C2iS Reviews
Write a ReviewConnected hardware platform that eliminated the blind spots in our operational data
Flynn Buchanan / GM of Technology - Pacific Rim Commerce GroupMay 20, 2026
Project summary: Our engineering capacity was committed to maintaining existing systems and could not absorb a net-new build of this complexity. An external partner with the right skills was the only viable option.
The integration layer was the part of the project I was most concerned about going in. Our system landscape is complex, several of the upstream APIs we relied on were poorly documented, and two third-party vendors had a history of unpredictable response times on integration questions. This team managed all of that. They documented what the upstream vendors could not, built resilience into the integration architecture where the upstream behaviour was unreliable, and delivered a solution that works as specified in production. I could not have asked for more.
Delivery timeline that proved achievable rather than optimistic, estimation accuracy that reflected real analysis rather than competitive bidding, scope discipline that prevented the feature creep we had experienced before
Pipeline availability for kickoff required a few weeks of lead time — in hindsight that selection pressure means you are working with a team that is in demand for the right reasons
Questions & Answers
Delivered on scope, on time, and with code quality that passed our strictest review
Beatriz Cavalcanti / Chief Digital Officer - Cerrado Tech SAApr 14, 2026
Project summary: Several years of incremental development had left us with a platform that was technically functional but strategically limiting. A structured rebuild was the agreed path forward.
The technical quality of the final deliverable is the easiest thing to point to. The automated test coverage is thorough, the deployment pipeline is reliable, the documentation is genuinely useful rather than ceremonially produced. But the metric I keep returning to is the number of post-launch conversations we have not had to have. No incident calls at two in the morning. No emergency patches. No retrospective discussions about what went wrong. The absence of those events is the evidence I would show to someone considering this vendor.
Architectural decisions designed for longevity rather than just the current brief, thorough automated test coverage, post-launch stability that validated every technical choice made during discovery
Time zone coordination required some deliberate overlap management from both sides in the first couple of sprints, after which we had an efficient async rhythm that worked for the whole project

Project summary: We wanted a property listing platform with advanced search, virtual tours, and CRM integration.
The team demonstrated exceptional technical depth throughout every phase of the project. Communication was proactive and transparent — we always knew exactly where things stood. They challenged our assumptions constructively and suggested improvements that made the final product significantly better than our original spec. Delivery was on schedule, the code quality was outstanding, and post-launch support has been prompt and thorough. We could not have asked for a better partner.

Exceeded all expectations — highly recommended
William Brown / Senior Consultant - Brown ConsultingSep 26, 2023
Project summary: Our company needed a reliable technology partner to deliver a complex project within a tight timeline.
From the discovery workshop to the final handover, the experience was seamless. The team invested real effort in understanding our business goals before writing a single line of code, and that foundation paid dividends throughout. Every milestone was hit, every deliverable was polished, and the few issues that arose were resolved before we even had to ask. The solution has already delivered measurable ROI and we are planning our next engagement with them.
Deep technical expertise, professional project management, responsive support, great value
Slightly higher day rate than some alternatives, but the quality justifies every penny
