New Video Course: Grow your Startup with a Referral System (like Dropbox)

:boom: I’m excited to announce my latest course is now live: Code-Free Growth-Hacking: How to build a viral referral system like DropBox. In the course we cover brand new Bubble concepts, like:

  • How to build a referral system to inspire viral sharing
  • An intro guide to the API connector :thumbsup:
  • How to connect a referral feature to an existing app or use it as a pre-launch campaign
  • How to automate sending out prizes to users, including automating sending physical items like T-shirts
  • How to connect to the Slack API to automate inviting users to a community Slack group.

A referral system like this is crucial for any startup because it automates word of mouth marketing. Less marketing work means you can focus on building your app while generating more revenue. This is the same strategy that companies like Harrys and Dropbox used to double their customer base in a matter of weeks instead of years.

PS - if you want to get early access to my new Bubble courses and other startup guides, just leave a comment below and I’ll send you a DM.
