Senior🎓
Top SchoolTakahiro Horikawa is a founder and CEO with 16 years of engineering experience who builds immersive XR and AI-driven experiences that bridge theatre-scale installations and head-mounted platforms like Apple Vision Pro and Quest 3. As lead engineer at curiosity, Inc. he ships story-driven MR attractions and AR playgrounds while prototyping at the intersection of spatial computing, generative AI, and sensors to turn “wow” moments into measurable engagement for venues and brands. His background spans mobile and backend engineering roles at Yahoo and startups, plus deep technical contributions to open-source projects such as OpenCV and Robolectric where he fixed core computer-vision bugs and strengthened Android testing infrastructure. A University of Tokyo-trained mathematician, he blends rigorous problem-solving with creative design—evident in projects that avoid headsets entirely to create social, location-based interactions. Practical, hands-on, and curious, he also created developer tooling (FireMobileSimulator) and brings rare end-to-end expertise from low-level algorithm fixes to large-scale visitor experiences.
