最佳與最差：硅谷科技初創公司CEO評點2013

要說硅谷最出名的特點莫過于它大膽的極速創新。初創公司在這里推出有前途的創意，或以更好的方式執行已經存在的創意。今天還是斗志昂揚的模范人物，明天可能就成了守舊派。而一款產品的發布可能就會促成一個新軟件或硬件分類的誕生。

過去十二個月的科技行業有許多重要時刻，比如微軟（Microsoft）CEO史蒂夫?鮑爾默計劃辭職，再比如Twitter公司成功上市。《財富》雜志今年另辟蹊徑，邀請九位初創公司CEO用自己的話來回顧2013年的科技行業。

If Silicon Valley is known for anything, it's breakneck innovation, consequences often be damned. Startups debut promising ideas -- or execute an already existing idea better. Today's scrappy poster child becomes tomorrow's old establishment. And one product launch is enough to ignite a new software or hardware category.

The last 12 months have proven chock-full of important tech moments, whether it was news of Microsoft (MSFT) CEO Steve Ballmer's intention to step down or Twitter's (TWTR) successful IPO. For a different perspective on 2013 in tech, Fortune sought out nine startup CEOs to weigh in, in their own words.
