Quorum vs OpenInsider
OpenInsider already proved Form 4 data isn’t scarce. Quorum sells ranked convergence — not another free Form 4 dump.
Where they are stronger
Where OpenInsider is better
OpenInsider is the stronger fit for free, server-HTML Form 4 tables, cluster buys/sells, and a no-account screener. If you only need raw insider filings in the open, OpenInsider remains the reference.
Quorum
What Quorum does differently
We do not claim exclusive Form 4 access. Quorum adds Congress STOCK Act filings + fundamentals into a ranked conviction score, with product surfaces for following that signal. Raw Form 4 alone is not our moat.

Honest close
Use OpenInsider for free Form 4 browsing. Use Quorum when the question is convergence and ranking — not “do you have Form 4s?” Research, not advice.
We do not claim to replace OpenInsider for every workflow. Use this page to decide whether ranked disclosure convergence is the job you need.
