the web performance conference 30-31 October 2025, Amsterdam

2025 sponsorships

Sponsoring performance.now() allows you to reach performance and website optimization practitioners and decision makers in Europe’s leading technology organizations—and they might even be using your software.

The sixth performance.now() conference will take place on 30 & 31 October 2025 in Amsterdam.

Our typical attendee is technically very savvy, with experience in JavaScript, CSS, server-side languages, image optimization, devops, monitoring, and full-stack web development. Also, they have an interest in software that can inform their performance decisions, and in talking to representatives of that software.

The 2023 and 2024 editions sold out at about 340 attendees each from all over Europe—and 12.5% from even further abroad.

Booth

+€5,000

A booth allows you to have your own meeting place at the conference.

Measure or Mark sponsors can upgrade their package with a booth at the conference. This allows you to interact with the audience, for instance by demoing your software. You can expect a few high-quality conversations with attendees who are genuinely interested in your offerings.

There's a maximum of five booths, and two have meanwhile been reserved.

Measure perks

A Measure sponsorship comes with one of these exclusive perks of your choice, subject to availability.

Afterparty (Thursday reserved)

Exclusive sponsorship of the Thursday evening or Friday evening afterparty. The party will take place at the venue, and will start at the end of the conference around 18:00 and continue until about 21:00. During the afterparty your logo will be prominently visible, among other things on the beer mats (coasters).

Event wifi

Exclusive sponsorship of the conference wifi. Your company name will be the password—all attendees will actually have to type it into all of their devices.

Pre-conference meetup (reserved)

Exclusive sponsorship of the pre-conference meet-up on Wednesday evening. This is a community-based meet-up; not an event for your company. We'll facilitate you, so you can host it. Some experience with organising community-based meet-ups required.

Bespoke banners

Here, the banner is over the catering buffet. This is what you can expect when you sponsor the afterparty (Measure) or lunch (Mark).

All Measure and Mark sponsors pick a perk. We will create a bespoke banner with their logo that will be placed close to their perk.

Mark perks

A Mark sponsorship comes with one of these exclusive perks of your choice, subject to availability.

Barista (reserved)

Exclusive sponsorship of the barista on Thursday or Friday. It will be available from 08:00-16:00. This includes both coffee breaks and the lunch break.

Stroopwafelkraam (reserved)

Exclusive sponsorship of a special stand with Dutch stroopwafels available on both days from roughly 10:00-16:00.

Lunch

Exclusive sponsorship of the Thursday or Friday croissants, first coffee break, and lunch.

Swag

All sponsors can leave swag, such as stickers, pens, cups, or t-shirts, in the venue, or give it out at their booth or somewhere else. We don't have a conference bag, but our experience is that our attendees will pick up interesting swag anyway.
