I was planning to buy some beer and invite friends to toss ideas around at the pool, except that I’m quarantined in Adelaide after a 54-hour long trip from Brazil. Then I had this idea of posting something on Facebook and calling on folks to collaborate and brainstorm business ideas.

So I simultaneously posted the following message on 4 Facebook groups (Adelaide Startups, Sydney Startups, Melbourne Startup and Brisbane Startups) on Thu Feb 18th 2021 at 10:22 pm:

Some entrepreneurs lack ideas. Creatives have plenty. Share a business idea and convince me to build it and I’ll pay you A$1,000

Unfortunately, my announcement was swiftly deleted from Brisbane Startups 😩 as soon as I posted it.

What followed was absolutely mindblowing. A total of 178 people participated, who shared 85 ideas and made 518 comments in total.

But before diving into the ideas themselves, let’s review a few figures about this experiment. First, the communities are quite different in size:

Two people shared lots of ideas:

  1. Ruben TY (Melbourne): 13 ideas
  2. Erika Veloso Wielopolska (Sydney): 6 ideas

Amazing minds Ruben and Erika! Hats off to you 🙌

But what struck me was the similar level of engagement and creativity across communities. Engagement levels were quite similar across all community (~0.4%), except for PEC (1.5%).

PEC members reacted strongly to the topic and were ~4x more active, bouncing ideas and tagging each other.

The number os comments per user averaged ~3, except in Melbourne where the topic faced strong headwinds by some community members who suspected it was a scam.

The number of ideas shared was also quite similar. The figure below is adjusted by outliers (Ruben and Erika):

Adelaide was the most creative community and Melbourne the least creative, possibly as a consequence of suspicion raised by some community members and a sizeable group of “idea holders”.

Below is a summary of the ideas shared and their creators, but first:

If you’re interested in building one of these ideas or any others, I’d love to connect with you.

NOTE: If your name is listed here and you have privacy concerns and would like me to delete it, please send me a message or leave a comment and I’ll do so.

Lessons Learned

  1. Ask for authorization in communities before posting to avoid being perceived as spam;
  2. Frame the invitation in an inviting way and avoid sounding greedy and selfish;
  3. Support communities that have been undervalued or marginalised such as the creative community or female and LGBT founders;
  4. Ask people for their permission before publishing any reference to them or their community publicly;
  5. Be clear in the invitation so that participants know what to expect to avoid doubts and suspicion.
