LGC (Larry Group Corp) is an AI-native automation company headquartered in Tokyo, founded on December 1, 2023. We design and operate fully autonomous smart homes, hotels, and commercial buildings that manage comfort, safety, and energy as one intelligent system. Our IoT and machine-learning stack learns from occupants, optimizes in real time, and delivers measurable savings—often reducing energy use by up to 40%—while elevating guest experience and system uptime. We serve clients across Asia and Africa through partner hubs in Seoul, Kampala (Uganda), and Taipei. Our mission is to make modern living simpler, safer, and dramatically more efficient, setting the global standard for intelligent, sustainable spaces.
LGC was founded by Larry Luyombya, a Tokyo-based senior technology leader and entrepreneur who has led large-scale platform programs at Mercari, contributed to software-first mobility at Woven by Toyota, and delivered high-impact initiatives at Google across APAC. Combining hands-on AI/ML, IoT, and cloud expertise with product leadership, Larry built LGC to transform buildings into autonomous, self-optimizing environments. Today, we deliver turnkey autonomy for buildings—sensing, control, analytics, and AI agents—alongside energy optimization with verified savings targets, integrated security and safety orchestration across devices and systems, and scalable solutions for both retrofits and new builds, designed for compliance, resilience, and 24/7 reliability.
