Real-time SEC Form 4 insider trading tracker with cluster-buy detection when 2+ insiders accumulate the same stock
Insider Hawk tracks SEC Form 4 filings in real time and turns them into a single readable surface: a "Latest Insider Activity" table of trades from corporate insiders, plus a dedicated "Insider Cluster Buys" module that flags stocks where two or more insiders are buying together. When half a C-suite quietly accumulates the same ticker, the table puts the cluster, the total dollar value and the market cap in one row.
The site is the work of Biron Clark, who has spent a decade in digital marketing — not programming. In his LinkedIn piece Can a Marketer Actually Vibe-Code a Working App? he states it plainly: "I built the site, called Insider Hawk, with the vibe-coding platform Lovable." That matters for what this entry represents: a working data product fed by the US federal securities disclosure stream, shipped by someone whose background is marketing copy, not APIs.
The design is unusually opinionated for a fintech side project: cluster buys get their own tab and filter because simultaneous insider buying is historically a stronger signal than any single insider's trade. Whether or not you believe insider data is alpha, the site is a clean, live example of the zero-to-shipped story vibe coding promises — data in, judgment out, no engineering team required.
