13Radar monitors institutional investment activity by analyzing SEC Form 13F filings and real-time insider trades. It lets investors spot trends and high-conviction stock ideas by following what Wall Street's top funds and corporate insiders are buying and selling. The platform tracks over 10,000 investment firms managing $50 trillion in assets, analyzes 300,000+ reports, and surfaces curated signals like cluster buys and C-suite purchases before they hit mainstream news.
Features include portfolio change tracking by quarter, sector-level insights, historical backtesting tools, and an insider screener. The maker says most of the coding was built with Claude Code, with additional AI assistance across research, design, and prototyping.
