About OppoDB

Company

Research infrastructure, not a clipping service

OppoDB Holdings LLC DBA OppoDB, OppoDB.com started 2024 in Minnesota, USA with one goal: make opposition research a queryable system instead of a folder of PDFs.

Campaigns, committees and newsrooms were all doing the same work in parallel — pulling the same filings, rebuilding the same timelines, re-verifying the same claims. OppoDB centralizes that labor into a maintained database with citations attached to every assertion and a version history behind every page.

We built it as a platform first. The web app, the REST API and the MCP server all read the same records through the same permissions, so the answer your assistant gives is the answer your staff sees.

How we source

Standards
  • Every claim carries a citation to a primary source.
  • Corrections are versioned, never silently overwritten.
  • Opinion and analysis are labeled as such.
