GrowthHackers.com is a community to learn and share about ethical online marketing techniques that drive effective, scalable and sustainable growth. Online marketing is undergoing rapid changes in response to near realtime feedback loops that reveal the effectiveness of marketing programs. Rapid testing, iteration/optimization and aggressive scaling of things that work define an effective customer acquisition approach today. While all marketers are becoming more agile, the growth hacking community is focused on extreme agility and using all available levers to drive sustainable growth. The term “growth hacking” was coined by Sean Ellis in 2010 and was initially intended for startups to define a high impact growth role. Given the growth pressures on all marketing organizations, accomplished marketers in bigger companies have also seen the importance of growth hacking. The purpose of GrowthHackers.com is to give experiment driven marketers a place to share and discuss what truly matters in driving sustainable customer acquisition growth across all key growth levers. Discussions are often prompted through popular marketing articles and questions posted by the community. In addition to our direct experience at companies like Dropbox, Eventbrite, and LogMeIn, the GrowthHackers.com team has studied the growth engines of several leading companies, and generally find that word of mouth is a major factor. But we’ve also found that optimization around delivering the must-have experience for a great product is critical for accelerating word of mouth and retaining customers. Of course, there are many other growth drivers beyond word of mouth such as platform integrations, viral growth and even paid marketing channels. The GrowthHackers.com community explores all of them. The community is strongly against unethical growth tactics such as spam (email, invite, etc), which tend to be unsustainable anyway.
