I want to know the answer to the following question:
When Andreessen left the company he worked for, what new company did he start?
All the background I'm provided with is that "In 1993, browser software was further innovated by Marc Andreessen with the release of Mosaic, "the world's first popular browser", which made the World Wide Web system easy to use and more accessible to the average person.". Is that enough to answer the question?
