What Altius does
Altius is an independent full-service Belgian law firm headquartered at Tour & Taxis (Royal Depot, Havenlaan 86C, Brussels), founded in 2002 and operating as ALTIUS BV (Belgian company number 0476.389.071). The firm delivers legal advisory services across 16 practice areas — including Banking & Finance, Corporate and M&A, Dispute Resolution, Employment, ICT, Intellectual Property, Life Sciences, Private Equity, Public Law & Public Procurement, Real Estate Construction & Environment, and Regulatory — and structures its offering around a dual model of practice-area expertise and 13 dedicated industry teams covering Agriculture, Automotive & Mobility, Defence, Digital & Technology, Energy & Utilities, Pharmaceutical & Healthcare, Retail & Consumer Goods, and others. It serves corporate clients, SMEs, and international organizations requiring Belgian and EU legal counsel, with multilingual capability in Dutch, French, and English. The firm reports a 90-plus team of lawyers and specialists (firmographic headcount 101–250), and management includes Partner Carmen Verdonck and General Manager Bart Willems.
The firm's commercial model is professional services hourly billing, with rates varying by attorney seniority, specialization, and professional level, plus automatic annual increases from July 1st and a 10% late-payment administrative fee. Go-to-market is sales-led and direct: clients are acquired and served through the Brussels office via consultations, ongoing legal representation, and content marketing (corporate website, LinkedIn, X, Facebook, Instagram, email newsletter, and a "Stay Tuned" subscription). Beyond advisory services, Altius operates a small proprietary legal-tech product, ALTIUS PREAVIZ — a web and mobile application that calculates notice periods and severance indemnities in dismissal scenarios, available at preaviz.altius.com.
Strategically, the firm has emphasized organic expansion of its industry verticals (notably adding Defence), ongoing lateral hiring across 2025–2026, and external positioning through thought leadership on EU regulatory developments (e.g., the mandatory "Withdraw Here" button for EU webshops). In October 2025, the firm announced a multiyear exclusive partnership with Syd Life AI valued at $1 billion to support the US launch of preventive health and life-quality technologies — a move that, if accurately characterized, would represent a significant cross-border strategic step well beyond a typical Belgian mid-market law firm. Revenue is not publicly disclosed; no funding rounds, M&A activity, or external ownership (PE/VC) have been identified.
