Meet Flo - a German solo dev who built Mon.ai, an AI-powered expense tracker. He spent a year and a half trying every distribution channel by himself. Barely made a few hundred bucks.
Then a Colombian content creator found his socials inside the app and reached out. They negotiated a deal: fixed monthly retainer + percentage of PROFITS (not revenue - that didn’t scale).
Only 3 videos a month. High quality, story-driven. That’s it.
The first video? Just a simple walkthrough. Within a week they 10x’d MRR. Within a month they were at $8K.
Then $13K. Then Apple invited them to WWDC together - that video did 1.7M views and added $5K MRR. Latest feature video pushed them past $35K.
Total growth: 10,000%.
Why it worked:
> Skin in the game. Profit share = he thinks like an owner, not a contractor
> Quality over quantity. 3 videos > 100 spammy TikToks
> Look OUTSIDE the US. The Colombian market was wide open
> Put your socials IN the app so creators can find you
Flo’s playbook for finding your own partner:
1. Align on lifestyle, tone, audience
2. Warm up the relationship (follow, comment, be real)
3. Reference a specific video in your outreach
4. Connect the dots to your product
5. Signal willingness to pay early, show them the ceiling
Takeaway: You probably don’t have a product problem. You most likely have a distribution problem.
