Road to RESoft Timeline
Our journey to RESoft™ began with the establishment of the software company, HIS, which attained market dominance by capturing 47% market share. Subsequently, our next venture, Amkai, achieved an impressive market penetration of 83% as of 2019. Along this path, we garnered multiple accolades and awards, including two software excellence awards from Microsoft.

These experiences have been invaluable in shaping the creation of RESoft™. Recognizing the inadequacies within the real estate software industry in providing a seamless, all-encompassing solution, we resolved to address this gap. The culmination of our collective knowledge and understanding has resulted in the development of our most advanced, best software to date, RESoft™.

Our vision is clear: to offer the most comprehensive real estate software solution available, free from integration requirements or dependency on third-party components. We are committed to ensuring that our software stands out for its efficiency, providing a diverse array of powerful tools designed to support real estate brokerages and their agents.
