Vital Team
Structuring the tech of an HR SaaS in production
Taking over the technical leadership of an HR SaaS in production
Context
Vital Team had built an HR SaaS with real product-market fit, but they lacked technical leadership: no CTO, technical debt accumulating, no clear roadmap, and the startup losing momentum on the product side.
Challenge: Take over as Fractional CTO with immediate need to audit the existing platform, understand the technical debt, establish a clear technical roadmap, and resume development. The challenge: do this while maintaining the live product and serving existing clients.
