2026 sponsorships

CSS Day offers you a unique opportunity for your company to get in touch with our collected CSS and design talent.

In 2024 and 2025 about 340 of them congregated at our conference, and we expect similar numbers in 2026. They're all primed for in-depth discussions about CSS and related topics. Some of them are looking for a new job, others for solutions to particular design or CSS problems.

Sponsor booths

Identifier sponsors can upgrade their package with a table or booth at the conference for €3,000 extra.

The venue allows for at most four promotional sponsor booths, three of which are currently reserved. Attendees will pass your booth on their way to refreshments, and the restricted number of booths ensures that you'll get quite a bit of exposure.

A sponsor booth at one of our conferences

Your booth gives you a fixed point where attendees can come for more information about your company or your products. Our conference prioritises quality over quantity. Typically, our sponsors have fifteen to twenty quality interactions with those attendees truly interested in their offerings.

It's up to the people in your booth to convince our attendees to work for you, your clients, or to use your software. We strongly recommend that the people in your booth are front-end developers or designers themselves, because they know what makes our audience tick.

Swag

We don't hand out any goodie bags or swag ourselves, but our registration tables, or other tables at the venue, are big enough to share out stickers, t-shirts, coffee mugs or the like.

Interested?

Please contact us if you're interested in one of these packages.
