What Bonn Steichen & Partners does

Bonn Steichen & Partners (BSP) is an independent full-service law firm headquartered in Leudelange, Luxembourg, operating as a société en commandite simple (limited partnership) registered with the Luxembourg Bar under List V. Founded circa 2012–2013, the firm employs 51–100 staff including 17 named partners and a bench of counsels, senior associates, and junior associates. BSP delivers legal advisory services across 18 practice areas covering banking and financial services, capital markets, corporate and M&A, investment management, private equity, sustainable finance, tax, litigation and arbitration, insolvency and restructuring, employment and compensation, IP and data protection, real estate, private wealth, and AML compliance. The firm also maintains dedicated country desks for French, German, Italian, and Nordic clients (Danish, Swedish, Norwegian, Finnish), enabling multilingual service delivery in English, French, German, Italian, and Danish.

BSP operates a professional services revenue model, billing clients at hourly rates as specified in Engagement Letters, with fees calculated on time spent, complexity, urgency, risk, expertise required, and transaction value, plus a flat 5% administrative charge and optional success fees. The firm has no disclosed product or SaaS technology platform; its technology footprint is limited to AI tools used under lawyer supervision for research, document analysis, summarization, and drafting. Go-to-market is relationship-driven, combining industry rankings (Chambers, Legal 500, Leaders League, Best Lawyers), content marketing (newsletters, newsflashes, brochures, videos), event sponsorships (BSP Tax Forum, Nordic Roadshows, VAT Masterclasses), LinkedIn presence, email newsletters, and the international country desks themselves acting as targeted client acquisition channels. The firm is privately held by its partners, has no external institutional investment, no parent company, no subsidiaries, and no M&A activity.

Strategic positioning emphasizes full-service Luxembourg law capability for cross-border clients, evidenced by multiple 2024–2025 analyst rankings (Chambers Global 2025, Chambers Europe 2025, Legal 500 2024 top-tier, Leaders League 2024), co-marketing partnerships with Deloitte Luxembourg and RBC Investor & Treasury Services, pro bono participation, and a recent regulatory mandate in the Kaupthing Bank Luxembourg criminal case concluded on 22 October 2025. The firm operates from a single Luxembourg office and serves clients across Europe.
