NationGraph is an AI-native sales intelligence platform that helps vendors predict and win public-sector contracts in state, local, and education markets. It uses AI to index and analyze data from over 100,000 government entities, surfacing buying signals from contracts, meeting minutes, budgets, and purchase orders. The platform provides verified contacts, competitive intelligence, and account insights to enable earlier engagement before RFPs are released. Co-founded by CEO Kimia Hamidi, it raised $18 million in Series A funding in February 2026 led by Menlo Ventures.
