Sponsor
a day
Pick a day of the challenge and it wears your artwork: full-bleed, behind the photo, for that day only — and for good, because these pages do not come down. Software or supplements, it is the same deal: most people reading this are building something too. From €150 a day.

- Step 1Pick your days
Any day from 2026-09-13 to 2026-12-12, including days that have already happened — day 1 is the page everyone lands on. One sponsor per day, no sharing.
- Step 2Send your artwork
After checkout you get a private link to upload it, set where the label points and choose which day gets which skin. I review every one by hand, usually within 24 hours.
- Step 3It stays up
Your skin sits behind that day’s photo, with a “Sponsored” label linking to you, plus a chip on the day page and a line on the sponsor wall.
What a sponsored day looks like
Twelve concepts for two made-up brands, to show the range. The photo, the controls and the “Sponsored” label are always the site’s; everything around them is yours.

Artwork
Desktop — required
2400 × 1140 px · 2.11:1
The one that matters. On a wide screen the photo sits in the middle and your artwork has the space either side — that is where the concepts put the line and the product.
Minimum 1200 × 570. Shape within ±10%.
Download the template
Mobile — optional
1170 × 1260 px · 0.93:1
On a phone the photo covers most of the stage, so this one reads as a frame. Skip it and the desktop art is used, cropped to fit — recommended, not required.
Minimum 585 × 630. Shape within ±10%.
Download the template
- · JPG, PNG or WebP, up to 6 MB each.
- · No SVG. It is a document rather than an image, and this one ends up on a page other people load.
- · Keep your logo and copy out of the marked areas: the photo sits in the middle, our controls bottom-left, the hint bottom-right, and the “Sponsored” label top-left.
- · The templates above have every one of those areas drawn on them.

I don’t take gambling, alcohol, miracle supplements or crypto. Every sponsored day is labelled as sponsored — that label is drawn by the site, not by you, and it is not negotiable.
