Dan Burstein is not your typical venture capitalist. He started as a journalist and has written 14 books on everything from Japanese finance to what makes a great thriller. He talks to Bradley about the precarious state of venture investing, as well as his latest book, a children's story called 'The Ivy Hero: The Brave Life of Sergeant William Shemin', co-written with Sara Shemin Cass, about a relative of theirs who they refuse to let be forgotten.
