Data and analytics consultancy, Amsterdam

Trust your data.

Your reports, your bidding strategies and your AI are never better than the data that reaches them.

We design, build and run the data foundation underneath: how data is collected, how it is processed, and how it stays compliant. And we keep it running after go-live.

A selection of our clients

Which question brings you here?

 

Nobody wakes up wanting a data layer. They want an answer they can act on.

These are the questions organisations bring to us most. When the numbers don't add up, the cause is almost always upstream. That's where we start.

 

Can we trust our numbers enough to act on them?

GA4, the ad platforms and the back end report different figures, and teams use the same word for different things.

Is our media budget going where the evidence says it should?

Every platform claims the sale. Bidding algorithms optimise on whatever signal they receive.

Are we compliant, and can we prove it?

A cookie banner can work perfectly while a tag still fires before the visitor chooses.

Where should all our data come together?

GA4, the ad platforms and the back end report different figures, and teams use the same word for different things.

Which platform fits us best?

GA4, Google Analytics 360 or Piano Analytics. We advise independently and implement what fits.

What does AI mean for our data, and where do we start?

An AI application only works if what goes in is right, and AI agents now visit your site too.

We don't leave after go-live

A measurement setup starts breaking the day it launches. Platforms change, releases ship, consent rules move.

So we shape the strategy, design it, build it and keep managing it, with our own monitoring technology and a fixed monthly service instead of a bank of consultancy hours.

Strategy

Where does data make the difference?We start from your business goals and decide together what is worth measuring.

Design

A setup that fits your decisionsDefinitions, data layer and architecture, designed around the decisions your teams make, not the tools.

Build

Implemented and validatedTested against your own back end before anyone relies on it.

Management

Monitored every dayWe see what breaks before your dashboards do.

From 61% to 95% compliance at Sazas.

We checked every domain and app against 120 compliance points, fixed what failed, and now monitor it continuously, so the score doesn't slide back after the next release.

Consent research 2026

31%

Of 1,925 large Dutch commercial websites, nearly one in three starts tracking before the visitor has chosen.

On most of them, the cookie banner is still on screen while it happens. We measured 2,450 websites in total, including municipalities and public organisations.

 

Proud of our partnerships, in nobody's pocket

Partnerships give us specialist knowledge and direct lines to the vendors when you need them. They don't decide what we recommend. If another tool fits your problem better, we'll say so.
