Questions & Answers

Please describe your company, your role, and the industry you operate in.
We are a Head of Digital-led organisation operating in the Retail & E-commerce 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 Retail & E-commerce operations through Game Development. 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 Game Development 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 Game Development and a strong portfolio of Retail & E-commerce 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 Game Development projects going forward.

FAQs

Will TheOne sign an NDA before we even discuss the project in detail?
Most professional shops, including TheOne, 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, it has served clients in Serbia, and its average project cost is reported at $5000000+.
Does TheOne only work locally, or take on clients elsewhere too?
TheOne isn't necessarily limited to one region and may take on clients across several countries, including Serbia, depending on market demand and business partnerships.
What's actually in TheOne's technical toolkit?
The exact stack shifts by project, but TheOne commonly works across things like React, Angular, Vue.js, Node.js, Python, .NET, Java, PHP, Flutter, React Native, native iOS and Android, and cloud platforms like AWS and Azure. For context, it has experience across industries such as Construction, Retail & E-commerce, Logistics & Supply Chain, Sports & Fitness and Events & Event Management, and its listed capabilities span E-commerce Development, Mobile App Development, UI-UX Design, Web Design and Web Development.
Does TheOne actually build with AI, or just talk about it?
Plenty of modern software teams, TheOne included, now build real AI and machine learning features — chatbots, predictive models, computer vision, and automation that goes beyond simple rule-based scripts. For context, it has served clients in Serbia, and it has experience across industries such as Construction, Retail & E-commerce, Logistics & Supply Chain, Sports & Fitness and Events & Event Management.
Would TheOne be a good fit for an early-stage startup?
Generally, yes — companies like TheOne 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 experience across industries such as Construction, Retail & E-commerce, Logistics & Supply Chain, Sports & Fitness and Events & Event Management, and it has been operating since 2004.
Can I just hire developers from TheOne to sit alongside my own team?
Usually, yes — a dedicated developer arrangement is a common option with firms like TheOne, 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 served clients in Serbia, and it has experience across industries such as Construction, Retail & E-commerce, Logistics & Supply Chain, Sports & Fitness and Events & Event Management.
Is TheOne more of an offshore setup or a local team?
That depends on where TheOne is based and who they primarily serve — some firms like this operate fully offshore, some are local-first, and plenty run a hybrid model that mixes both. For context, its listed capabilities span E-commerce Development, Mobile App Development, UI-UX Design, Web Design and Web Development, and it reports a team size of 10 - 49 professionals.
What are the actual contract options if I want to work with TheOne?
Most companies structured like TheOne give you a choice between a fixed-price contract, a dedicated team arrangement, or time-and-materials billing, so you can pick whichever lines up with your budget and how well-defined your scope already is. For context, it has served clients in Serbia, and it has experience across industries such as Construction, Retail & E-commerce, Logistics & Supply Chain, Sports & Fitness and Events & Event Management.
Has TheOne actually shipped a SaaS product before?
It's a common line of work for a company like TheOne — multi-tenant architecture, subscription billing hooked up properly, and cloud-native deployment built for a product meant to scale as a service rather than a one-off build. For context, its listed capabilities span E-commerce Development, Mobile App Development, UI-UX Design, Web Design and Web Development, and its typical hourly rate is around $25 - $49.
Can TheOne take on an old, outdated system rather than starting from scratch?
Modernizing legacy software is usually within scope for a firm like TheOne — re-platforming, refactoring old code, and moving things onto current frameworks or cloud infrastructure without necessarily rebuilding everything from zero. For context, it has experience across industries such as Construction, Retail & E-commerce, Logistics & Supply Chain, Sports & Fitness and Events & Event Management, and its average project cost is reported at $5000000+.
