Family Office Nantes: Landscape Overview
Nantes anchors private wealth activity in western France's Grand Ouest corridor. The city's wealth ecosystem has grown steadily, driven by regional entrepreneurship and an expanding base of ultra-high-net-worth (UHNW) families. Established players like Xelis Family Office (20+ years) and Alias Finance (founded 2009) share the market with newer entrants such as O Patrimoine (launched 2020).
The dominant model is the multi-family office. Most local firms operate as independent MFOs registered as CIF (Conseiller en Investissement Financier) with ORIAS and the AMF. This French regulatory framework shapes how offices deliver investment advisory, insurance, and real estate services.
Many French wealth firms blend traditional patrimony management (gestion de patrimoine) with legal, tax, and succession planning under one roof. This approach contrasts with the Anglo-Saxon model, which typically separates these functions.
National expansion is reshaping the competitive field. Rothschild Martin Maurel chose Nantes for its Grand Ouest wealth office. Laplace consolidated regional operations by absorbing Primonial Gestion Privée Nantes.
Cyrus Herez, with 36 years of experience in gestion de fortune, also maintains a bureau here. These moves confirm that demand for holistic wealth preservation in this region is catching up to Paris.

Leading Offices: Detailed Profiles
Épitome Finance
Épitome Finance runs one of the most selective MFO platforms in western France, serving only 10 families with over €500M in consolidated patrimony. Co-founders Stéphanie Bocher and Jean-Charles Bodinier launched the firm in 2019 after careers at major private banks and international groups. Their model centers on a single client dashboard: monthly consolidated reporting with secure web access covering capital allocations, insurance, real estate, and legal matters.
The eight-person team handles everything from investment advisory to private secretariat work. Families with complex asset structures spanning multiple holding companies and real estate portfolios benefit most from Épitome's general secretariat function. This unit coordinates notaries, tax counsel, and bankers on the family's behalf.
Xelis Family Office
Xelis is the longest-running private wealth office serving this market, with over two decades of continuous operation. President Véronique Aubin earned inclusion in France's "100 qui font le patrimoine" list in January 2025 and gained recognition as a pioneer of gestion de patrimoine in December 2025. The firm's 10-person team operates from both Nantes and Paris.
Xelis offers fully self-hosted reporting tools for financial, budgetary, legal, and tax tracking. The firm also invests in innovative enterprises and private debt, making it one of the few local offices blending traditional patrimony structuring with direct investment activity. Its proprietary cloud systems, hosted and backed up on French servers, reflect a commitment to data security unusual for firms of this size.
Alias Finance
Alias Finance offers something rare in Nantes: a single independent office covering investment advisory, insurance, and real estate transactions. Co-founder Fabrice de Saint-Chaffray launched the firm in 2009 on a clear thesis: industrialized private banking fails wealthy clients. The six-person team deliberately limits its client base to ensure deep engagement with each family.
What sets Alias apart is its breadth of registrations: CIF for investment advisory, courtier en assurance for insurance, and carte de transactions immobilières for real estate. Partnerships with major international banks give clients access to selective vehicles typically reserved for institutional allocators. For families seeking an alternative to private banking without sacrificing product range, Alias offers a rare combination.
Laplace Nantes
Laplace targets client profiles that most local offices overlook: business owners (dirigeants) navigating company sales, French expatriates with cross-border patrimony needs, and sports professionals requiring tailored wealth preservation. The family office tier requires a minimum of €10M in managed assets.
As part of the national Maison Laplace network (formerly Expert & Finance), the Nantes bureau connects clients to a broader ecosystem. This includes private equity access, financial and real estate placements, and social counsel for entreprise leaders. Families facing liquidity events from company sales will find Laplace's dirigeant-focused model well suited to their needs.
ACF (Atlantique Conseil et Finance)
ACF is the only Nantes office deploying venture capital into early-stage tech startups. The firm invests €30K to €150K per ticket at pre-seed, seed, and Serie A stages. Its portfolio includes nine named companies: Firmly, GDevelop, Captain Cause, Benefiz, Noleo, Cosmo Connected, Alegria.tech, Koliving, and Artpoint.
Tech founders raising their first institutional round will find ACF uniquely positioned, combining family office resources with venture conviction. ACF also offers co-investment opportunities alongside its founding families. The portfolio skews toward consumer tech, social impact, and connected devices, though the office invests in all sectors.
Rezult
Rezult fills a coordination gap that most offices miss: it unifies a family's existing advisors under single-point oversight. With over €100M in advised assets and 50+ client families, the firm has built a confidential, long-term practice over more than a decade. Rezult focuses on dirigeants, high-net-worth (HNW) families, and entrepreneurs in transmission or exit phases.
Rather than managing assets directly, Rezult structures the relationship between clients and their network of lawyers, accountants, bankers, and notaries. For families who already have professional advisors but lack a central point of control, Rezult fills the family governance gap with juridical structuring, fiscal planning, and patrimony counsel.
Fastea Capital
Fastea Capital targets a niche no other local office covers: direct private debt and capital development for mid-market companies in the Grand Ouest. Its deals range from €700K to €6M, including a €2.5M private debt facility for a food industry company and a €1.5M capital allocation in patrimony renovation.
The 15-person team combines asset management with a dedicated wealth advisory division. This makes Fastea the natural partner for business-owning families who want their office to also finance regional companies they understand and can monitor closely.
Cyrus Herez Nantes
The Nantes bureau of Cyrus Herez brings institutional-grade gestion de fortune from a national network with 36 years of track record. The firm positions itself at the intersection of private wealth advisory and dedicated family services. For families seeking a provider with national scale, established compliance systems, and deep market access, Cyrus Herez offers a credibility profile that smaller boutique offices cannot match.
Investment Trends Shaping the Nantes Market
Private Equity and Private Debt Expansion
Fastea Capital's active deal pipeline (€700K to €6M per transaction) reflects a broader shift among Nantes wealth firms toward non-coté allocations. Multiple offices, including Alias Finance and Laplace, now offer private equity access as a core service. Private debt for regional SMEs in the food, industrial, and real estate sectors has become a preferred yield source for Grand Ouest families seeking alternatives to traditional financial markets.
Tech Startup and Venture Allocations
ACF's portfolio of nine tech startups makes Nantes an unlikely but genuine node for family-office-backed venture capital. Ticket sizes of €30K to €150K target pre-seed and seed rounds, filling a gap that institutional VC funds often ignore. Xelis also deploys capital into innovative enterprises, though with a broader mandate.
The Nantes tech ecosystem, anchored by incubators and a growing pool of digital talent, feeds this pipeline. More specifically, families with entrepreneurial backgrounds are driving demand for direct investment and co-investment access alongside their advisory mandates.
National Players Moving West
Rothschild Martin Maurel's decision to open a dedicated wealth office in Nantes signals that the Grand Ouest has reached a critical mass of wealthy families. Laplace's consolidation of Primonial Gestion Privée Nantes and OPTI Finance Nantes further concentrates national advisory power in the city. For local families, this expansion means more options. For independent MFOs, it means sharper competition from brand-name entrants.
Real Estate as Core Allocation
Real estate remains the default asset class for Nantes wealth holders. Cabinet Moison specializes entirely in real estate patrimony (technical, legal, fiscal, and rental management). Alias Finance holds a carte de transactions immobilières, and Nouvelle Donne Patrimoine recommends SCPI and direct property vehicles as long-term holdings.
Assurance-vie contracts backed by SCPI units offer a tax-efficient wrapper that most Nantes offices integrate into their patrimony strategies. Families with €10M+ portfolios typically hold 30% to 50% of their patrimoine in property-linked instruments.
How to Evaluate a Wealth Firm in This Market
Start with regulatory status. Any Nantes office providing investment advisory must hold CIF registration with ORIAS and the AMF. The public ORIAS registry allows instant verification. Offices operating under the French model without CIF status may offer patrimony coordination but cannot legally recommend specific products.
Independence determines advice quality. Épitome Finance and Alias Finance emphasize total independence from banking networks, meaning their recommendations carry no product commissions. In contrast, Rothschild Martin Maurel and other bank-affiliated firms operate within larger groups. Neither model is inherently better, but families should understand whether their office earns revenue from clients or from product providers.
Client count is a telling metric in this market. Épitome serves 10 families; Rezult serves 50+. Offices deliberately limiting their client base can dedicate more time per family. In practice, a Nantes office with a team of 6 to 8 people serving 100+ clients likely cannot deliver true depth of service. Ask directly how many families the office serves and compare that figure to team size.
Consolidated reporting separates genuine private wealth offices from rebranded CGP practices. Xelis offers self-hosted monthly reports covering financial, legal, and tax dimensions. Épitome provides monthly consolidated dashboards with secure web access. If an office cannot produce a single view of your entire patrimoine (portfolio holdings, insurance, real estate, tax positions), it is operating as a CGP, not a true family office.
Which Office Fits Your Needs?
UHNW families managing €100M or more in total patrimoine should focus on Épitome Finance's 10-family selectivity or Xelis Family Office's dual Nantes-Paris presence with full reporting. Both offer the depth of engagement and breadth of services that complex, multi-entity estates require. Families who want their office to also coordinate legal counsel, notaries, and bankers will find Épitome's general secretariat function hard to match.
Business owners preparing for a company sale or generational transition should consider Laplace Nantes. The firm explicitly serves dirigeants with patrimony structuring around liquidity events. That said, Rezult also specializes in entrepreneurs in transmission or cession phases, with a coordination model that integrates existing advisors rather than replacing them. Nouvelle Donne Patrimoine adds value for families with complex dynamics, including blended families, through its mediation-focused approach to estate planning.
Entrepreneurs seeking co-investment in startups have one clear option: ACF, deploying venture tickets into tech companies at pre-seed through Serie A. Families with strong real estate holdings should evaluate Cabinet Moison for dedicated property management or Alias Finance for combined financial and real estate advisory. French expatriates with cross-border needs can turn to Laplace, which explicitly serves this client segment with adapted patrimony counsel.
