Marc Andreessen should need no introduction, but I’ll do one anyway. He helped code the first widely used graphical web browser, Mosaic, which as I see it makes him one of the inventors of the internet. He co-founded Netscape and various other companies. He also co-founded the venture capital firm Andreessen Horowitz (with Ben Horowitz), also known as A16Z, one of the country’s largest VC firms. Recently he has launched a media publication called Future, where he occasionally writes his thoughts.
