Alexandria, Virginia venture-capital firm co-founded by Mark Warner
Columbia Capital is an Alexandria, Virginia-based venture-capital firm founded in 1989 that invests in technology, telecommunications and digital-infrastructure companies. Mark Warner co-founded the firm and served as managing director, and the telecom and venture ventures he built there are the principal source of his personal fortune, which OpenSecrets and Forbes place above $200 million. The firm has since raised roughly $9 billion in cumulative fund commitments. [Mark Warner — Wikipedia ↗]
