South Korea-based startup 1Self.World, operator of the hyper-personalized identifier-based digital marketing platform MyB, has raised approximately USD 1.5 million(KRW 2 billion) in a pre-Series A bridge round from Crit Ventures.

1Self.World holds a domestic patent for next-generation user-centric advertising identifier technology and is currently pursuing a U.S. patent application. This proprietary technology has been implemented in its reward-based app MyB, enhancing advertising data reliability and maximizing the effectiveness of customized targeting.

Within one year of launch, MyB surpassed 1 million cumulative users and achieved an average revenue per user (ARPU) more than four times higher than the industry average, demonstrating strong market performance.

In the third quarter of this year, the company plans to unveil MyB AdChain, a next-generation reward-based ad network that integrates an AI recommendation system with blockchain-based data verification technology. This is expected to significantly improve advertising efficiency and transparency compared to existing reward-based ad networks.

Looking ahead, 1Self.World aims to accelerate domestic and global market expansion by building an integrated digital economic infrastructure centered on MyB, encompassing advertising, rewards, and payments powered by a KRW-backed stablecoin.

Song Jae-jun, CEO of Crit Ventures, stated “1Self.World is demonstrating new possibilities in the AdTech industry through proprietary technologies leveraging AI and blockchain. We expect them to set new standards in the market and grow into a global AdTech unicorn.”

Cho Chang-hyun, CEO of 1Self.World, added “Our innovative advertising platform that combines AI with data reliability technologies can become a new standard for the global mobile ecosystem. With this funding, we will accelerate global expansion and business model diversification.”
