CUBIG, a startup specializing in synthetic data solutions using differential privacy technology, has secured undisclosed funding from CNTTech and DB Capital. The company previously received seed investment from NAVER D2SF last year.

CUBIG has developed a proprietary State-of-the-Art (SOTA) algorithm that generates synthetic data using differential privacy technology, ensuring that the original data cannot be inferred and remains secure.

Differential privacy works by injecting noise into data, effectively anonymizing sensitive information. As global competition in AI intensifies, this technology is gaining attention as a key solution for data privacy concerns and for breaking down the silos that prevent data sharing between organizations. Leading companies like Apple, Amazon, and Facebook have already integrated differential privacy into their services.

CUBIG’s synthetic data solution applies this technology to AI models, producing data that closely resembles the original while minimizing the risk of exposing sensitive information. The company also offers ‘DTS (Data Transform System),’ a tool that allows users to easily generate synthetic data locally without any coding knowledge, simply by using a mouse.

This solution enables companies to generate sensitive data safely within their own servers without uploading it to external clouds, significantly improving the utility of internal data. CUBIG’s solution retains up to 99% of the original data’s performance and can be applied across industries that handle sensitive information, such as finance and healthcare.

CNT Tech’s CEO, Jeon Hwa-sung, commented, “With the increasing demand for AI training data, the global synthetic data market is growing rapidly in many countries. CUBIG is aiming for global expansion, including entering markets like Korea, where data shortages are a serious issue. We expect quick commercialization.”

Kang Seok-min, team leader at DB Capital, added, “Synthetic data is essential to solving the data shortage caused by the expansion of the AI market. CUBIG stands out for its solution, which addresses security concerns in the synthetic data generation process.”

CUBIG’s CEO, Jung Min-chan, said, “This investment recognizes our technological strength and market potential. With this funding, we plan to accelerate the growth of the synthetic data market in the U.S., where the shortage of AI datasets is particularly critical.”
