Most indie hackers and small <br> startups can't afford $5k/month on Facebook or Google ads.</p> <p>So I started thinking — what if we just helped each other?</p> <h2> What I built </h2> <p>A platform where:</p> <ul> <li>You post about other people's services on your SNS</li> <li>You earn points for every post</li> <li>Others use their points to post about YOUR service</li> </ul> <p>AI automatically writes 17 promotional posts for every <br> channel — Instagram, YouTube, TikTok, X, Facebook, <br> Naver Blog, Threads. Images auto-resized for every platform.</p> <h2> How it actually works </h2> <ol> <li>Register your service URL</li> <li>Browse missions — other services waiting to be promoted</li> <li>Post on your SNS → earn points</li> <li>Your points attract others to promote you back</li> </ol> <h2> What I've learned so far </h2> <p>Getting the first users is hard. Really hard.</p> <p>Cold emails get ~30% open rate but low conversion.<br> The concept of "mutual marketing" is new to most people.<br> Trust is the biggest barrier — "will anyone actually promote me?"</p> <h2> What's next </h2> <p>Still looking for the first 10 real users to test this.</p> <p>Would love your feedback:</p> <ul> <li>Does this concept make sense to you?</li> <li>What would stop you from trying it?</li> <li>Would you use this for your own project?</li> </ul> <p>Live at mafull.com — free to start.</p> marketing showdev socialmedia startup jerry hoo Mon, 18 May 2026 21:11:41 +0000 https://dev.to/jerry_hoo_df69638072c5ced/i-built-a-free-mutual-sns-marketing-platform-ai-writes-your-posts-real-people-share-them-26gg https://dev.to/jerry_hoo_df69638072c5ced/i-built-a-free-mutual-sns-marketing-platform-ai-writes-your-posts-real-people-share-them-26gg <h2> The problem </h2> <p>I was tired of paying for ads that nobody clicked. <br> Most small businesses and startups can't afford agencies either.</p> <h2> What I built </h2> <p>Mafull — a mutual SNS marketing community where members <br> promote each other's services for free.</p> <h2> How it works </h2> <ol> <li>Register your service URL</li> <li>AI automatically writes 17 promotional posts for every SNS channel (Instagram, YouTube, TikTok, X, Facebook, Naver Blog, Threads)</li> <li>Images are auto-resized for each platform</li> <li>Complete missions by posting about other services → earn points</li> <li>Points attract others to promote your service in return</li> </ol> <h2> The idea </h2> <p>It's basically "you scratch my back, I'll scratch yours" — <br> but for SNS marketing.</p> <p>No ad budget. No agency. Real people, real posts.</p> <h2> Current status </h2> <p>Just launched. Still early stage.</p> <p>Would love feedback from the dev community!</p> <p>👉 mafull.com</p> <h2> Questions for you </h2> <ul> <li>Would you use something like this for your own project?</li> <li>What features would make this more useful?</li> </ul>
