the web performance conference 19-20 November 2026, Amsterdam

2026 sponsorships

The seventh performance.now() conference will take place on 19th & 20th of November 2026 in Amsterdam.

performance.now() is a single track conference covering today’s most important web performance insights. It is the perfect place to reach web performance professionals at the exact moment they're most open to discussing their approach and toolkit.

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.

We expect about 300-320 attendees from all over Europe—and 12.5% from even further abroad.

Booth (all reserved)

+€6,000

Resource or Measure sponsors can upgrade their package with a booth at the conference. They allow you to interact with the audience, for instance by demoing your software or introducing attendees to your company.

Quality over quantity — you can expect high-quality conversations with attendees who are genuinely interested in your offerings, but you won't get hundreds of email addresses from people that are barely aware of your company's existence.

There's a maximum of five booths, and all have been reserved so far — though in some cases the reservation isn't yet final.

Resource perk

As the Resource sponsor, your logo will grace the live stream and conference videos for all eternity. You will get relatively little attention during the conference, though.

Measure perks

A Measure sponsorship comes with one of these exclusive perks of your choice:

Afterparty (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 (reserved)

Exclusive sponsorship of the conference wifi. Your company name will be the password — all attendees will have to type it into all of their on-average 1.5 devices.

Barista (reserved)

Exclusive sponsorship of the barista. People love their coffee.

Stroopwafelkraam (reserved)

Exclusive sponsorship of a special stand with stroopwafels [STROHP-wahfels]. This sweet Dutch delight goes over very will with an audience in need of a sugar fix.

Bespoke banners

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.

Lunch

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

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 concentrate on the content. Some experience with organising community-based meet-ups required.

Post-conference meetup (reserved)

Exclusive sponsorship of the pre-conference meet-up on Saturday morning and afternoon. Some experience with organising meet-ups required.

Remember that by Saturday the audience is tired and mostly wants to chat in a friendly environment.

Captioning

Captioning helps attendees with hearing disabilities — and any attendee who dozes off for a moment and misses a few words.

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.
