Best technology partner we have ever worked with

Robert Martinez / Operations Manager - Solutions Group
Verified
Jun 27, 2022

Project summary: Our hospitality group required a guest experience platform integrating PMS, CRM, and loyalty programmes.

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.

PROS

Deep technical expertise, professional project management, responsive support, great value

CONS

None — every aspect of the engagement exceeded our expectations

Questions & Answers

Please describe your company, your role, and the industry you operate in.
We are a Operations Manager-led organisation operating in the Travel & Hospitality sector. My role involves overseeing strategic technology decisions and vendor partnerships. We have been growing steadily and needed a trusted partner to help us scale our digital capabilities.
What specific problem or business challenge led you to hire this company?
Our primary challenge was modernising our Travel & Hospitality operations through UI/UX Design. Legacy systems were limiting our agility and we needed a solution that could scale with our growth ambitions and integrate with our existing infrastructure.
What services did the company provide for your project?
They delivered a comprehensive UI/UX Design engagement covering requirements analysis, solution architecture, full-cycle development, QA testing, deployment, and post-launch support. The scope was well-defined and executed without scope creep.
Why did you choose this company over other providers you considered?
Their demonstrated expertise in UI/UX Design and a strong portfolio of Travel & Hospitality projects set them apart during our evaluation. The discovery call gave us confidence they truly understood our domain, not just the technology.
How clearly did the company understand your requirements and business goals?
Exceptionally well. They ran a structured discovery process, asked insightful questions, and produced a detailed requirements document that captured nuances we hadn't even articulated ourselves. That foundation made the entire project smoother.
How was your overall experience with their communication and project management?
Outstanding. We had a dedicated project manager, weekly status calls, a shared project board, and same-day responses to queries. There were no surprises — risks were flagged early and resolved before they became issues.
Did the company deliver the project on time and within your expected budget?
Yes, the project was delivered on the agreed date and within budget. Their estimates were realistic and they managed scope carefully, flagging any potential changes before they impacted the timeline or cost.
What tangible results or business impact have you seen since the project was completed?
Significant. Since go-live we have seen measurable improvements in operational efficiency, customer satisfaction scores have risen, and the solution has already paid back a substantial portion of the investment. The team built something we are genuinely proud of.
What did you like most about working with this company?
Their genuine investment in our success. They didn't just execute a spec — they brought ideas, challenged assumptions, and cared about the outcome as much as we did. The quality of the codebase and documentation also stood out.
Would you recommend this company to others, and would you work with them again?
Absolutely and without hesitation. We have already referred two colleagues, and we are actively scoping the next phase of work with them. They are our go-to partner for UI/UX Design projects going forward.

FAQs

What kind of software work does DTT take on?
DTT typically covers the standard range of software development work — mobile apps, web platforms, custom internal tools, UI/UX design, cloud infrastructure, AI integrations, and larger enterprise builds. Its core focus areas include Custom Software Development, Game Development, Mobile App Development, UI-UX Design and Web Design.
What happens with DTT after the project actually launches?
Like most established software teams, DTT typically sticks around post-launch for ongoing maintenance — bug fixes, performance tuning, security patching, new feature work, and general technical support. For context, it has experience across industries such as Environmental Services, Education, Mining & Metals, Travel & Hospitality, Information Technology and Manufacturing, and it reports a team size of 50 - 249 professionals.
Will DTT sign an NDA before we even discuss the project in detail?
Most professional shops, including DTT, expect to sign a Non-Disclosure Agreement before getting into specifics — it's a fairly standard ask and a reasonable one to make before sharing anything sensitive. For context, its listed capabilities span Custom Software Development, Game Development, Mobile App Development, UI-UX Design and Web Design, and its average project cost is reported at $25000+.
What should I expect to pay to work with DTT?
What DTT charges comes down to a handful of variables — how complex the project is, the number of development hours involved, the tech stack required, team size, and which engagement model you pick. Based on available data, DTT's typical hourly rate is around $100 - $149, with an average project cost of $25000+.
What makes DTT worth considering over other options?
What tends to set DTT apart usually comes down to some mix of technical depth, relevant industry experience, how clients describe working with them, their development approach, communication habits, and whether they can actually deliver something that scales. Founded in 2010, the company has built a track record of delivering projects across various industries.
Can I just hire developers from DTT to sit alongside my own team?
Usually, yes — a dedicated developer arrangement is a common option with firms like DTT, where you get engineers working exclusively on your project as an extension of your in-house team rather than as a separate outsourced unit. For context, it has experience across industries such as Environmental Services, Education, Mining & Metals, Travel & Hospitality, Information Technology and Manufacturing, and its listed capabilities span Custom Software Development, Game Development, Mobile App Development, UI-UX Design and Web Design.
Would DTT be a good fit for an early-stage startup?
Generally, yes — companies like DTT tend to work well with startups because of what they typically offer: MVP builds, product strategy input, architecture that can scale later, and dedicated teams that keep costs manageable while still moving fast. For context, it has served clients in Netherlands, and its average project cost is reported at $25000+.
Roughly how long does a project with DTT take start to finish?
It depends heavily on scope. A lean MVP might be a matter of weeks, while a full enterprise system or a larger digital transformation project can stretch into months once you factor in development, testing, and deployment. With a team of 50 - 249 professionals, DTT can scale resources based on project urgency.
Does DTT only work locally, or take on clients elsewhere too?
DTT isn't necessarily limited to one region and may take on clients across several countries, including Netherlands, depending on market demand and business partnerships.
