The one number
You sell $100. Where does it actually go?
Revenue went up and your bank account did not. This is where it went.
Keep Rate is the share of gross revenue that survives advertising, Amazon fees, returns and cost of goods, and lands as profit.

Our brands, by day 90
| Line item | Most brands | By day 90 |
|---|---|---|
| Returns and promos | -10.00 | -8.00 |
| Amazon fees | -25.00 | -23.80 |
| Ad spend | -28.00 | -12.00 |

| You keep | $9.00 | $29.50 |
Cost of goods does not move. Wasted ad spend and unclaimed fees do.
That gap is your money. We will show you yours.
Blended hides everything. One product at 45%, another at minus 6%.
Know how much you keep. Keep more.
Your team
You are hiring two things.
One operator who owns your number. One system that never clocks off.

Questions
Before you ask.
Is Revlyn an agency or a software product?
- An agency, running on our own software. You hire an operator and get a login to the same screen they work in.
How is Keep Rate calculated?
- Contribution profit divided by gross revenue. Everything you control, nothing you do not.
Do I have to hand over my cost of goods?
- No. Your Amazon Keep Rate comes from the APIs alone. Adding cost sharpens it later.
What size brand is this for?
- From about $30k a month and up. Most of our brands sit between $100k and $500k a month, where the founder is still the bottleneck.
Will my ad spend go down?
- In the fix phase, usually. In the scale phase it goes up on purpose, because it finally pays.
What does it cost?
- A 60 to 90 day pilot, then a retainer plus a percentage of managed ad spend. Retainers run $2,500 to $8,000.
Not selling on Amazon yet?
BrandEngine is the other half of the business: research, sourcing, IP and launch, run to the point where a product is live and holding a Keep Rate worth scaling.
Find out what you keep.
Give us access. Day one you get your Keep Rate, what is draining it and what we would fix first, then we spend the next thirty days fixing it on one SKU.
Teardown in 48 hours, thirty days of work after it. Free. Yours either way.
20 brands a quarter. 10 to 15 teardowns a week.
