What Ploum does

Ploum is an independent, full-service law firm and notarial practice headquartered in Rotterdam, Netherlands, founded in 1995 by seven partners including Rutger Ploum. The firm employs over 100 lawyers and notaries organized across more than 30 practice areas spanning employment law, corporate/M&A, intellectual property, customs and trade, energy, environmental and planning, insurance, transport and shipping, food and feed regulatory, construction, IT, privacy, and litigation, as well as integrated notarial services.

Its core offering is multidisciplinary legal counsel delivered through partner-led client engagements, with recognized sector specializations in energy transition, transport and logistics (anchored by Rotterdam's port), food and consumer products, and technology/media/telecom. Ploum maintains top-tier analyst rankings across Chambers Europe 2026 and Legal 500 EMEA 2026, including Band 2 in Corporate/M&A and Tier 1 in both Food and Transport, and is a founding member of the Greenlane international customs and trade law network and a member of the Food Lawyers Network, giving it cross-border reach without proportionate fixed cost.

The firm generates revenue through professional services billing, primarily hourly rates, retainers, and matter-based fees that are not publicly disclosed. Its go-to-market is enterprise field sales supported by thought leadership content, legal newsletters, sector-focused events (Ploum Academy), and third-party directory validation. The customer base spans large multinationals (Ford, Harley-Davidson, Coty, Arla Foods, Donna Karan), mid-sized Dutch companies, and select startups in regulated verticals, with no disclosed revenue concentration or external equity ownership — the firm operates as a partner-owned partnership under the traditional Dutch model.
