Built by one person,
for everyone.

OpenCongress is built and maintained by Pierre Pariente Dimitrov, who is French and lives in New York.

Pierre is a product designer, UX designer, and engineer. His career has been about making complex systems more accessible and more usable.

OpenCongress exists because of a simple observation: legislative data is public, but it's not accessible. The information about what elected officials are doing is technically available, but buried in interfaces that weren't designed for regular people. OpenCongress was built to change that.

The same approach powers OpenCongress's coverage of the U.S. Congress, the French Parliament, and the New York City Council: clear, nonpartisan tools that make it easy to understand what your representatives are actually doing. Three deliberately different legislatures, chosen to prove the approach travels. The European Union is next.

Pierre also created Tempso, a classical music app that provides a rich metadata layer over streaming platforms, born from the same instinct to make niche, complex information more approachable.

OpenCongress is an independent, self-funded project. No venture capital, no political affiliations, no ads. Just one person trying to make civic information work better for everyone.
