31. 凱蒂婭?比徹姆和海利?巴爾納

?? 年齡：30，30

?? 職務：聯合創始人和聯合CEO

?? 任職公司：化妝品公司Birchbox

????2010年，哈佛大學商學院（Harvard Business School）畢業生巴爾納和比徹姆于創建了Birchbox，每月為女性用戶提供四到五種價格為10美元的化妝品樣品。這家初創公司使訂購成為流行趨勢，但是它本身并沒有進行這樣的分類。每月的化妝品套裝為一小份新產品，這促使一半以上的訂購者在Birchbox網站上購買全套產品。截至目前，Birchbox已獲得1,190萬美元融資，并于2012年4月發布了男士系列產品（每月樣品價格為20美元）。同年9月，Birchbox并購了巴黎的JolieBox，輕而易舉地把業務擴展到法國、西班牙和英國市場，用戶數量更是達到40萬。

31. Katia Beauchamp & Hayley Barna

?? Age:30, 30

?? Title:Co-Founders and Co-CEOs

?? Company:Birchbox

????Founded in 2010 by Harvard Business School grads Barna and Beauchamp, Birchbox providers its female users with four to five beauty samples for $10 a month. The startup popularized the subscription box trend, but don't categorize it as such. The monthly packages enable bite-size discoveries, leading more than half of all subscribers to purchase full size products on their website. Birchbox has raised $11.9 million to date and launched its men's line (with a higher price point of $20 per month) in April 2012. It then acquired Parisian JolieBox the following September, allowing easy expansion into France, Spain and the UK, growing its user-base upwards of 400,000.
