Who does what
You bring the credential and the audience. We handle the product, the store and every buyer.
About 5 to 7 hours around launch, then a few minutes a month.
Everything it takes to sell a product, from first draft to every payout.
Where the money goes on one $79 guide
Your 60% is figured on the full sale price, before any fees. Example only; prices are set with you.
How it works
What your audience asks you most, and whether a product fits your channel.
Content, design, sales page, store and checkout, in your voice.
You check every question, answer or session for accuracy. Nothing goes live until you approve it.
Link in bio and 4 posts or stories in the first month. You're paid from the first sale.
Terms
These are the starting terms we put in writing before anything launches.
Who we work with
Your audience is working toward something specific: a license, a checkride, a first race. The content has to hold up in front of them, so your credential and your review are part of every product.
Who you'd work with
Blake spent years teaching skydiving students as a certified instructor, and he builds the study guides his colleagues use to prepare for certification exams. He started Primer & Proof to give creators a finished product without the production work.
He's your one point of contact from the first call to every payout.
FAQ
From our 40% of sales. If nothing sells, we don't get paid, which is why we only build products we expect to sell.
You review every page before launch, and you or a buyer can flag an error at any time after. We fix it within 7 days and send every buyer the corrected copy.
No. Mention it in the videos and stories you already make and keep the link in your bio.
One free payout account, so the store can pay you. It takes about 10 minutes, and it is the only account you open.
We set it together, based on what your audience already pays for similar products.
We check for conflicts on the first call. Nothing in our terms limits your other deals.
Not for you. You can keep doing brand deals and selling your own things. We just won't sell this product without you.
Yes. Because you earn a share of sales, your posts say so clearly, as the FTC requires. We give you the wording.
