Full disclosure: Dombey Capital is our own research service and our top pick here, for the reasons below. The section on where it falls short is there so you can judge whether it fits your process.
Which part of Quiver are you replacing?
Quiver Quantitative collects public and web data and links it to stock tickers. Its site lists congressional trading, insider trading, government contracts, corporate lobbying, institutional holdings, patents, layoff notices, social sentiment from WallStreetBets, app ratings and Wikipedia pageviews, plus backtesters, strategies, alerts and a screener.
Most readers use two or three of those. The congressional trades, insider filings and 13F holdings are the most popular, and each has a dedicated alternative. The more unusual datasets, such as app ratings or pageviews, have few direct replacements, though the government records behind contracts and lobbying are free at the source.

How we compared these tools
We compared these tools from vendor documentation, pricing pages and public product pages, read in October 2026. We did not run trials of the paid plans, and we make no claims about the accuracy of any dataset or about the returns of any signal or strategy.
| Criterion | Weight | What it measures |
|---|---|---|
| Catalyst context | 25% | Whether the tool ties a data point to a dated event and what it means for value |
| Dataset coverage | 20% | Congressional, insider, fund holdings and other datasets offered |
| Timeliness and alerts | 15% | How fast filings appear and whether you can be notified |
| Link to primary source | 15% | Whether each data point leads back to the filing or record |
| Cost and friction | 25% | Price of the plan you would need, and free tiers |
We weighted catalyst context most because a congressional trade or an insider purchase is a prompt for research, not a conclusion, and special situations depend on what a dated event does to value. If you weight dataset breadth most, Unusual Whales and HedgeFollow move up; if you weight cost, OpenInsider, HedgeFollow's free pages and the official sources lead.

Where Dombey falls short
- Narrow coverage. Dombey covers a short list of special situations. Most insider trades and congressional disclosures concern companies Dombey will never cover.
- No broad stock data terminal. No datasets, screeners, backtests or alerts on filings. You still need a data site or EDGAR.
- Small team. A small team limits how many situations it can follow properly.
- Pen-name author. Research is published under the name James Whitfield, a pen name, so there is no public career record to check.
- Short history. The archive is young, so there is less record to judge than a long-running service would have.
Where this goes wrong
Alternative data is easy to over-read. Each dataset has a lag and a blind spot.
- Congressional trades are reported up to 45 days after the trade, often in value ranges, and many are made by spouses or managed accounts.
- 13F holdings are as of quarter end and filed up to 45 days later, long only, and exclude most short positions.
- Insider sales are often scheduled under Rule 10b5-1 plans or made for taxes and diversification.
- Contract awards may be ceilings, not revenue, and can be spread over many years.
Read the filing behind any data point, and ask whether it changes a dated catalyst. Our list of insider buying tools and our explainer on hard vs soft catalysts help with both steps.
