What Sirius Legal does

Sirius Legal (legal entity: Sirius Legal Business Law Firm BV) is a privately held Belgian boutique law firm founded in 2010 by Managing Partner Bart Van den Brande, headquartered in Mechelen with a second office in Hasselt. The firm specializes in digital-economy law, with practice areas spanning IT/IP, privacy and data protection (GDPR), e-commerce, media and advertising, intellectual property, consumer and market practices, contracts, gambling law, and travel law. Its stated differentiator is a hybrid team combining qualified lawyers with experts recruited from media and IT backgrounds, intended to deliver practical, business-aware advice to digital and technology-oriented clients.

The firm operates a dual revenue model. The primary stream is traditional hourly legal advisory billed at partner-tier rates of €180–€250/hour (partners €220–€250, senior lawyers €200–€240, junior lawyers €180–€200, excluding VAT), with 30% retainers required before work commences and third-party costs passed through transparently. The secondary stream is a productized e-commerce webshop selling fixed-price standardized legal products aimed at Belgian B2B clients (GDPR Audit €3,500, GDPR Helpdesk €3,500, Cookiescan legal-and-technology bundle €3,000, Website Certifier €1,500, Privacy Policy €750, AI Policy €750, Whistleblower Policy €750, Data Export DTIA €1,500, Company Privacy Policy from €750, Dataregister + Advice €500, DPO-as-a-Service).

The webshop is supported by a content-marketing engine including the Sirius Blogt blog, the Sirius Talks webinar series (hosted on YouTube and distributed via Zoom, Google Meet, Livestorm, and Microsoft Teams), LinkedIn and Facebook presence, a newsletter, and a careers page indicating regular hiring. Sirius Legal is integrated with Koalendar for meeting scheduling, MultiMinds as a technical implementation partner for cookie compliance, and an AI-powered meeting-notes tool used during client consultations. The firm maintains disclosed enterprise clients including Dela, Keytrade Bank, Mazda Belgium, Samsung Belgium, STIHL Belgium, DMLights, Antwerp Management School, and Wunderman Thompson Antwerp. Its gambling team has contributed the Belgian law chapter to the International Comparative Legal Guide to Gambling for six consecutive years.
