    Stakk has delivered a high-quality product that we are pleased with. Their hybrid model offers great value for money and grants clients to strong technical capacity but also direct contact with management in the UK which really helps with transparency, communication, and ensuring the project is being delivered on thime. The team suggests improvements and meets most deadlines.At the start of the project, I drafted a huge product requirements document that included all the user journeys, my vision for the brand, including the colors and the rest of the brand, and the desired functionalities. I gave this document to Stakk, and they've executed the requirements.

Stakks team exhibited clear expertise, with every stage thoughtfully planned from the outset. Any adjustments needed to align with our processes were managed quickly and efficiently. Their professionalism and dedication to client satisfaction were exceptional, leaving us thoroughly impressed.
