The problem I was trying to solve
Running paid ads is expensive. Most indie hackers and small
startups can't afford $5k/month on Facebook or Google ads.
So I started thinking — what if we just helped each other?
What I built
A platform where:
- You post about other people's services on your SNS
- You earn points for every post
- Others use their points to post about YOUR service
AI automatically writes 17 promotional posts for every
channel — Instagram, YouTube, TikTok, X, Facebook,
Naver Blog, Threads. Images auto-resized for every platform.
How it actually works
- Register your service URL
- Browse missions — other services waiting to be promoted
- Post on your SNS → earn points
- Your points attract others to promote you back
What I've learned so far
Getting the first users is hard. Really hard.
Cold emails get ~30% open rate but low conversion.
The concept of "mutual marketing" is new to most people.
Trust is the biggest barrier — "will anyone actually promote me?"
What's next
Still looking for the first 10 real users to test this.
Would love your feedback:
- Does this concept make sense to you?
- What would stop you from trying it?
- Would you use this for your own project?
