Jebsen & Co.

What Jebsen & Co. does

Jebsen & Co. is a Buenos Aires-headquartered professional services 'boutique' founded on March 1, 1971 by Martín G. E. Jebsen, delivering an integrated suite of audit, tax advisory, legal, legal-tributary (tax disputes, transfer pricing, double-taxation treaties), and business process outsourcing services to foreign investors in Latin America and Argentine companies expanding internationally. The firm operates as a single-tier partnership under the name MGI Jebsen & Co. and is an Argentine member of the global MGI Worldwide accounting network (since 1988), which has roughly 10,000 professionals across ~460 locations in nearly 100 countries; MGI Worldwide's admission to the Forum of Firms took effect on January 1, 2019, and the MGI-CPAAI global merger on January 1, 2020 expanded the firm's international footprint.

Service delivery is grounded in an interdisciplinary team composed of CPAs, corporate lawyers, MBA-trained advisors, HR specialists, IT engineers, and public translators, organized into five core service lines (Auditing, Tax, Legal-Tax, Legal, Outsourcing) under dedicated partners and directors. The firm operates with multilingual capabilities (Spanish, English, German) to serve its international client base, currently distributed as approximately 47% European, 22% Argentine, 14% United States, 12% Asian, and 5% other Latin American clients. Pricing is bespoke and not publicly disclosed; client engagement is direct, with each client assigned a dedicated partner or manager, and there are no third-party resellers or intermediaries.

The firm is privately held with no parent company, no institutional funding rounds, and no public listing; ownership and management reside with a stable partner group that includes the founder (Martín G. E. Jebsen) and long-tenured partners such as A. Rafael Faillace (since 1986), Luis M. Uncal (since 1990), and Silvio J. Ureta (Audit Partner since 1995). Operating geographies include South America (primary), Europe, North America, Asia, and the broader Latin American region. Marketing channels are predominantly relationship-driven: LinkedIn, Instagram, and Twitter presence; webinars on tax and regulatory topics such as the Asset Regularization Regime; and newsletters and bulletins disseminated through direct client and network channels. The firm has no public products, APIs, patents, AI/ML capabilities, or proprietary technology platform beyond standard professional-services tooling.
