What SENDO does

SENDO is an omnichannel customer engagement platform that unifies messaging, voice, AI agents, and network APIs on carrier-grade infrastructure. Its product suite spans SMS, WhatsApp, RCS, push notifications, cloud numbering in 90+ countries, voice termination, network APIs for verification and number intelligence, and AI-powered conversational agents built on parent group BTS Group's proprietary TALKINGbits technology. The underlying architecture is event-driven, processing 3.5B+ API requests annually through a load-balanced gateway feeding dedicated channel services and carrier-grade connectors with no single point of failure, supporting a 99% uptime SLA across points of presence in Miami, Madrid, Paris, Singapore, and Tokyo.

The platform serves financial institutions, enterprises, telecom operators, BPOs/contact centers, and growing businesses. Revenue is generated through three streams: usage-based pricing on messaging, voice, and API consumption with no platform fees; custom enterprise contracts with SLAs and 24/7 support; and white-label platform licensing for telecom operators and resellers. Go-to-market combines enterprise field sales with custom migration planning, inside sales with self-serve onboarding, and an API-first developer motion supported by sandbox keys and comprehensive documentation. Notable enterprise customers include Diners Club Ecuador, for which Sendo migrated 20 million monthly SMS messages within minutes with zero customer-facing disruption, and American Call Center (ACC), Ecuador's leading contact center.

SENDO operates as a subsidiary of BTS Group, a strategic investor in advanced communications technology headquartered in Miami, which provides the carrier interconnections, global infrastructure, and proprietary AI technology underpinning the platform. Founded in 2023 and officially launched in 2024, the company is privately held with 6 employees and no disclosed external funding rounds.
