Built by one person,
for everyone.

OpenCongress is built and maintained by Pierre Pariente Dimitrov — born and raised in France, but living in the United States for over a decade, across San Francisco, Los Angeles, and New York.

Pierre is a product designer, UX designer, and engineer with fifteen years of experience building digital products across organizations of all sizes — from early-stage startups to large enterprises. 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. In both the U.S. and France, 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 dual-country focus isn't arbitrary. As someone who's lived between France and the United States for over a decade, Pierre has experienced firsthand how hard it is to stay informed about the legislative process in either country — let alone both. OpenCongress brings the same approach to both: clear, nonpartisan, AI-powered tools that make it easy to understand what's happening in Congress, the Assemblée Nationale, and the Sénat.

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.
