Zyberno is a financial analysis platform built on first-principles valuation, giving individual investors access to institutional-grade tools. It screens over 10,000 stocks across 138 metrics including Owner Earnings, Margin of Safety, ROIC, and DCF-based intrinsic value, sourced directly from SEC filings. At the core is the Brina Gap, a proprietary framework published by founder Fabio Brina on Zenodo and SSRN. It measures the difference between a company's Fundamental Growth Rate and its Market-Implied Growth Rate via reverse DCF, making mispricing measurable rather than intuitive. The platform includes full stock reports, the Zyberno Score, Brina Matrix, Monte Carlo simulator, DCF and WACC calculator, Buffett Indicator, and options analysis tools. All valuation outputs reflect the direct result of the model, not adjusted to match consensus. Founder Fabio Brina is an independent financial researcher with 18 years in markets.
