Nonstop Reviews
Have a look at these client reviews on previously delivered projects.
Ananya Sharma
Engineering Manager - BlueMind Analytics Pvt LtdThey understood the difference between AI that demos well and AI that runs in prod
We went with a smaller team than we had originally planned for. I had concerns about whether the capacity would be sufficient given our timeline. Those concerns were unfounded. The team was focused, communication was constant, and the quality at each milestone review was consistent throughout. Smaller does not mean slower when the people are the right ones and this engagement proved that.
Project summary
Smart meter rollout generated data volumes our analytics infrastructure could not handle. We needed a platform that scaled without requiring a rebuild every two years.
Rupert Ashford
Director of eCommerce - Hargrove Retail PLCProposal matched the outcome. That alignment is rarer than vendors acknowledge.
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
A failed engagement the previous year had made us more rigorous about vendor selection. We took the time to find a partner we actually trusted before we committed.
Marcus Holloway
SVP of Engineering - Vertex Cloud DynamicsSupport response times that exceed what we achieved with an internal team
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
Open banking changes required us to rebuild our API layer properly — compliant by design, not patched together. We needed specialist engineers, not generalists.
Soo-Yeon Choi
Product Manager - Gangnam Ventures Co LtdTechnically strong, commercially fair, and genuinely good to work with
Our stakeholder group was unusually broad — board sponsors, operational users, compliance leads, and an IT team with strong opinions. I have watched vendors handle that kind of environment badly. This team adjusted how they communicated depending on who they were talking to, managed expectations honestly when things shifted, and delivered something that each group considers a success. Getting everyone to agree on that outcome was not straightforward and they deserve credit for making it happen.

Head of Technology - Ravi Digital AgencyMulti-region setup and automated failover that we tested twice and it worked both times
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.

Project summary
A new care pathway required patient data to move between systems in a way our current architecture did not support. The integration complexity was beyond what we could handle in-house.
