Selling FirstRevenue, an IOS app that helps beginners start earning money online. Users get a personalised roadmap and daily action plans based on their goals, budget and experience. Growth is from mostly automated Titkok slideshows, while some experimentation with paid ads has been done. There is a big opportunity to expand to instagram and run more paid ads as all revenue is mostly passive now. Big upside for a buyer with an audience or paid ads network and the app could easily get past $10k/m
