    In 1989 John Hummer and Ann Winblad formed Hummer Winblad Venture Partners as the first venture capital fund focused exclusively on software and Internet companies. The firm makes investments from under $100,000 to over $5 million, generally preferring early stage investments. However, Hummer is willing to consider companies at any stage. The firm has invested in companies in desktop software, embedded systems, client-server, distributed network computing, internet, and software as a service.
