Active Network

Active Network (acquired by the massive Global Payments empire) is an absolutely massive, heavily armored veteran leviathan that mathematically defined the "Municipal and Global Event" market. It doesn't just run a soccer league; it engineered a highly secure, massive scale engine. It is the absolute weapon of choice for massive city Parks & Recreation departments who mathematically demand to process 10,000 summer camp registrations and adult softball leagues simultaneously on a single, unified financial ledger.
