We measure what the internet says about you. Then we change it.
Zalm Partners is a Web Intelligence agency in Rotterdam. We measure what search engines and AI models say about a company, decide what needs to change, do the work and check what each change delivered.
50+ leading companies work with us
What we do
Anyone who wants to know something about your company increasingly asks an AI. The answer they get is assembled from whatever can be found about you online: your own site, trade media, directories, reviews and what your competitors say about themselves. That picture is often wrong, incomplete or simply empty. And almost nobody knows what it looks like.
We measure that picture, independently and repeatedly, per model and per stage of the customer journey. Then we decide what needs to change, do the work with whichever method it takes, and measure whether each change made a difference. That is Web Intelligence, and it is all we do.
Not an opinion about your visibility. A measurement.
How we work
- 01
Insight
A scoped first measurement: what your ideal customer sees right now, in search engines and in AI Search.
- 02
Strategy
The playing field mapped out, and for each bottleneck what needs to change, in what order, and how we will measure it.
- 03
Execution
The work itself, with the method the bottleneck calls for: from content and PR to technical work and conversion.
- 04
Verification
Measuring each change against the baseline to see whether it made a difference. What works stays; what does not goes back to Strategy.
Why it works
Measured independently
We measure with our own tooling, not with what a platform reports about itself. Every claim on this site can be checked the same way.
Everything in-house
Developers, designers and strategists at one table. Whatever the measurement surfaces, we can build, write and publish ourselves.
Entrepreneurs ourselves
Alongside client work we build our own ventures. We make the mistakes on our own platforms first, so we spot the problems others miss.
The people behind it
Zalm Partners was founded in 2024 by Just Goossens and Dries Dederen, who had been building websites for family, friends and local businesses for years before that. Today it is a Rotterdam studio of developers, designers and strategists, and most of the very first clients are still with us.
Some of them are now number one in their market, measured across multiple AI models and only on questions that do not mention their brand name.
