Socios

What Socios does

Socios (legal name Socios Financieros, S.A., CIF A78981800) is a privately held, independent corporate finance advisory firm headquartered at Paseo de la Castellana 31, Madrid. Founded in 1991 by Nicholas Walker, Teodoro Millán, and Bosco Salaverri alongside executives from Benito y Monjardín, the firm advises on mergers and acquisitions, corporate restructuring, and strategic financial transactions for multinationals, large domestic corporations, private equity firms, and Spanish family companies. Stated mandate coverage spans sale transactions with Enterprise Values from €10 million up to €1 billion, plus global deal work alongside international PE groups.

The firm operates as a pure-play professional services partnership: it has no proprietary technology product, no disclosed revenue, and generates fee income from project-based advisory mandates rather than recurring contracts. It has no parent company, no subsidiaries, and no funding rounds — operating as a partner-owned firm that has been profitable on a self-sustaining basis for over 30 years. The current team comprises 8 partners supported by up to 15 directors, managers, analysts, and support staff (20+ professionals in total), with partner pedigrees spanning Citicorp, Bank of America, Merrill Lynch, Deutsche Bank, HSBC, Natwest Markets, Hawkpoint, Ernst & Young Corporate Finance, ABN AMRO, Calyon, Westdeutsche Landesbank, Deloitte, and Inveravante. Since inception, the firm has completed more than 350 transactions.

The firm's strategic distribution asset is its long-standing membership in Oaklins, a global alliance of independent investment banking firms with 850+ advisory professionals across 45 countries. Oaklins was ranked #2 globally by deal volume in mid-market M&A (deals up to US$500 million) in 2020 per Mergermarket data, positioning SOCIOS to compete on cross-border mandates against bulge-bracket and Big Four advisory groups despite its boutique scale. Go-to-market is sales-led and partner-driven, leveraging personal relationships, Oaklins network referrals, and a B2B professional services brand reinforced by partner contributions to industry publications and conferences. The firm completed a generational handover in 2021 (Walker to Emeritus, Millán retired, Dessioux elevated) and continued succession planning with Santiago Prieto's 2024 partner promotion.
