I built a tool that helps founders grow on Reddit, X, and LinkedIn

Hacker News

Hey HN,I'm Arthur, solo founder here. After struggling to get consistent traffic for my own startup, I realized I was spending more time guessing how to market than actually building. So I made something small but useful. MediaFast is a simple tool that gives you daily marketing roadmaps for Reddit, X, and LinkedIn. No fluff, just concrete tasks that help you get seen. It covers: – Where and how to post on Reddit without getting banned – What to tweet to get engagement as a SaaS founder – How to grow LinkedIn with cold DMs and soft content Since launching, I’ve gotten 15k+ visitors and $5.7k in revenue, just from using my own tool and posting on socials. Now I’m trying to help others do the same. Would love feedback, especially on how to make the product more useful for solo devs and indie hackers. Thanks for reading!
