MessageFlow SaaS · CPaaS
Key Result
Platform live in 8 weeks
Built and launched a multi-tenant CPaaS platform with messaging APIs, SIP trunking, billing, and a white-label reseller portal — from zero to first enterprise customer in 8 weeks.
MessageFlow had a narrow market window to launch a CPaaS product competing with established players. They needed REST APIs, carrier interconnect, real-time billing, and a reseller portal — not a 12-month build. CloudUCaaS deployed a production-ready platform using the same architectural patterns behind SignalMash.com, including US telecom tax calculation and multi-tenant rating.

MessageFlow needed to launch a multi-tenant CPaaS product with SMS and voice APIs, SIP trunking, usage-based billing, and a white-label reseller portal — all within an 8-week investor deadline. No existing infrastructure, no carrier contracts integrated, and no engineering team with telecom depth.
CloudUCaaS delivered a complete CPaaS stack: REST and SMPP APIs, carrier interconnect with failover routing, real-time CDR rating, Stripe billing integration, US telecom tax engine, developer sandbox, and a reseller admin portal. We used a modular microservices architecture on AWS EKS with CI/CD pipelines for weekly releases.
Platform went live on week 8 with first enterprise customers onboarded within 2 weeks. MessageFlow processed 2M API calls in month one and signed three reseller partners by month three, validating product-market fit ahead of Series A.
“We went from slide deck to production CPaaS in two months. CloudUCaaS brought the telecom expertise we couldn't hire fast enough.
