Cooboo Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Sei Narita) will begin offering the MicroSaaS 'GEO Signals' on June 29, 2026 (Mon), a monitoring tool designed to continuously track brand mentions, URL citations, and competitive visibility within AI-generated responses such as Google AI Overviews, ChatGPT, and AI Mode.
