CoA Nexus, Inc.

CoA Nexus, Inc. (formerly Srust, Inc.) is a Tokyo- and Menlo Park-based deep-tech HR startup that uses proprietary AI to read tens of millions of research papers and patents, visualize a scientist's real skills, and match R&D talent with companies - from university spinouts to large manufacturers. Its flagship platform, CoA Researcher, is billed as Japan's largest researcher-matching platform, supporting full-time roles and side work across biotech, chemistry, medical science and semiconductors. The company raised a roughly ¥300 million Series A in October 2025 to expand its global researcher database and go beyond the reach of conventional job ads.
