Client reviews and testimonials
Real feedback from the teams we have built with – banks, fintechs and product companies. Every review here is from a named client, linked to the work behind it.
We needed an Android SDK developed under a tight timeline, and their team delivered a flexible, user-friendly solution that integrated seamlessly into our ecosystem. Their transparent approach, proactive communication and commitment to quality made the collaboration smooth and efficient.
Having started development from scratch, we came to the expected result quickly – the first users went to the application after 5 months. The PWA approach was a perfect fit: omnichannel, cross-platform and cost-effective, with one team building the app and the mobile wrappers.
The WislaCode team delivered on time and with outstanding quality. Everything was trackable, visible and manageable, and they controlled timing and budgets while minimising our costs without compromising quality. In some cases the work exceeded our expectations – the contractor initiated improvements to achieve the best possible result.
The more complex and uncertain goals were converted into 30% ROI. By the end we were left with a detailed roadmap of clear milestones, able to be converted into tangible KPIs, and neat ideas of what to action next. Every part was done on time, even when priorities changed.
The outcomes were clear: 30% less travel time, 20% more visits per day, lower operational costs and stronger financial performance. Within just three weeks they delivered a proof of concept that already showed tangible results, which made it easy to commit to a full-scale rollout.
