You spend €2M on marketing. How much of that goes to customers who'd have bought anyway?

Magpie shows the true effect of your marketing.

Talk to Founders

When targets go up, the questions get harder

“What happens to revenue if we cut paid social by 30%?”

“Which channels are actually driving the first purchase??”

“Are we just buying our own organic traffic?!?”

Magpie: the Models & the Minds

We don't just hand you a login to a tool. We combine three proven data models with a human (yes!) data scientist to help you challenge assumptions and simulate budget shifts.

Custom made models.

We measure what happens to customers and revenue when marketing changes

Customer journey data

We look at the micro-level touchpoints to see what actually nudges a user toward a purchase.

Historical Data (MMM)

We analyze how your revenue fluctuates over time as spend moves across different channels.

Experiments

The gold standard. We measure what happens to your bottom line when spend actually increases or stops in a specific region or channel.

The minds. Data science
as a service.

You work directly with marketing data scientists who act as an extension of your growth team. We:

Challenge assumptions (even the ones you like).

Interpret the results so you aren't just looking at charts.

Calculate budget scenarios to simulate "what-if" changes before you commit.

Identify growth opportunities that your standard dashboard is currently missing.

Knowledge sessions, presentations and proactive advice.

Why both matter:

tools alone don’t change marketing, and advice without data is guesswork. We combine both, so you see what drives customers and act on it.

FOUNDERS

Why we built Magpie

After years at two of the most data-driven companies in the Netherlands - where we could measure marketing down to the last cent - we came to one conclusion: this needs to be more accessible...

Magpie is for your organisation if

You’re growing fast and want to accelerate that growth in smarter, more effective ways.

You look beyond dashboards.

You ask yourselves: “Would we have acquired this customer anyway?”

You’re okay with the possibility that your favorite 'high-ROAS' channel might actually be doing nothing

You don’t settle for “last-click says it works.”

You’re after the truth, not confirmation.

You want to rigorously test your assumptions.
