Case Study: a leading telecommunications company scales a SaaS platform with Belitsoft

Custom SAAS Web Application for the International Calling Company

Belitsoft worked with a leading telecommunications company, a global fintech and communications business in the USA, to launch and scale a new prepaid international calling, mobile top-up, and money transfer SaaS app for immigrant and diaspora communities. The client needed to move fast, build from scratch, and overcome a shortage of in-house senior .NET, Azure, and Angular talent to beat competitors to market.

Belitsoft provided a dedicated team with .NET, Azure, Angular, QA, and UX/UI specialists, supported by Agile delivery, cost-plus pricing, and QA automation. The result was a scalable, high-performing SaaS platform that reached more than 7 million users with no performance issues, expanded to nearly 20 specialists within six months and later 25 full-time team members, and reduced testing costs by about 30%.
