Institutional-grade investment intelligence for professional investors
Founded in 2025, 13Radar emerged from a simple observation: the most successful investors weren't just smart—they had access to better information. While retail investors struggled with fragmented data and delayed insights, institutional players leveraged comprehensive 13F filing analysis to make informed decisions.
We set out to democratize this advantage. Today, 13Radar transforms complex SEC filings into actionable intelligence, helping professional investors track institutional movements, identify market trends, and discover opportunities with unprecedented clarity and speed.
