What WhaleWisdom is

WhaleWisdom is a 13F research archive. It tracks institutional 13F filings, 13D/G disclosures, insider transactions and mutual fund holdings, with a backtester, an Excel add-in and an API. Its paid tiers are billed quarterly.

Where WhaleWisdom is stronger

13F history back to 2001. That archive is the deepest in the category and 13F Pro does not match it — if you are backtesting a strategy across two decades of institutional filings, that is what WhaleWisdom is built for, and it is the reason to use it.

How 13F Pro differs

13F Pro is not primarily a filings archive. Every one of 2,800+ companies carries a quality score derived from 32 signals built on SEC XBRL fundamentals — revenue, margins, cash flow, balance sheet — alongside the 13F data. WhaleWisdom tells you what institutions hold; 13F Pro also scores the underlying business. The two answer different questions.

13F Pro pricing

Common questions

Is 13F Pro cheaper than WhaleWisdom?

Yes, on the figures published on each site as of 7 September 2026. 13F Pro Pro is $9.99/mo; WhaleWisdom Standard is $90 per quarter, which works out to about $30/mo. Both offer a free tier. Check both pricing pages before deciding — prices change.

Does 13F Pro have 13F data going back to 2001?

No. WhaleWisdom's paid tiers carry 13F history back to 2001 and 13F Pro does not match that depth. If a long historical archive is what you need, WhaleWisdom is the stronger tool for it.

What does 13F Pro do that WhaleWisdom does not?

13F Pro scores the underlying companies, not only the filings. Each of 2,800+ companies gets a quality score built from 32 signals over SEC XBRL fundamentals, plus AI-written analysis and a daily AI research debate. WhaleWisdom is focused on the institutional holdings data itself.
