Our Story

From Mission-Critical Roots to AI Leadership

Founded in 2021 in Washington, D.C., Capitol helps leading organizations—such as Politico and Dow Jones—unlock deep insights from their unstructured data, driving significant revenue and strategic opportunities.

Our founders first collaborated to address complex federal challenges during the COVID-19 pandemic, creating an AI platform to predict and mitigate critical supply chain disruptions. This experience demonstrated the transformative power of combining advanced technology and human-centered design, laying the foundation for Capitol AI.

After launching, Capitol was selected for Y Combinator’s Summer 2024 cohort and quickly emerged as its revenue leader, successfully securing Series A funding led by Together Fund in 2025. We’ve invested tens of thousands of engineering hours to deliver a sophisticated AI solution that's both highly effective and significantly more efficient than building in-house, both in terms of time and budget.
