Heatmap Shows 3,400 Venture Capital Firms Open to Cold Emails

A developer posted a Show HN project that maps venture capital firms. The heatmap displays roughly 3,400 firms across multiple regions. Each firm is marked as open to receiving cold email outreach. Data was compiled from publicly available contact information. The visual tool uses color gradients to indicate openness levels. Users can hover over points to see firm names and basic details. The creator hopes the map will help entrepreneurs target investors more efficiently. The project is hosted on a public site for anyone to explore.
