Viral Marketing

What: an experiment to explore if we can get our existing users and customers to refer new users and customers.

Important note: only works if you have a good product. People will not risk their reputation sharing a product they don't like, whatever the incentive.

Lean experiment

  • Email your existing (happy customers)
  • Ask them to refer someone 
  • Reach out manually to each referral
  • Track new sign ups
  • Reward referrers with a small gift
  • Track the effectiveness of the scheme
  • Look to automate


There are lots of SAAS [software as a service tools] that are available to to build refer-a-friend functionality. Here are some choices.
