About Company: Unthinkable Solutions is a custom software development company. Through our journey of working as a technology partner to 100+ organizations across the globe, we realized that software engineering should not be done in silos but rather should be a user-data-driven process. To incorporate this into our value proposition, Unthinkable came up with an innovative data-driven approach for software engineering, user engagement, and user acquisition.
