TCV is a global technology growth-equity investor, with equity investments ranging from $10 million to $500 million and flexibility around transaction structure.
Its approach is to maintain a concentrated portfolio and commit substantial time and capital to a selected group of companies. It remains involved as businesses expand their products and enter additional geographies.
The firm’s offices in Menlo Park, New York and London support a portfolio spanning five continents. Its financing model is suited to growth-stage technology businesses undertaking a significant expansion rather than only the first product-development round.
