TDF Ventures

TDF is a Washington DC based venture capital fund focused on the communications sector. We partner with talented entrepreneurs and seek to build competitive and innovative technology and services companies. Our focus is driven by investment themes that share several qualities: large and important problems in communications, an ability to add value through management’s investing and operational experience, and the Fund’s location and relationships in Washington DC.

Designed to create a long term and measureable impact, TDF Foundation is a platform to extend communications related opportunities across underserved rural and urban communities.
