Unlike most market research or consulting firms we take an interdisciplinary approach that combines hypothesis-driven research with the best of creative and design-thinking, and philosophical and critical-thinking skills. This enables us to tailor our studies to your specific strategic needs and explore opportunities that the rest of the world is overlooking. We not only look at averages, but also explore outliers, because this is where disruptive innovation is born. We love complex and ambiguous challenges, and our methodology depends on deep conceptual and quantitative analysis. However, because our work is tailored to your organization's specific needs from the very beginning, the results can also be conveniently integrated into your workflow, and lead to clear and decisive actions. We know how successful research and innovation consulting is done, and Justkul Inc. has been founded with the belief that it can be done better.
