What Nuso does
Nuso is a cloud communications service provider delivering voice, messaging, unified communications (UCaaS), contact center (CCaaS), and platform services to small and medium businesses, enterprises, and global service providers across 30+ countries, with footprint expanding to 40+ via its BICS partnership. The platform is built on a cloud-first, AI-enabled architecture featuring carrier-grade voice services across the US, Canada, UK, and EU, with redundancy provided through NUSOflex, an AI/ML-driven solution that monitors and reroutes around PSTN impairments at country, region, state, and city granularity. Core products span contact center (NUSO Connect for Business, NUSO Connect for Enterprise from T-Metrics, Attendant Console, Connect Recorder), unified communications (UCaaS, NUSO Bridge for Microsoft Teams, NUSO Bridge for Zoom, SIP Trunking, Operator Connect for Teams, Zoom Cloud Peering, NUSO Messaging, IPFax, Branded Calling ID), and platform services (Command & Control, NCCP, Global Service Provider Platform). Nuso operates a multi-modal distribution model combining direct enterprise field sales, an extensive channel partner ecosystem (UC resellers, MSPs, global service providers), and hyperscaler-embedded channels (Microsoft Operator Connect, Zoom App Marketplace, BCID/CTIA). Revenue is generated through recurring per-seat UCaaS subscriptions, usage-based SIP trunking and A2P messaging (per-minute/per-message), 15% recurring partner margin on Zoom Powered by NUSO, and platform/API services to wholesale carriers. The compliance footprint (HIPAA, GDPR, NIS2, MiFID II, ISO 27001/9001, FedRAMP Moderate, GovRAMP, JITC, CMMC L2/L3) and 200+ CRM integrations (Salesforce, HubSpot, Microsoft Dynamics, Autotask) are core to its go-to-market in regulated verticals and against single-vendor UCaaS stacks.
