How we work
Discovery happens in the room, with the people who will use it
Halftone Atelier starts every engagement with a week on site: we sit with your team, map the work as it really happens, and leave with a shared plan instead of a slide deck.
Your team at the table
Product, support and the people closest to customers shape the brief together, from day one.
Prototypes by Thursday
We test clickable flows with real customers inside the first week, not after a month of wireframes.
A plan you can ship in six weeks
Each workshop ends with scoped, sequenced work your engineers have already seen and estimated.
Our story
Seven years of making software people keep open all day
Halftone Atelier started as two designers sharing a desk in Lisbon and a stubborn belief: interfaces should be shaped with the people who use them every day, not handed over in a PDF. We are now eleven designers and engineers across two studios — still small on purpose, still shipping what we draw.

2019
Two people, one desk in Lisbon
Inês Carvalho and Joris van Dam leave agency life to work directly with product teams. The first client is a four-person logistics start-up.
2021
First design system in production
Our component library for Pellora ships to 140 engineers. We start writing code alongside every design we deliver.
2022
The Rotterdam studio opens
Joris moves north to open a second studio by the Maas, closer to our clients in the Netherlands and Germany.
2024
Field notes, in public
We publish our research methods and workshop kits as Field Notes. Over 9,000 practitioners now read them each month.
2026
Eleven people, sixty-four products
We turn down more work than we take on, so every project gets a senior designer and engineer from kickoff to launch.
Taking on two projects for spring
Bring us the product you are stuck on
Spend a morning in the studio with the people who would design it. You leave with a scoped plan and a first sketch, whether or not we work together.
