The ZirkelTech team was instrumental in developing our Personal Finance platform - MoolahMate. Their expertise ensured a seamless integration with another solution provider while also incorporating robust security. They met all the deadlines, responded to our queries quickly and stayed within budget. Their ability to listen, suggest ideas, dedication and professionalism make them an invaluable partner. It has been a pleasure to work with them as a partner in our journey to deliver a great solution for our customers.
From the very first discovery workshop, the ZirkelTech team demonstrated a rare combination of deep technical knowledge and genuine curiosity about our manufacturing operations. Rather than proposing a generic off-the-shelf solution, they invested heavily in understanding our specific OEE (Overall Equipment Effectiveness) measurement methodology, our rejection-tracking workflows, and our compliance obligations under IATF 16949. This groundwork paid dividends throughout the entire project.
