Ten Holter Noordam advocaten

What Ten Holter Noordam advocaten does

Ten Holter Noordam Advocaten (THNA) is a Rotterdam-based Dutch law firm operating as a private partnership. THNA delivers specialized legal advisory services through a team of 60+ named lawyers organized across 18 practice areas and four target vertical sectors: Bouw (Construction), Haven (Port/Maritime), Overheid (Government), and Zorg (Healthcare). The firm's service portfolio spans M&A, public procurement law, employment law, administrative and environmental law, contract law, litigation, insolvency, privacy, energy, transport/logistics, and several other specialized domains. Client engagement is direct, with lawyers delivering counsel on hourly, fixed-fee, or matter-based arrangements.

The firm operates without any proprietary technology platform — it is a people-and-expertise business, not a technology product company. THNA's commercial motion is enterprise field sales: direct client engagement with specialized lawyers, supported by content marketing (legal blog), monthly webinars on procurement-law jurisprudence, industry events such as the annual Havenborrel port networking reception, and an email newsletter. The firm's international reach is delivered through memberships in four referral networks (Mackrell, IAG Global, Nextlaw Network, and Netlaw) rather than through foreign offices. The firm is governed by a board of partners, with insolvency-law specialist Sjoerd Warringa having recently joined the board as part of a governance change.

THNA serves enterprise and mid-market clients, with named transactional/M&A engagements spanning VT Group, Centillion Solutions Netherlands, VORM, Dutch Industrial Safety Consultants, MSR Verhuur, McArt, and RBC Group. Recurring revenue is structured around professional-services billing (hourly rates, fixed fees, or matter-based arrangements), with no subscription, recurring SaaS, or productized revenue streams. The firm's primary sources of competitive advantage are the specialized talent bench, deep domain expertise in the four target verticals, and proximity to the Rotterdam port and construction economy. Revenue is not publicly disclosed and the firm has no parent company, no institutional investors, no funding rounds, and no M&A activity recorded in the input data.
