One of the fastest ways to validate a new SaaS is to rent someone else's audience. Find a YouTube creator in your niche, pay them for an integration or offer an affiliate cut, and direct their traffic to your landing page.
But most founders who try this hit a wall. They find a creator with 500,000 subscribers, pay $1,000 for a shoutout, and get exactly zero sales.
They assume the product is bad. It isn't. The problem is the influencer.
A creator with a million subscribers and a dead audience will yield zero clicks. If you are using a creator to validate your idea, picking the wrong one gives you a false Kill signal. You need a mathematical filter before you reach out to anyone.
Loic, a serial founder from France who scaled apps including Minia and Drop Magic to over $35,000/month, relies heavily on YouTube creators for distribution — sometimes even bringing them on as co-founders. But Loic does not care about subscriber counts. Before he sends a single outreach message, he runs every creator through a 3-step mathematical audit. If they fail, he ignores them.
Here is the exact framework.
Filter 1: The 10% View Rule
The biggest lie on YouTube and TikTok is the subscriber count. A creator might have had one viral video five years ago that pulled in 100,000 subscribers, but today nobody watches them.
The test: Look at their last 5–10 videos. Divide the average view count by their total subscriber count.
- 100,000 subscribers averaging 2,000 views per video = 2% engagement. The audience is dead.
- 100,000 subscribers averaging 12,000 views per video = 12% engagement. The audience is active.
Loic requires a minimum of 10%. If they have 100k subscribers, they must consistently clear 10k views. Anything below that means the audience stopped caring — and they will not click your link either.
Filter 2: The 100-Comment Minimum
Views can be bought. Views can also be passive — people who left autoplay running while making coffee.
You don't want passive viewers. You want an audience that takes action, because clicking a SaaS link requires action.
The test: Open the comment section on their recent videos. Loic looks for a hard minimum of 100 real comments per video. Not just count — read them.
Are the comments spam bots typing "Great video!" or are they real people asking the creator detailed follow-up questions? High comment quality signals genuine trust. And trust is what converts.
Filter 3: The Repeat Sponsor Test
This is the definitive filter. Creators can inflate views and seed comments, but they cannot fake ROI for a paying sponsor.
Brands track every click and every sale. If a brand sponsors a creator and loses money, they don't come back. If a brand sponsors a creator and makes money, they buy another integration. Repeat business is proof of performance.
The test: Look at the creator's last 6 months of content. Has any specific brand — Surfshark, Notion, BetterHelp, whoever — sponsored them at least 3 times?
If you see the same sponsor appearing repeatedly, that is direct evidence that this creator's audience opens their wallets. No brand repeats a losing investment.
Why This Matters for Validation
Most founders who run an influencer validation test and get zero results conclude their idea has no market.
That conclusion is often wrong. What actually happened is that they paid for a dead audience and got a dead result. The signal was noise.
The 3-filter audit means that when you send traffic to your validation landing page, you know that traffic is real. If you get a 5% click-through rate from a legitimate creator's audience, that is a meaningful signal. If you get 0% from a dead one, you've learned nothing about your idea — only about the creator.
Garbage in, garbage out. The audit removes the garbage.
The Protocol: Before You Reach Out
- Build a list of 10 creators who make content for your specific target user
- Apply the 10% rule — divide average views by subscriber count, cut anyone below 10%
- Check the comments — minimum 100 real comments per video, with genuine engagement
- Find the repeat sponsors — look for the same brand appearing 3+ times in their recent history
- Pitch the survivors — for the 1 or 2 creators who pass all three filters, send a performance offer: "I built a tool for your audience. I'll give you 50% of revenue if we launch it together."
One creator with a real audience is worth more than fifty with inflated subscriber counts. Filter hard. Partner with the ones who can actually move the needle.
