Fractional CTO: Scaling a SaaS Startup from MVP to Series A

The Challenge

An early-stage SaaS startup had built a promising MVP but was struggling to scale. The founding team had strong domain expertise but limited technical leadership experience. They were facing performance issues at 1,000 concurrent users, had no CI/CD pipeline, accumulating technical debt was slowing feature velocity, and they needed to demonstrate engineering maturity to potential Series A investors.

Our Approach

1. 1

   Audited the existing codebase and infrastructure, creating a prioritized technical debt remediation plan aligned with business milestones.

2. 2

   Re-architected the backend from a monolithic Node.js application to a microservices architecture with proper service boundaries and API contracts.

3. 3

   Implemented a comprehensive CI/CD pipeline with automated testing, staging environments, and blue-green deployments.

4. 4

   Hired and onboarded 4 engineers, establishing engineering culture with code reviews, architecture decision records (ADRs), and sprint ceremonies.

5. 5

   Built investor-ready technical documentation including architecture diagrams, scalability projections, and a technology roadmap aligned with the business plan.

Results

“Ryan was exactly what we needed -- someone who could think strategically about our technology while also rolling up his sleeves and shipping code. He was instrumental in our Series A success.”
