What Ismail Sabri Wee & Wong (ISW Legal) does

Ismail Sabri Wee & Wong, trading as ISW Legal (legal entity: IJsseldijk, Smit & Wouters / ISW Legal IP), is a Dutch law firm founded in 1985 by Daan IJsseldijk in Amsterdam and Rotterdam. Originally established as a general practice covering banking, real estate, family, wills, trust and succession law, the firm expanded into Intellectual Property and Corporate & Commercial work in 2000 and rebranded to ISW Legal IP in 2013 in close association with ISW Europe Legal IP. The firm operates from two Netherlands offices and is registered before the BOIP, EUIPO and EPO as a European Patent, Trademark and Industrial Design Attorney, and is a member of the Nederlandse Orde van Advocaten and a WIPO partner.

The firm's core product surface combines traditional professional-services engagement with a content-led growth engine in the form of GDPR.guide — a plain-English online resource covering all 99 GDPR articles, 173 recitals, FAQs, glossary entries, legislative process, timeline and ongoing enforcement updates. This resource functions as both an authority-building content asset and a top-of-funnel client acquisition channel for the firm's data-protection practice. Alongside GDPR/data-protection advisory (audits, DPO support, international transfers, breach response), ISW Legal offers IP and IT legal services, banking and real estate transactions, and corporate/commercial counsel. The disclosed team comprises Managing Partner Daan IJsseldijk, Partner Sanne Smit, Legal Associate Lars Wouters and Corporate Department associate Eva de Vries, with no public headcount total.

Revenue mechanics are traditional professional-services billing: quote-based engagements priced per matter, with no disclosed pricing tiers, retainers, or subscription products. Customer segments are horizontal — any organisation processing EU personal data for GDPR work, IP owners seeking registration, businesses in transactional banking/real-estate matters, and corporate clients needing deal support. Distribution is direct via consultation requests ([email protected] / +31 (0)20 240 1985), supplemented by the GDPR.guide organic content funnel and a blog/insights feed. Revenue, deal volume and detailed headcount are not publicly disclosed.

Scale indicators2 records

Recent moves6 records

Expansion highlights4 records

Emerging players

• DataGuidance (OneTrust DataGuidance): Subscription research platform providing country-by-country privacy and data protection regulatory tracking. Comparable to ISW Legal as a content-led GDPR resource targeting the same privacy professional audience, but with broader geographic coverage and a paid SaaS model rather than a law practice.
• OneTrust: Privacy, security and governance technology platform offering DPO tooling, consent management and compliance automation. Comparable to ISW Legal as an alternative route for GDPR compliance work, addressing the same buyer pain points but through software rather than legal counsel — relevant where the firm competes with platform-driven self-service.

Others

• IAPP (International Association of Privacy Professionals): Global privacy professional association and credentialing body publishing extensive GDPR resources and trainings. Comparable to ISW Legal as a competing authority and content resource for privacy practitioners, though it operates as an industry body rather than a law firm and is an ecosystem enabler rather than direct competitor.

Direct peers

• Novagraaf: European IP service provider with Benelux roots registered before EUIPO and EPO. Closely comparable to ISW Legal on the IP registration side of the practice (patents, trademarks, designs), with a similar technology-focused IP client base but broader European footprint.
• Kennedy Van der Laan: Amsterdam-based mid-sized firm widely recognized for its specialist privacy, data protection and technology law practice. Closely comparable to ISW Legal in niche focus, target client profile (Dutch and EU businesses needing GDPR support) and content-driven authority building, while operating at a slightly larger scale.
• Brinkhof: Amsterdam-based specialist IP and technology law firm registered before BOIP, EUIPO and EPO. Directly comparable to ISW Legal on patent, trademark and design prosecution before the same Benelux and European IP offices, serving similar tech and brand-owner clients.

Broad incumbents

• De Brauw Blackstone Westbroek: Premier Dutch law firm in Amsterdam with a top-tier technology, media and data practice. Comparable to ISW Legal on GDPR advisory and corporate transactions for large Dutch and multinational clients, but competes at the very top of the enterprise market.
• Bird & Bird (Netherlands): Major international law firm with a substantial Dutch practice and a globally leading tech, data protection and IP group. Comparable to ISW Legal through its overlap in GDPR compliance, data transfers and IP registration work for tech and life sciences clients, but operates at far greater scale and geographic reach.
• Houthoff: Leading Dutch full-service law firm headquartered in Amsterdam with a strong data protection, IP and corporate practice. Directly competes with ISW Legal for Dutch enterprise GDPR, IP and corporate mandates, but offers broader sector coverage and a much larger partner bench.
• Stibbe: Amsterdam-headquartered Benelux law firm with established data protection, IP and corporate practices. Comparable to ISW Legal on GDPR and IP advisory for Dutch corporates, but with substantially greater resources and international reach.
