Dropbox chief to join elite ranks of idea-to-IPO founders

When Drew Houston played computer games like “StarCraft” in high school, he made some changes so the games ran more smoothly on his friends’ computers.

“He created this one little application, and it would basically display everybody’s shared files, and then if you clicked on a file, it would go ahead and ask everyone else on the network if they wanted to download it as well,” said Andrew Croswell, who went to high school with Houston in Massachusetts.

Houston, 35, has since taken a version of that same concept and turned it into Dropbox, an online file storage and collaboration company that has grown rapidly since its founding in 2007.
