CSG International

What CSG International does

CSG International is a global provider of cloud-native SaaS solutions for customer engagement, billing, payments, and monetization, serving approximately 900+ enterprise customers across telecommunications, financial services, healthcare, media, utilities, and government verticals in 85+ countries. Founded in 1987 and headquartered in Englewood, Colorado, the company operated publicly on NASDAQ (ticker: CSGS) until May 2026, when NEC Corporation completed an approximately $2.9 billion acquisition, integrating CSG with NEC's Netcracker Technology subsidiary under Chairman and CEO Andrew Feinberg.

The company's product portfolio centers on three core platforms — CSG Ascendon (cloud-native monetization supporting subscription, usage, prepaid, postpaid, hybrid, milestone, and evergreen billing models), CSG Xponent (customer journey analytics and orchestration with next-best-action recommendations across 150+ native integrations), and CSG Quote & Order (AI-powered CPQ and order management) — supplemented by CSG Payment Enablement, CSG EaaS (powered by subsidiary NetLync), CSG Assure for roaming, CSG Encompass for quote-to-cash, and CSG Deal Manager. The platform processes $175B+ in payments, 250M+ transactions, and 300B+ customer interactions annually. AI/ML capabilities include recommendation engines, predictive analytics for churn and fraud, NLP-based conversational AI, and process automation; the company holds ISO 42001:2023 AI management certification alongside ISO 27001, PCI DSS v4.0 Level 1, SOC 2 Type II, HIPAA, GDPR, and CSA Star Level 2.

Revenue is generated through three streams: SaaS/subscription contracts (primary), usage-based transaction and payment processing fees, and professional services for implementation and integration. The company sells primarily via direct enterprise field sales to C-suite and VP-level buyers on multi-year engagements, supplemented by channel partners — most notably NEC/Netcracker, which serves as a global deployment vehicle in telecom. Named enterprise customers include Comcast, Charter, Telstra, MTN, PLDT, JPMorgan Chase, Wells Fargo, Swedbank, MetLife, Memorial Health System, and AMC. FY2024 revenue was approximately $1.22 billion with EBITDA that doubled to roughly $347.9 million by acquisition close; organic revenue growth has been in the low single digits, supplemented by acquisitions including DGIT (2021), Tango Telecom (2021), Kitewheel (2021), and ICG Pay (2024).
