💰 CUBIG Secures Series A Funding from Iona Star, Accelerating Global Expansion

Hello, we are CUBIG, a pioneer in AI security and synthetic data.

We’re excited to share that CUBIG has raised Series A funding from UK-based Iona Star LP and Korea’s Friend Investment Partners, bringing our cumulative funding to KRW 9 billion.

Beyond capital, this round represents a strategic partnership to accelerate our entry into Europe and North America 🌍

🚀 Differential Privacy Meets Synthetic Data

CUBIG’s core innovation combines differential privacy with synthetic data, enabling AI training and analysis without ever exposing raw data.

Original datasets remain local, while only synthetic candidates are shared back — ensuring that sensitive information never leaves the owner’s environment.

This “learning without seeing the data” approach addresses one of the biggest bottlenecks in AI adoption and empowers organizations across finance 💳, healthcare 🏥, and government 🏛️ to safely leverage their data.

🔐 X-PERT: Real-World Applications

Our flagship platform, X-PERT, supports multimodal, domainless synthetic data — including text, tables, images 🖼️, and time-series.

It helps balance skewed datasets, augment rare events such as fraud detection in finance, and enables predictive simulations for HR or policy scenarios.

By safely integrating with LLMs 🤖, X-PERT enhances AI performance while maintaining compliance.

As a field-proven solution, X-PERT goes beyond demo-stage technology and is already used in mission-critical environments.

✈️ Global Expansion and Vision

With this investment, CUBIG will:

• Establish overseas subsidiaries starting in the UK

• Prioritize go-to-market strategies for Europe

• Strengthen sales and marketing capabilities

• Secure top talent 👩‍💻👨‍💻

Recognized with multiple patents, GS certifications, and government awards, CUBIG already partners with Kyobo Life, IBK Bank, and Gangnam District Office.

Our vision is to lead the global data governance market as a trusted data infrastructure company.
