocash's investment strategy changed as Sonepar has scaled?
As Sonepar grew through over 100 acquisitions since 2000, the family office's diversification mandate became more urgent. The office has progressively expanded its private equity and real asset allocation to reduce correlation with the industrial distribution business, while still maintaining sufficient liquidity to support Sonepar's own acquisition pipeline — a persistent structural tension that shapes the portfolio's composition.
