Webull and Meritz Securities Launch MOUM: AI-Powered Investing for South Korea

Webull is providing the technological infrastructure for MOUM, a new AI-driven investment platform from Meritz Securities, marking a significant expansion into the South Korean retail market. By integrating proprietary AI analysis and global social features directly into a local brokerage offering, the partnership signals a shift toward borderless, intelligence-heavy trading environments for retail investors.

What was announced

Meritz Securities has launched MOUM, a next-generation investment platform powered by Webull’s technology suite. The platform is designed specifically for South Korean retail investors, providing them with direct access to U.S. equity markets alongside advanced analytical tools. A central component of the launch is Vega AI, Webull’s proprietary investment intelligence engine. This technology is designed to help investors navigate the increasing volume of financial data required for modern trading, enabling users to quickly analyze complex company filings, earnings reports, and global news cycles.

Beyond technical analysis, MOUM integrates the Webull Community, a real-time global social network that connects Korean traders with the perspectives and conversations of investors worldwide. This integration makes Meritz Securities the first brokerage in South Korea to offer both the Vega AI suite and the Webull Community features. The rollout follows a strategic partnership established between the two firms in November 2025. The platform aims to streamline the investment journey by combining local brokerage services with global market access and AI-powered insights in a single, unified interface, catering to a growing demographic of digital-native investors in the region.

"MOUM is built on a simple belief: that a truly borderless investment experience is something you build together, not alone. Our partnership with Webull is central to that vision, connecting Korean investors seamlessly to global markets, and bringing world-class technology into a single, unified journey. This launch is not a destination, but the beginning of the future of investing we are creating with our partners."

Jangwook Lee, Executive Vice President and Head of Inno Biz Division at Meritz Securities.

The companies involved

Webull Corporation is a global financial technology company listed on the NASDAQ under the ticker BULL. It has established itself as a major player in the retail brokerage space by focusing on technology-driven trading solutions and community-based investing. The company operates through various subsidiaries, including Webull Technologies Inc., which is led by CEO Jack Keating. Webull’s model typically emphasizes low-cost access to global markets paired with sophisticated technical indicators that were previously the domain of professional traders.

Meritz Securities is a prominent South Korean brokerage firm and a key entity within the broader Korean financial landscape. Under the leadership of executives like Jangwook Lee, the firm has increasingly focused on digital transformation and "AI-forward" investing experiences. Meritz has been active in seeking international partnerships to broaden the scope of its offerings for domestic clients. The collaboration with Webull represents a significant step in its strategy to integrate global market data and sophisticated AI tools into its proprietary platforms, positioning itself as a tech-centric leader in the highly competitive and digitally advanced Korean brokerage market.

What FF News has reported before

FF News has tracked the rapid expansion of both Webull and Meritz Securities as they seek to dominate the digital wealth management space across Asia. In September 2026, we reported that Webull Thailand Completes $100M Acquisition of Pi Securities to Scale Digital Wealth Management, highlighting the firm's aggressive regional growth strategy. Meritz Securities has also been active in securing high-level data partnerships; we recently covered how Bruce Markets Enters South Korea as Meritz Securities Taps Overnight U.S. Equity Data. Additionally, the firm's focus on intelligence was underscored when Benzinga and Meritz Securities Launch AI-Powered Market Intelligence for South Korean Traders, further demonstrating Meritz's commitment to equipping retail investors with professional-grade tools.

What this means

This move highlights the intensifying "arms race" in the retail brokerage sector, where simple market access is no longer a sufficient differentiator. By embedding Webull’s Vega AI and social community into Meritz’s local infrastructure, the partnership puts significant pressure on traditional Korean brokerages that rely on legacy systems and siloed data. The industry is clearly moving toward a model where the primary value-add lies in the speed of data synthesis rather than just trade execution. This launch raises questions about how quickly competitors can integrate similar AI-driven intelligence before retail capital migrates toward platforms that offer more sophisticated, borderless analytical capabilities as a standard feature.
