What Antes does

Antes is a regional Dutch mental healthcare organization (GGZ) specializing in the integrated treatment of (severe) psychiatric conditions and addiction for adults, youth, and the elderly. Operating as a care brand under Parnassia Groep — the largest mental healthcare provider in the Netherlands — Antes treats approximately 30,000 clients annually across the Rotterdam-Rijnmond and Zuid-Holland-Zuid regions. Its service portfolio spans the full care continuum: a 24/7 crisisdienst, acute and open admissions (SEHP), high-intensive care (HIC), long-term closed treatment, dual-diagnosis (LooDDs) programs, FACT community teams, intensive home treatment (IBT), outpatient detox, protected living (Beschermd Wonen), specialized geriatric psychiatry, and the Youz Antes youth division. Physical infrastructure includes multiple clinics in Poortugaal, Rotterdam, Capelle aan den IJssel, Spijkenisse, and Tiengemeten, plus the newly opened Behandelcentrum Watermolen (98 beds, May 2026) and the planned Kliniek Rotterdam Alexander (200+ beds, 2027) co-located with major hospitals.

The business model is funded almost entirely through the Dutch basic health insurance system (zorgverzekering) under regulated GGZ tariffs and DBC financing, with additional flows from municipal social-domain budgets for protected living and youth care. Antes generates no app- or subscription-based product revenue; all offerings are reimbursed clinical services. Go-to-market is mixed: direct-to-consumer via self-referral and a centralized 24/7 crisis phone number, plus referral-based intake from general practitioners, hospitals, and the Parnassia Groep Verwijzerspunt. Marketing is non-commercial — primarily informational website content, social media (Facebook, LinkedIn, Instagram), news updates, and the 'Te gek werk' employer-branding podcast hosted by Splinter Chabot. Operationally, Antes holds ISO 27001 and NEN 7510 information-security certifications and complies with AVG/GDPR privacy regulation under a Parnassia-wide privacyreglement.

Strategic positioning is centered on three differentiators: (1) integrated dual treatment of addiction and psychiatry, (2) regional scale in a defined catchment area, and (3) institutional backing from Parnassia Groep, which provides shared services, legal entity infrastructure (PG Zorgholding BV), and network effects across sister brands including Indigo, Brijder, PsyQ, and Reakt. Revenue, profitability, and headcount detail beyond the 1,001–5,000 employee band are not publicly disclosed.
