Club Atlético de San Isidro

What Club Atlético de San Isidro does

Club Atlético de San Isidro (CASI) is a private membership-based sports club (asociación civil) founded in 1902/1903 and headquartered in San Isidro, Buenos Aires Province, Argentina. The club operates five facilities across the San Isidro and Tigre districts — the main headquarters on Roque Sáenz Peña 499, the La Boya sports complex (Campo Rafael Cullen), the La Playita nautical center, the Anexo Benavidez satellite, and the San Isidro Labrador 18-hole golf course — and serves approximately 7,000 members (socios). Its core product portfolio spans competitive and recreational rugby (the flagship discipline, with 33 URBA championships), women's hockey, tennis, football/soccer, plus a long tail of additional sports including bowls, bridge, Gaelic football, swimming, nautical sports (kite surf, SUP, kayak, sailing, foil), padel, paleta, squash, and golf, alongside adult fitness classes (Bootcamp, Funcional, Yoga, Pilates, Cardio Fitness, Caminata Seniors) and youth development programs (escuelitas for ages 3-12).

CASI's underlying technology is the Simple Solutions member management and booking platform, used for court reservations, QR-code access control, fee payments, guest registration, and class enrollment; the platform is deployed as a mobile app on iOS/Android and represents standard transactional SaaS rather than differentiated technology. The club has no disclosed AI/ML capabilities and does not expose an API or external integrations.

CASI's business model is hybrid subscription-plus-transactional. Members pay recurring monthly social quotas (adjusted for inflation under UTEDYC paritarias, with reported 4-6% monthly adjustments in 2024) and optional sport-specific subscription tiers such as Arancel Deportes (unlimited access to classes and court rentals). Transactional revenue streams include facility rentals (Salón Rafael Cullen, multiple quinchos, events), individual sport court bookings, golf green fees and driving range fees, guest day passes, and ancillary services (sauna, massages, billiards). Go-to-market is community-led: new members join through word-of-mouth referrals, family connections (children of members), escuelitas enrollment, and reciprocity agreements with four peer Argentine clubs (Club Atlético del Rosario, Sociedad Sportiva de Bahía Blanca, Club Atlético Estudiantes de Paraná, Córdoba Athletic) that capture relocating members. Pricing is publicly disclosed in Argentine Pesos and tiered between Socios (members) and No socios (non-members), with the member discount functioning as a core retention lever.
