Elia Mörling discusses how they smashed their Indiegogo campaign in 2 days for their smartwatch with wireless data storage called ReVault. With only 16 bootstrappers from Sweden and a minimal budget, they used growth hacking techniques like targeting specific tribes through experiments with messages, channels, and a 3D design challenge. They focused on acquisition, activation, retention, referral, and revenue using techniques like segmented emails, contests, newsletters, and community deals. This resulted in $60k raised in 2 days with 400 backers from 45 countries and 25% of backers from their own community. Key learnings included the importance of tribe marketing, referral campaigns, hitting funding targets early, and testing everything.
