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.
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.
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.
