About Us

Founded in 2020 by Dr. Ihnjea Choi and Dr. Woo Jin Chang, Septillionth Inc. is specialized in water quality monitoring systems. The company is creating an innovative hand-held digital lead detector and sensor. This technology allows the general public to conduct accurate and precise on-site water contamination testing without specialized training. While we are in the early stages with limited sales records for parts related to the detection system, we are actively collaborating with industry partners. We are in the process of developing a working prototype, and currently submitting SBIR proposals with the goal of kick-starting product development and manufacturing. Within a year, we plan to field-test the developed prototype detection system with a collaborating company.
