I'm a solo founder, and like many of you, I noticed a painful lack of transparency in the Creator Economy: Micro-influencers don't know what to charge, so they often accept rates 50% below market value.
I spent the last few weeks building an MVP called RateUp - Influencer Calculator.
It’s a free, simple calculator that instantly gives a creator a fair market price for their content (Reels, Stories, Feed) in USD or BRL. The price is calculated based on their Engagement Rate (ER) and niche (e.g., Finance/Tech generally charges more than Lifestyle).

I'm an indie developer, not a full-time marketer, so my biggest challenge is validating the core economics and the monetization. I need your brutal feedback on two things:
Pricing Logic: Use the tool. Is the final suggested rate believable and fair? Do I need to incorporate more complex factors? Is the math flawed for very small creators?
Monetization Funnel: My current plan is to monetize by selling a "Premium Rate Card PDF" (delivered via email capture). Is this a good first monetization step, or should I be focusing on something else, like paid "Influencer Contract Templates"?
I’m committed to sharing all my progress (and failures!) here. Any feedback—on the logic, the product, or the name—is highly appreciated.

Thanks for taking a look!
