Why this is a gap

Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.

The market

Nordic identity verification app users are experiencing a real but niche pain—app crashes during SMS confirmation flows—with 0 searches indicating this is a support issue, not a market trend.

Competition & the opening

Already owned an incumbent owns the exact job Moat 1/10 · no real moat Market 6/10 · a real vertical
Category giants · 9/10 vs Twilio Verify (with mobile SDK)Auth0 / Okta (SMS MFA + mobile SDK)AWS Cognito (SMS OTP + mobile libraries)Firebase Authentication (SMS + Android/iOS SDKs)Vonage Verify API (mobile SDK wrapper included)Telesign Authentication (mobile-optimized SMS flows)

Extremely crowded (9/10) with six major SDK providers (Twilio, Auth0, Okta, AWS, Firebase, Vonage) already solving SMS MFA at scale. A wrapper around these adds marginal value unless it fixes a very specific app-crash scenario that incumbents don't address.

What's hard to build

Mobile OS fragmentation (Android/iOS version compatibility) and the fact that Nordic apps use proprietary SDK integrations make it hard to build a generic wrapper. You'd need to reverse-engineer why apps crash on exit, which may be app-specific rather than a platform-level problem.

Why now

SMS OTP flows are table-stakes but mobile app SDK integration remains fragile across Android/iOS; a stability wrapper adds real value where Twilio and Auth0 SDKs still have gaps.
