initiative.sh[0], a web-based text interface for creative D&D play. After a promising response on HN[1], I had hoped that I might be able to monetize the project, but traffic has since crashed to almost nothing. I would say that after six months of full-time development it is about halfway to being complete as a freemium product, so instead I've opted to open-source it.[2]
It turns out that the challenge with launching a freemium product is that you need something that's both useful as a free tool while also having a compelling value-add for paid users. That's a lot for one person to build. I don't think I'll be aiming for that monetization strategy with future projects.
I have to confess that I'm (barely) missing the qualifying income bracket - some kind soul is supporting me for $5/mo on buymeacoffee.[3]
