AB4 Systems Reviews
Have a look at these client reviews on previously delivered projects.
Jia Hui Tan
VP of Engineering - RedDot Technologies Pte LtdDelivered what the proposal described. More rare than it should be.
I have been through several technology implementations in my career. The pattern I am used to is: detailed proposal, optimistic timeline, scope creep, overrun, excuses at the end. This engagement broke that pattern at every stage. The timeline was realistic from the start. Changes were managed through process. The final delivery matched what was agreed. Simple, but uncommon.
Project summary
A regulatory change required us to rearchitect how we stored and processed customer call data. The timeline was set externally, not by our roadmap preferences.
Beatriz Cavalcanti
Chief Digital Officer - Cerrado Tech SASEO foundation they built is still generating organic traffic eighteen months later
Looking back, what strikes me most is how little drama there was. Real technology projects have problems. This one had them too — but every problem was flagged before it became a crisis, every scope change was handled through a proper process, and every risk was managed rather than buried. Our project manager said it was the smoothest vendor engagement he had been involved in. Given how complex the technical requirements were, I think that reflects genuine delivery maturity.
Project summary
Traceability legislation had set a compliance deadline that was not negotiable. Our supply chain system needed targeted development and we needed people who had done it before.
Thabo Ndlovu
Head of Technology - Highveld Tech Pty LtdAI in production within 8 weeks. The board saw it working before they approved the next phase.
We have worked with a few agencies over the years and the comparison is honestly not close. What stood out from the start was that they spent serious time understanding the problem before they proposed anything. Once development started, every sprint review was clean — no hidden surprises, no slipped milestones. The production system has been running for four months without a single critical issue. Our internal developers reviewed the codebase at handover and were genuinely complimentary about the quality. That does not happen often.
Project summary
First notice of loss was averaging three days. The market benchmark was under four hours. Automating intake and triage was the agreed priority for the year.
Adriana Voss
Director of Platform Engineering - Cascadia Digital VenturesThe outcome we needed, on the timeline we needed it, by people we would use again
The platform has been live for six months and is handling three times the transaction volume we scoped for. That is not because we underestimated — it is because the architecture choices made during discovery were genuinely forward-thinking. Most vendors design for exactly what you tell them. This team designed for what you are likely to need. We are already scoping the next phase and there was no question about who we would use.
Project summary
Our connected vehicle platform was accumulating telemetry data from a growing EV fleet with no clean way to act on it. We needed both the infrastructure and the analytics layer.
Rupert Ashford
Director of eCommerce - Hargrove Retail PLCMixed reality experience that impressed the client audience we were trying to win
The part of this project I had been most worried about was the integration work. Our system landscape is complex, some of the upstream APIs were barely documented, and one of our third-party vendors was notoriously slow to respond. This team documented what the upstream vendors could not, built resilience into the architecture where third-party reliability was uncertain, and delivered integrations that have worked exactly as specified since day one. I genuinely could not have asked for more.
Project summary
Moving to a direct-to-consumer model required a platform capability we had never needed before. The build needed to be right the first time given the marketing spend committed to the launch.
