Back in 2011, I was asked to join a team to create an app that could help people connect based on their interests rather than on their friendship network. We were funded by Solid ventures who invested 1m Euro and we explored many, many i different angles and possibilities. In the end we focused on helping protestors congregate as the project coincided with the #occupy movement in the USA. It worked in the sense of functionality but we never generated enough value to make a subscription model viable.
I renamed (Protest4), rebranded the app and helped it gain international press coverage.
Still a fun time was had by all! https://paperjam.lu/article/news-protest4-une-application-pour-manifestants
