What is ProBors?
ProBors is a research platform that puts institutional-grade disclosure intel in front of retail investors. It continuously monitors public SEC and congressional disclosure sources and surfaces insider Form 4 filings, congressional trades, and whale moves in one real-time feed — with source links and filing-lag context instead of hiding delays. Beyond the raw feed, ProBors layers an AI research assistant that answers plain-English questions about any filing, trade, or trend and shows which sources it used, a trade detail view that overlays filings on price charts with performance since disclosure, and full politician portfolio snapshots tracking holdings, buys/sells, and sector allocation over time. The company is a bootstrapped 1-10 person startup founded June 2025 in Slovenia, led by co-founder Pier Callin. It launched on AppSumo in 2026 at two lifetime tiers ($49 and $129) and carries a 4.7/5 AppSumo rating across 16 reviews. ProBors is a research tool, not financial advice — reviewers praise its data breadth and responsive support but flag an unfinished UI, credit-gated AI chat, and the inherent lag in congressional disclosures.

Who is it for?
- Retail investors who want to see what insiders, politicians, and whales are trading without a $24K terminal
- Traders who like studying politician portfolios and whale positions for thematic or contrarian signals
- Journalists and researchers digging into congressional holdings or insider buying patterns
- Startup founders scouting competitor investors and ownership shifts
Who is it NOT for?
- Anyone expecting politician trades in real time — congressional disclosures legally lag up to 45 days
- Casual investors who check markets once a week and won't use the AI assistant
- People who hate credit-gated AI features and want a purely unlimited flat-fee tool
- Anyone looking for investment advice — this is data, not a recommendation engine
The Bottom Line
If you're the kind of investor who actually digs into what insiders and politicians are trading, ProBors is a genuinely useful research layer at a fraction of a Bloomberg terminal — and the $49 lifetime price is a no-brainer entry point while it lasts (it ends in about two days). But temper expectations: the UI is still rough, congressional data legally lags by up to 45 days, and the AI chat that makes it shine burns through its 100-credit monthly allowance fast. Buy it for the feed and the research depth, not for the polish.
