From Real Engines Of Growth Have Nothing To Do With Growth Hacking, quoting Ooga Labs co-founder Stan Chudnovsky:
The most powerfully growing products do three things at once:
1.They make you look smart to the people you invite.
2. They give real value to you when the people you invite join.
3. They give real value to the people you’ve invited once they sign up.
Notes: (1) Why does the recommendation need to make you look smart? Isn’t it enough that the recommended product gives real value to you and to the person you recommend it to? (2) Funny how statements of what should be obvious are nonetheless so enlightening. Cf. The 3 conditions of a great fremium business. (3) Thank you Guy Cohen for the link.
