Astaro makes and markets a network appliance built on Linux and a complement of open source tools to help prevent spam, viruses, and other potential Internet intrusions. When Astaro's founders launched the company in 2000, venture capital funding for open source businesses was hard to find. CEO Jan Hichert says he and his colleagues tried but failed to secure funding and had to bootstrap. After the company was proved successful, VCs proved more willing to contribute to a company built on open source.
