What did you find most impressive or unique about this company?
The most unique aspect of working with YOONG was how seamlessly they integrated into our existing product ecosystem. They felt less like an external agency and more like a natural extension of our internal engineering and product teams. Their agility in handling changing product needs and their disciplined approach to meeting a fixed, critical deadline were highly impressive. They bring a rare combination of strong technical execution and proactive communication
Are there any areas for improvement or something YOONG could have done differently?
Because their engineering quality and understanding of the regulatory logic were so strong, we would have loved to see them challenge some of our initial scope assumptions even earlier in the discovery phase. They have great product instincts, and leaning into that proactive advisory role right from day one would add even more value to the partnership.
