The people behind adaptive personalisation.
We're a team of engineers, designers, and growth practitioners who spent years building and scaling B2B SaaS products. Mister Chameleon is what happens when that experience meets a problem we couldn't stop thinking about. Based in Amsterdam, working remotely across Europe.

Started by people who felt the problem first.
Lucas came from growth - he'd spent years driving traffic to websites that couldn't adapt to the visitors arriving. Noa came from infrastructure - she'd built real-time data pipelines and kept asking why the outputs weren't being used. They met at a B2B SaaS scale-up in Amsterdam and the idea started there. The thesis was simple: the hard part of personalisation isn't the logic - it's making the whole system accessible to marketing teams without requiring a developer for every change. That's what Mister Chameleon is built around.
Meet everyone
No layers, no org chart complexity. This is the whole team.

Co-founder & CEO
Former VP Growth at a B2B SaaS scale-up. Built and broke enough generic websites to know there had to be a better way.

Edge computing specialist. Previously built real-time data pipelines at scale. Obsessed with sub-50ms decision latency.

Ines de Graaf
Design Lead

We build in the open, move fast, and own our mistakes.
There are no shadow roadmaps or top-down feature mandates. The team that builds a feature is the team that designed it, tested it, and shipped it. That means slower consensus sometimes - and much better decisions overall. We write in public (our changelog is detailed and honest), we document decisions in Notion, and we ship to production multiple times a day. Every engineer has access to production data. Every designer talks to customers.
How we work
Remote-first, not remote-only
Everyone works from wherever they're most productive. We meet in Amsterdam three or four times a year for planning and for the things that genuinely need a whiteboard.
Small team, real ownership
We move fast because every person owns a significant part of the product. You won't spend your days in approval chains or waiting for sign-off.
Honest over polite
We give direct feedback, assume good intent, and say what we actually think. We expect the same in return. No performance reviews full of vague positives.
Learning budget - no strings
Every team member gets €1,500 per year for books, courses, conferences, or whatever makes them sharper. No approval process, no justification required.
No meeting Wednesdays
The full day is protected for deep work. Slack goes quiet, calendars stay clear. We take this one seriously.
Ship it, then improve it
We'd rather have something real in front of customers than perfect in a branch. We iterate fast, we break things occasionally, and we fix them faster.
In their own words
I've shipped more meaningful product in 18 months here than I did in four years at my previous job. The ownership is real, not just a line in the job description.
Sofia Martins
Lead Engineer · Mister ChameleonThe customer feedback loop is tighter than anywhere I've worked. I talk to customers every week and what they say actually changes what we build. That's rare.
Daan Visser
Head of Product · Mister ChameleonRemote-first sounds like a cliche until you've actually worked somewhere that means it. No commute, no open-plan noise, and I can still fly to Amsterdam when I want to be in the room.

Amsterdam headquarters. European team.
Our office is on the Keizersgracht in Amsterdam - a short walk from Leidseplein. When the team is in town we use it for planning sessions, onboarding new starters, and the occasional Friday afternoon that runs long. Most of the time you'll reach us on Slack, in a Notion doc, or in a 30-minute Zoom call that ends on time.
We're growing. Come help us build.
We hire for character and capability - not just a matching list of keywords on a CV. The things we value most: clear thinking, honest communication, and a genuine interest in the problem we're solving. We look for people who've done the work, not just managed it. Who write clearly, ask good questions, and can disagree without making it personal. Below are our open roles. If nothing fits but you think you'd contribute something the team is missing, send a note anyway.
