The story
Jonas Club Software is a vertical SaaS provider for private clubs (golf, country, city clubs) operating for 35+ years and serving ~2,300 clubs in 20+ countries. Owned by Constellation Software (Canadian serial-acquirer of vertical software). Historically an on-premise club management, POS, and back-office platform, it has been layering embedded finance in recent years — most notably Jonas Payments, CSI Pay (embedded AP with rebate revenue), and Stripe-powered mobile POS card acceptance — moving toward being the financial system of record for clubs.
