Headquartered in China (Hefei, Anhui Province) with North America sales and tech support office in USA (Los Angeles, CA), Wisdom Tech is a spin-off from the internationally renowned University of Science and Technology of China (USTC) which continues to provide R&D innovation and talented employees. The management team contains individuals with extensive entrepreneurial and managerial experiences.
The idea leading to ArcherQA® technologies originated from a research project started in 2009 at Rensselaer Polytechnic Institute (Troy, New York) — the oldest engineering school in North America. The research was funded by a large number of highly competitive NSF and NIH grants (including several R01 and fast-track STTR/SBIR grants). The research and commercialization of the ArcherQA technologies took off at USTC (Hefei, Anhui).
