# Ares & Co Ares & Co is a Consulting / Advisory based in Paris, France. ## Overview - **Organization type:** Consulting / Advisory - **Headquarters:** Paris, France - **Region:** Europe - **Address:** Paris, France - **Founded:** 2009 - **Assets under management:** Undisclosed - **Website:** aresandco.com - **LinkedIn:** https://linkedin.com/company/ares-&-co ## About Founded in 2009, Ares & Co was built by an unnamed collective of consulting and financial-services specialists as an independent advisory practice serving the C-suites of French and European financial institutions. The firm’s Paris office at 15 avenue de la Grande Armée houses teams that focus exclusively on general-management mandates across retail banking, corporate and investment banking, insurance, and investment funds. Its client base spans mutual insurers, bancassurers, development banks, and consumer-finance platforms. The partnership delivers a rare combination of strategic and functional expertise in five interconnected practices. Strategic planning and business-model redesign sit alongside advanced-analytics work covering ALM modeling, risk analytics, and customer-value segmentation. Finance-and-risk engagements include performance management, regulatory compliance, and balance-sheet optimization. A digital-acceleration practice rebuilds customer journeys, distribution architecture, and IT operating models, while an operational-excellence group handles post-merger integration, cost restructuring, and large-program assurance. The M&A practice executes acquisition due diligence, divestiture support, and securitization mandates. The firm does not manage third-party capital — it sells intellectual capital to general managements, not investment products. Team scale is undisclosed. In May 2026, Ares & Co announced the arrival of Ithier de Reilhac as a Partner in its Paris office, signaling a senior-level expansion (per the firm, May 2026). The partnership model mirrors that of professional-services firms: a lean senior roster deploying small expert teams against C-suite problems. The firm maintains a corporate social responsibility charter dating to 2017 and publishes thought leadership on topics such as European Central Bank rate-policy effects on banking margins. Ares & Co’s structural differentiator is its pure general-management mandate inside the financial-services vertical — it does not audit, does not implement software, and does not manage funds. That constraint positions the partnership as a neutral decision-support layer between a board and its operating committees, a niche that larger multi-service consultancies rarely hold without conflict. The firm’s governance remains opaque: no founding partners are publicly named, and ownership is not disclosed, which makes succession and equity architecture a key question for long-running client relationships. ## Sectors - Financial Services - Private Banking & Wealth Management - Consulting ## People - Ithier de Reilhac — Partner ## Questions ### What specific services does Ares & Co provide to financial institutions? Ares & Co organizes its work into six functional practices: corporate and business-unit strategy, advanced analytics (ALM, risk, pricing, customer value), finance and risk (performance management, regulatory compliance, balance-sheet optimization), digital acceleration (customer journeys, distribution, IT transformation), operational excellence (post-merger integration, cost optimization, program assurance), and M&A (due diligence, restructuring, securitization). All mandates are delivered directly to the general management of banks, insurers, and investment funds. ### Does Ares & Co manage third-party capital or investment funds? No. Ares & Co is a pure management consultancy. It does not manage pooled investment vehicles, does not offer asset management services, and does not deploy its own balance sheet as principal. The firm sells advisory and analytical services to the C-suites of financial institutions, not investment products. ### Which subsectors of financial services does the firm cover? The firm lists retail banking, corporate and investment banking, development banking, consumer finance, generalist insurers, mutual insurers, pension institutions, large brokers, private equity, and fintech/insurtech platforms as its client footprint. That breadth spans balance-sheet lenders, capital-light intermediaries, and regulated institutional investors. ### How does Ares & Co differentiate itself from large generalist consultancies? The firm operates exclusively for general managements of financial-services companies, avoiding audit, technology implementation, and fund management — activities that create conflicts inside multi-service firms. By remaining a pure advisory collective focused on a single vertical, Ares & Co positions itself as a neutral strategic layer between boards and operating committees, though this narrow focus also concentrates its revenue risk on the financial-services cycle. ## Related profiles - [Arconic Retirement Plans Master Trust](https://altss.com/profile/arconic-retirement-plans-master-trust) - [Argenta Wealth Management](https://altss.com/profile/argenta-wealth-management) --- Last updated: 2026-07-06T00:30:57.099Z Canonical page: https://altss.com/profile/ares-co Maintained by Altss — https://altss.com — methodology: https://altss.com/methodology
