Toptal Reviews
Write a ReviewERP rollout that went live on the agreed date — we know how significant that is
Flynn Buchanan / GM of Technology - Pacific Rim Commerce GroupMay 30, 2026
Project summary: B2B customer churn was concentrated among accounts that had complained about portal usability. We needed a complete redesign of the self-service experience before the next contract renewal cycle.
We gave this team an aggressive timeline, a technically complex scope, and a client-side project team that was stretched thin and not always available at the speed the engagement required. They absorbed all of that gracefully. Where they needed input they were precise about what they needed and when. Where they could proceed independently they did. The result was a delivery that landed on time despite the constraints on our side, which I regard as evidence of genuine professional maturity.
Senior-level engineering presence throughout the entire project, not just during the pitch, honest and commercially fair handling of scope changes, codebase that our internal team praised on review
Their discovery process is more rigorous than we were accustomed to and required more preparation from our side than we had initially allocated — but the quality of what followed justified every hour of it
Questions & Answers
Project execution that matched the proposal in every dimension that mattered
Danielle Westbrook / Chief Digital Officer - BlueSky Retail HoldingsApr 12, 2026
Project summary: Our internal product thinking was strong but our execution capability in this specific technology domain was limited. We needed depth, not generalism.

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
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
Sensor network and analytics layer built by engineers who understood both halves equally
Rupert Ashford / Director of eCommerce - Hargrove Retail PLCMar 11, 2026
Project summary: An international expansion required multi-currency, multi-language, and multi-warehouse capabilities that our existing platform could not support without a fundamental re-architecture.
What made the most difference in practice was the quality of the engineering judgment on this team. Not the ability to execute a specification — that is a baseline expectation. The ability to recognise when a specification was suboptimal, explain why, propose an alternative, and support the client in making a decision about it. That consultative dimension elevated the output beyond what the brief described and resulted in a product that is more fit for purpose than the one we had originally specified.
Deep domain knowledge that reduced the discovery overhead significantly, proactive risk identification before issues became incidents, delivery cadence that our stakeholders found reassuring
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
Questions & Answers
Machine learning in production that the board could see working within eight weeks
Clémentine Aubert / Head of Digital Products - Arc-en-Ciel Digital SASFeb 23, 2026
Project summary: The project had a board-facing delivery date tied to a strategic initiative. We needed a partner who would treat that date as their own, not ours.
We had worked with three agencies before this engagement. The comparison is not flattering to the others. What distinguished this team was a systematic approach to understanding the problem before proposing a solution — something that sounds obvious and is practiced far less often than it should be. The delivery phase ran to schedule, the codebase is clean enough that our internal engineers made positive comments during handover review, and we have not logged a critical incident in five months of live operation. We intend to use them for our next phase of work.

Their insistence on a detailed functional specification before development began felt like friction at the time. In retrospect, it was the reason the development phase ran without the ambiguity that has derailed similar projects for us previously

Professional team that delivers excellence every time
Nathan Clarke / Investment Director - UK Ventures LtdFeb 08, 2025
Project summary: We required a custom platform that would give us a measurable competitive advantage in our market.
From day one, the team felt like an extension of our own organisation. They immersed themselves in our domain, challenged us to think bigger, and delivered a solution that is both technically sound and strategically valuable. The project came in on time and within budget, which is rare for an engagement of this complexity. We are delighted with the outcome and look forward to a long-term partnership.
Outstanding code quality, thorough documentation, smooth knowledge transfer, excellent post-launch support
Initial onboarding took a couple of extra days, but the team hit full stride very quickly

Best technology partner we have ever worked with
Aisha Patel / Director of Strategy - Mumbai VenturesJun 04, 2022
Project summary: We required a custom platform that would give us a measurable competitive advantage in our market.
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.
