Normally Product Hunt, here on Hacker News, Reddit, Twitter. Sometimes I publish to some specific directories. Marketing-wise, I'm not doing anything apart from launching more side-projects related to the main ones. What would you suggest me to do? I've tried a bit of ads in the past. I'm more into products, so, not easy for me to know what to do without spending money. My revenue comes mainly from AnyToSpeech, which is tiny but allows me to test and launch new products.
