AtradianAll comparisonsAlternative data (Congress, insiders, government contracts)
Quiver and Atradian both use public filings most investors never read: congressional disclosures, insider transactions and government contracts. Quiver's core product is the datasets themselves, delivered for you to explore. Atradian's focus is what those datasets mean for your holdings today, with the reasoning and grading attached.
Quiver Quantitative
Quiver Quantitative provides alternative-data feeds and screens built on public sources, including congressional trading, insider transactions and government contract data, with an API for developers.
Atradian
Atradian includes congressional trades, insider buys, 13F superinvestor holdings and US government contract awards inside a daily brief, so each dataset is weighed against regime, news and your own rules rather than read alone.

Best for Quiver Quantitative
Developers and quants who want raw alternative-data feeds and an API to build their own screens.
Best for Atradian
Investors who want those datasets interpreted against their holdings and the current regime.
Does Atradian have an API like Quiver?
No. Atradian is a web app and doesn't offer a public data API. If you need raw feeds to build your own models, Quiver is the better fit.
Why is congressional trading data delayed?
Members of Congress generally have up to 45 days after a trade to report it, so every congressional trade dataset lags the market. Atradian treats these trades as one input to weigh, not a live signal.
Can I use both?
Yes. Some users pull raw feeds from Quiver for their own models and use Atradian for the daily read and the regime context.
See the evidence, not just the argument.
Atradian grades its own AI against forward outcomes and shows the backtest for every strategy it trades.
