An AI tool is a new kind of digital product that you can sell to your clients. It has your unique method baked in and gets them results on autopilot, without needing you in the room. You build it once. It sells while you sleep.
Sound familiar?
Building & launching a digital product used to eat up a full month of your life.
Now it takes less than 1 day and makes money by the end of the week.
Launching something new meant locking yourself up for WEEKS.
Outline, record, edit, design, write, set up, ad. Weeks before the first sale.
Your Notes app is stacked with ideas. Not one of them is live yet.
Half-built ideas stacked in your Notes app, none of them ever go live.
You launched. Posted about it twice. Made 4 sales. Then nothing.
Your loyal followers bought, cold traffic clicked away, then it went quiet.
Three months in, you check the market. Someone else already built it.
By the time yours was ready, someone else had launched it and the trend had shifted.
For who want to get paid to exist selling a new type of digital product: AI tools.
No more months of outlining a course your clients may never finish. Your AI tool is built in a day, does the work for them, and is 10x easier to sell.

Let's address the obvious
You might be wondering if this works for you, if…
The only reason selling AI tools felt out of reach was that no one had built the thing that builds them for you. That is what SellbySunday™ is.
Who built this
Hey, I'm Thessa.
I run REVENU, a brand built on making income radically accessible for ambitious women. I got tired of watching coaches and creators spend months building products that didn't convert, or worse, never launching at all.
SellbySunday™ is the toolkit I wish existed when I started. It compresses the entire process, validation, copy, ads, into one afternoon. Because the idea is only as powerful as the system that gets it in front of buyers.
Everything inside
Everything that used to take months. Done in one afternoon.

Three months from now
Nothing changes unless something changes.
In three months, the audience is still there. The idea is still in a notes app. Someone else in your niche has already launched their AI tool, priced it at €27, and sold it 200 times. You are ready. The method is the only thing missing.
No catch
Why is this only €47?
Low ticket is the whole point. We want more women in the room, not fewer.
That is not urgency marketing. That is the actual plan.
