MettleSol Reviews

Zero-trust implementation that satisfied our enterprise client security questionnaire first pass

Project summary: Our mobile app had a 2.9-star average review score. The two themes in every negative review were speed and booking flow complexity — both were solvable with the right engineering partner.

The thing that retrospectively seems most significant is how little drama there was. Complex technology projects tend to accumulate incidents, escalations, and tense conversations. This one did not. Problems were surfaced before they became incidents. Scope changes were handled with process rather than conflict. Risks were managed rather than avoided. That level of maturity is rare in my experience and it made the delivery feel almost effortless from our side, which I know it was not from theirs.

PROS

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

CONS

We underestimated the input required from our subject matter experts during the requirements phase. The team flagged this early but our resource planning did not fully reflect it — our responsibility, not theirs

Questions & Answers

Please describe your company, your role, and the industry you operate in.

As Chief Digital Officer at Cerrado Tech SA I oversee technology investment and delivery across our Travel & Hospitality operations in Brasília, Brazil. We are a commercially focused business and our technology choices are always evaluated in terms of their direct contribution to business outcomes rather than technical elegance alone.

What specific problem or business challenge led you to hire this company?

A competitive threat had accelerated our roadmap. We had planned a significant Cybersecurity investment for the following year. External pressure moved that timeline forward by six months and required us to find an external partner rather than attempting to build internally in the time available.

What services did the company provide for your project?

The scope covered the full Cybersecurity lifecycle: discovery and requirements definition, solution architecture, iterative development across twelve sprints, integration testing, performance validation, production deployment, and a structured four-week hypercare period. They also provided system documentation and a knowledge transfer programme for our internal team.

Why did you choose this company over other providers you considered?

A trusted peer in the Travel & Hospitality sector had used them for a comparable Cybersecurity engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Cybersecurity depth, and demonstrated delivery discipline was the deciding factor.

How clearly did the company understand your requirements and business goals?

Comprehensively. The discovery phase they ran was more thorough than anything we had experienced with previous vendors. They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.

How was your overall experience with their communication and project management?

Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.

Did the company deliver the project on time and within your expected budget?

Yes to both. There was a single sprint where a dependency on a third-party API introduced a one-week delay. The team identified it three weeks in advance, presented two mitigation options, and we agreed on an approach that recovered the schedule within the same sprint cycle. That level of foresight is what separates good project management from reactive problem management.

What tangible results or business impact have you seen since the project was completed?

We went live four months ago. User adoption exceeded the target we had set by 23 percent in the first month. Support ticket volume has dropped measurably. The features we had deferred because the previous architecture made them prohibitively expensive to build are now in development. The platform they built has opened our roadmap.

What did you like most about working with this company?

The continuity of the team. The engineers who participated in the discovery sessions were the engineers who built the system. That consistency of institutional knowledge across a six-month project has a value that is difficult to quantify but easy to notice when it is absent. Every conversation built on the previous ones.

Would you recommend this company to others, and would you work with them again?

Yes, without reservation. I have already made two direct referrals within my Travel & Hospitality network — in both cases to peers facing Cybersecurity challenges similar to ours. I gave those referrals with confidence because I knew the experience I described was reproducible, not the result of exceptional circumstances on our engagement.

A development partner who treated our roadmap as carefully as their own

Project summary: Unplanned downtime had become our single largest cost driver and our data showed that predictive maintenance could address the majority of it — if we had the right infrastructure to act on it.

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.

PROS

Production system that has performed as specified since go-live without remediation work, documentation thorough enough to support internal maintenance, knowledge transfer that left our team genuinely capable

CONS

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

Please describe your company, your role, and the industry you operate in.

I lead technology at Shannon Tech Solutions Ltd, a growth-stage Manufacturing business based in Dublin, Ireland. As VP of Engineering my remit spans product engineering, platform operations, and strategic vendor partnerships. We had reached an inflection point where our internal capacity was not sufficient to execute our roadmap at the pace our market required.

What specific problem or business challenge led you to hire this company?

Regulatory requirements in our Manufacturing segment had changed and the compliance timeline was set by our regulator, not by us. The Software Development changes required were significant enough to justify engaging a specialist partner rather than diverting our internal team from the product roadmap.

What services did the company provide for your project?

Primarily Software Development, with adjacent work in solution architecture and quality assurance. They were responsible for the full build from requirements through to go-live, including integration with four existing systems in our technology landscape. The breadth they covered without requiring additional vendors was commercially and logistically valuable.

Why did you choose this company over other providers you considered?

We had a failed engagement behind us and were more rigorous in our selection process as a result. We asked detailed questions about how they managed scope change, how they handled estimation, and how they communicated problems. The answers were specific, evidenced, and consistent across the team members we spoke to. That gave us confidence that the process was real rather than rehearsed.

How clearly did the company understand your requirements and business goals?

Better than we managed ourselves going in. The workshops they facilitated surfaced assumptions we had not examined and exposed three requirements that were in direct conflict with each other. Resolving those before development began saved us what would certainly have been significant rework later in the project.

How was your overall experience with their communication and project management?

Professional and efficient. The project manager maintained a clear view of the critical path at all times and communicated changes to it transparently. The one significant scope adjustment we made mid-project was handled through a clean change request process — fairly priced, clearly documented, and absorbed without disrupting the overall timeline.

Did the company deliver the project on time and within your expected budget?

Yes. I had privately built a contingency expectation into my planning given the project complexity and the number of integrations involved. None of that contingency was needed. The delivery landed on the agreed date and the final invoice matched the approved budget to within a fraction of a percent. That outcome is rarer than the industry acknowledges.

What tangible results or business impact have you seen since the project was completed?

The most direct measure is the performance of the system in production. In the five months since go-live we have had zero P1 incidents, our page performance scores have improved across every Core Web Vitals metric, and two enterprise clients who had cited our previous platform limitations during contract negotiations have since renewed without that objection arising.

What did you like most about working with this company?

The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.

Would you recommend this company to others, and would you work with them again?

Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Manufacturing sector looking for Software Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

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 thing that retrospectively seems most significant is how little drama there was. Complex technology projects tend to accumulate incidents, escalations, and tense conversations. This one did not. Problems were surfaced before they became incidents. Scope changes were handled with process rather than conflict. Risks were managed rather than avoided. That level of maturity is rare in my experience and it made the delivery feel almost effortless from our side, which I know it was not from theirs.

PROS

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

CONS

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

Project Cost$150,000 to $499,999

Questions & Answers

Please describe your company, your role, and the industry you operate in.

As Director of eCommerce at Hargrove Retail PLC I oversee technology investment and delivery across our Gaming & Gambling operations in Manchester, UK. We are a commercially focused business and our technology choices are always evaluated in terms of their direct contribution to business outcomes rather than technical elegance alone.

What specific problem or business challenge led you to hire this company?

Regulatory requirements in our Gaming & Gambling segment had changed and the compliance timeline was set by our regulator, not by us. The Game Development changes required were significant enough to justify engaging a specialist partner rather than diverting our internal team from the product roadmap.

What services did the company provide for your project?

End-to-end Game Development delivery with particular depth in the integration and data migration components, which were the highest-risk elements of the programme. They supplemented this with a dedicated QA resource throughout development and a documented runbook for our operations team at handover.

Why did you choose this company over other providers you considered?

We ran a structured shortlisting process across five vendors. The technical evaluation eliminated two immediately. Of the remaining three, this team's proposal was differentiated by the specificity of their Game Development approach and the evidence base they provided — reference projects in Gaming & Gambling contexts, not generic case studies. The reference calls confirmed a track record that the proposal had described accurately.

How clearly did the company understand your requirements and business goals?

Thoroughly and precisely. The requirements document they produced was detailed enough that our QA team used it directly to write acceptance criteria. Every user story had a defined business objective attached. Nothing was left to interpretation. That discipline in the requirements phase paid dividends throughout development and testing.

How was your overall experience with their communication and project management?

Outstanding. The discipline around asynchronous communication was particularly effective given the time zones involved between Manchester, UK and the delivery team. Written updates were specific and consistent, response times were same-day for anything that required a decision, and nothing fell through the cracks across a six-month engagement.

Did the company deliver the project on time and within your expected budget?

On time and within the approved budget. The estimation accuracy was notable — they had broken the work down in sufficient detail during discovery that their forecast proved reliable throughout, rather than being a number that shifted with every change in scope. We received one change request and it was for scope we had introduced ourselves.

What tangible results or business impact have you seen since the project was completed?

Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the Game Development work are meaningful: session duration up, conversion rate up, error rate down, and our NPS for the digital touchpoint has improved by eleven points. Our account managers report that the new capability is coming up positively in client conversations.

What did you like most about working with this company?

The continuity of the team. The engineers who participated in the discovery sessions were the engineers who built the system. That consistency of institutional knowledge across a six-month project has a value that is difficult to quantify but easy to notice when it is absent. Every conversation built on the previous ones.

Would you recommend this company to others, and would you work with them again?

Yes, without reservation. I have already made two direct referrals within my Gaming & Gambling network — in both cases to peers facing Game Development challenges similar to ours. I gave those referrals with confidence because I knew the experience I described was reproducible, not the result of exceptional circumstances on our engagement.

Project summary: Multi-touch attribution across our media mix had become the most-requested capability from every client in our portfolio. We could not deliver it without rebuilding our data layer.

I came into this engagement as a sceptic. We had been through a failed implementation with a previous vendor and I had high standards for what evidence of competence looked like before I would trust a partner with our core systems. This team earned that trust progressively — through the quality of the discovery documentation, the rigour of the technical proposals, the consistency of the sprint deliveries, and ultimately the stability of the production system. I no longer lead with scepticism when recommending them.

PROS

Clear and consistent communication adapted appropriately for both technical and non-technical stakeholders, shared tooling that gave our team real-time visibility, reliable sprint delivery throughout

CONS

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

Please describe your company, your role, and the industry you operate in.

I lead technology at Odra Tech Studio, a growth-stage Advertising & Marketing business based in Wrocław, Poland. As CTO my remit spans product engineering, platform operations, and strategic vendor partnerships. We had reached an inflection point where our internal capacity was not sufficient to execute our roadmap at the pace our market required.

What specific problem or business challenge led you to hire this company?

Regulatory requirements in our Advertising & Marketing segment had changed and the compliance timeline was set by our regulator, not by us. The Quality Assurance & Testing changes required were significant enough to justify engaging a specialist partner rather than diverting our internal team from the product roadmap.

What services did the company provide for your project?

The core engagement was Quality Assurance & Testing delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.

Why did you choose this company over other providers you considered?

The quality of the questions they asked during the briefing process was the first indicator. Vendors who ask precise questions in the sales phase tend to apply the same rigour during delivery. That hypothesis proved accurate. The technical proposal was substantive, the team structure was senior throughout, and the pricing was transparent.

How clearly did the company understand your requirements and business goals?

Comprehensively. The discovery phase they ran was more thorough than anything we had experienced with previous vendors. They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.

How was your overall experience with their communication and project management?

Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.

Project summary: Our trading platform had been extended incrementally for seven years. Latency was degrading, technical debt was compounding, and a clean rebuild was no longer optional.

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.

PROS

Commercially transparent throughout — no hidden assumptions, no bill shock at the end, change requests that were fair and clearly explained rather than used as a margin-recovery mechanism

CONS

The engagement was priced at the quality level rather than the budget level. We evaluated the alternatives and concluded that the delta was a reasonable premium for the reduction in delivery risk

As Chief Digital Officer at Southern Cross Technology I oversee technology investment and delivery across our Financial Services operations in Sydney, Australia. We are a commercially focused business and our technology choices are always evaluated in terms of their direct contribution to business outcomes rather than technical elegance alone.

What specific problem or business challenge led you to hire this company?

A competitive threat had accelerated our roadmap. We had planned a significant Data & Analytics investment for the following year.

The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.

Did the company deliver the project on time and within your expected budget?

The project landed on time. The budget was managed within the agreed ceiling, which included one client-driven scope addition that was quoted fairly and handled without affecting the original delivery stream. The discipline around budget transparency throughout meant there was no surprise at invoice stage.

What tangible results or business impact have you seen since the project was completed?

The ROI case we presented to our board was conservative by design. Current performance against the financial model suggests we will hit the projected payback point in under twelve months against an eighteen-month target. The operational efficiency gains in particular have exceeded the model, in part because the quality of the data the new platform generates supports decisions that the previous system could not.

What did you like most about working with this company?

The continuity of the team. The engineers who participated in the discovery sessions were the engineers who built the system. That consistency of institutional knowledge across a six-month project has a value that is difficult to quantify but easy to notice when it is absent. Every conversation built on the previous ones.

Project summary: As a technology business ourselves we apply the same scrutiny to our vendor selection that our clients apply to us. We needed a delivery partner who could meet a standard we would be comfortable being measured against.

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.

PROS

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

CONS

The quality of documentation they produce means our team needed to set aside dedicated review time to do it justice — a minor scheduling point rather than a genuine criticism

Please describe your company, your role, and the industry you operate in.

I lead technology at Rheintal Digital AG, a growth-stage Information Technology business based in Düsseldorf, Germany. As Chief Innovation Officer my remit spans product engineering, platform operations, and strategic vendor partnerships. We had reached an inflection point where our internal capacity was not sufficient to execute our roadmap at the pace our market required.

What specific problem or business challenge led you to hire this company?

We had a defined product vision for our next phase of growth in the Information Technology market but lacked the engineering depth internally to execute it. The IT Managed Services requirements in particular required specialist experience that we could not realistically recruit for on the timeline our business plan required.

What services did the company provide for your project?

The core engagement was IT Managed Services delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.

Would you recommend this company to others, and would you work with them again?

Yes. I would add the context that this is not the cheapest option in the market and they are selective about the engagements they take on. If your primary criterion is price, there are alternatives. If you want a technology partner who can be trusted with a complex IT Managed Services programme in the Information Technology space and will deliver against a serious brief, this is the team.
