Yes, Product Hunt can be a great platform to launch a challenge and create awareness. Many have successfully used it for similar purposes. Consider leveraging the engaged community and visibility it offers for maximum impact.
@Daniel I can tell you from our own experience we run our platform to provide a revenue share to developers and web designers and have gotten very little engagement on PH.
@blueowl - I just followed you on here and sent over a LinkedIn connection. I am curious - did you run a challenge to promote the product to the dev community and got very little engagement? or simply launched and got little engagement from the community that way?
