01 · Why this exists

Apex G-Score was built from the inside.

“I once held 51% of a company with $35 million in annual revenue. My control over its management was zero.”

Apex G-Score was not designed in an academic lab or a consulting firm. It was built by a shareholder who watched governance failures destroy value from the inside — not once, but repeatedly, across multiple companies.

As both a minority and a controlling shareholder in listed and private Korean companies, I went through the full range of corporate governance proceedings under Korea’s Commercial Act — director injunctions, accounting inspections, shareholder meeting challenges, damages claims. Through these proceedings, I learned where governance actually breaks down — not in theory, but in practice.

The patterns were consistent: companies that disclosed everything but concentrated decision-making in a few hands. Boards that existed on paper but never exercised independent judgment. Related-party transactions that were individually legal but collectively extractive. Value extraction channels invisible to conventional analysis.

Existing governance ratings could see none of this. They measured whether governance institutions existed, not whether they worked. They counted board seats and ticked compliance boxes; they did not read the balance of power inside the company, nor the conflict-of-interest architecture surrounding it. That is what Apex G-Score was built to measure.

The framework reads public regulatory filings and identifies structural distress patterns that precede the distress event, often by quarters or years — across eight Asian markets, on a monthly cadence, using locally calibrated variables tuned to each market’s specific pathology. Not one framework transplanted across jurisdictions, but eight domain-specific lenses built on a common architecture.

Founder & CEO

Yunjung (Michelle) You is a governance researcher and analyst who designs data-driven methodologies for evaluating corporate governance structures.

Her expertise combines quantitative research with sustained practice as both minority and controlling shareholder in Korean capital markets. Through direct involvement in corporate governance proceedings under Korea’s Commercial Act, she has developed practitioner-level understanding of how value extraction operates in controlling-shareholder environments: how transactions are structured to appear compliant, how information is selectively disclosed or withheld, and how decision-making power is concentrated behind procedural facades.

Her cross-market research spans Korean chaebol structures, Indian promoter-dominated firms, Taiwanese family-controlled groups, Thai conglomerate governance, and Japanese cross-shareholding systems — demonstrating that governance risk follows universal structural patterns even when the specific variables differ by jurisdiction.

From lived experience to quantitative infrastructure.

What began as direct shareholder practice in Korean capital markets has been extended and validated into a cross-market dataset. The numbers below describe coverage, cadence, and predictive signal.

Kill Switch crash odds
Aggregate single-day crash likelihood for issuers on Apex Kill Switch tier versus the baseline universe — validated on Hong Kong coverage.

Validation spans retrospective landmark cases across Asian capital markets — from Korean audit-opinion failures, through Singaporean distress events, to Hong Kong governance collapses — each confirming that structural signals manifest in regulatory filings before the distress event reaches equity markets.
