What Clients Say

"

Working with R2SA transformed our deployment pipeline. We went from weekly releases to shipping to production multiple times a day, with confidence. The Kubernetes platform they built has been rock solid.

Sarah Chen
VP Engineering, FinTech Scale-up
"

As our Fractional CTO, R2SA helped us raise our Series A with a credible technology story. They built the team, chose the right stack, and delivered the technical roadmap investors needed to see.

James Okafor
Co-founder & CEO, B2B SaaS Startup
"

Our AWS bill was out of control. R2SA conducted a thorough architecture review, right-sized our infrastructure, and we saved £180k in the first year without any reduction in performance.

Rachel Thompson
CTO, E-commerce Platform
"

R2SA built our entire AI infrastructure from scratch — RAG pipeline, LLM gateway, evaluation framework. What would have taken our team six months was live in six weeks. The quality was exceptional.

David Park
Head of Product, AI-first SaaS
"

We brought R2SA in to rescue a failing platform migration. Within two weeks they had diagnosed the root causes, stabilised the system, and laid out a clear path forward. Exactly what we needed.

Engineering Director, Enterprise SaaS
"

The DevOps transformation R2SA led was the best investment we made last year. Our deployment frequency went from monthly to daily, incidents dropped by half, and the team confidence is through the roof.
