Executive Summary

Many companies that rely on SMS OTPs and verification—fintechs, marketplaces, identity providers and large SaaS onboarding flows—face frequent delivery failures caused by carrier fragmentation, anti-spam filtering and fragile single-provider setups, which leads to lost conversions and compliance risks. This pain is acute for businesses scaling globally where local carrier behavior and filtering rules vary by region. You could build a vendor-agnostic orchestration layer that provides multi-provider connectivity, intelligent routing and automated failover, real-time deliverability analytics, cost-aware routing rules and developer-friendly APIs/SDKs to swap providers or route around failures without changing application logic. The product would package SLAs, monitoring and programmable policies so reliability becomes a platform feature rather than manual ops work. The market is sizable and timely—approximately a $6.0B opportunity (2M businesses × ~$3K ACV) with strong tailwinds from digital-first onboarding and mounting anti-spam complexity (market score 84/100, revenue potential 85/100). Competition is medium, but growing vendor lock-in and the operational pain of managing many carriers creates demand for a neutral orchestration layer. You can differentiate through deep provider diversity, dynamic ML-driven routing, transparent deliverability metrics and a developer-first UX, but be upfront: success requires building a broad provider network, strong regional compliance and a few anchor customers to prove deliverability and justify the switch.
