1. 牽手慈善

????科技公司Atlassian明白，要想吸引小公司使用它的新款軟件,，必須提供比免費試用更有意思的東西。于是，公司以10美元的價格將產(chǎn)品提供給公司使用,，同時承諾將把銷售所得捐贈給全球文化慈善活動，結果引起Facebook與Twitter用戶的廣泛傳播,。這家公司自從2009年推出這一措施以來已經(jīng)為慈善機構閱讀空間（Room to Read）總計募集了150萬美元,。而在最初購買10美元軟件套裝的客戶群中，公司產(chǎn)品的銷售額增加到了約800萬美元,。

1. Find new ways to do 'free'

????To attract small businesses to its new software, tech company Atlassian knew it had to offer something more intriguing than a free trial. Instead it gave very small firms use of the product for $10 and promised to donate that money to a global literacy charity -- inspiring many mentions on Facebook and Twitter. Since making the offer in 2009, it has raised $1.5 million for the charity, Room to Read. And it's sold about $8 million in products to customers trading up from the $10 package.
