Success Story

Series B SaaS platform seeking enterprise customers and partnerships

Challenge

Existing internal API inconsistent and poorly documented. Enterprise prospects demanding API access. Partnership opportunities requiring integrations. Current API couldn't handle external use - security gaps, no rate limiting, breaking changes common.

Solution

Fractional CTO led complete API redesign. Implemented REST API with consistent patterns, OAuth2 authentication, comprehensive rate limiting, detailed OpenAPI documentation, and developer portal with sandbox. Created versioning strategy to prevent breaking changes.

Results

Closed 3 enterprise deals worth $800,000 ARR requiring API access. Launched 5 partnerships with major platforms. Developer portal attracted 200+ external developers. API became product differentiator in sales. Zero security incidents.

Timeline: 10 weeks from design to production launch
