AI investments

Exmore, based in Shibuya-ku, Tokyo, makes an AI-powered inquiry response application. Its SuguDesk AI chat platform is meant to streamline administrative work in medical clinics. The round amount was not disclosed on the Lounge deals desk, and we did not find it in the report we used.

Investment focus

There is too little public information to describe a stated thesis. The one confirmed deal is a seed-stage, AI-enabled healthcare software company in Japan, with the round led by another investor. He has made no public statements about check size, preferred stage or sectors that we could find, so none are given.
