About Marta Berggren
A marketing practice built to be accountable.
Marta Berggren was founded on a simple premise: marketing spend without measurement is a guess wearing a suit. We build the tracking first, then the campaigns — so every decision has a number behind it.
Founder-led, by design
No hand-off, no diluted brief
Marta Berggren leads every engagement personally. That means no hand-off to a junior account team and no diluted brief — the person who scopes the strategy is the same person who reviews the numbers with you each month.
The practice was registered in 2026 in Sceaux, France, and works with clients across English- and French-speaking markets, combining hands-on campaign management with the kind of call-tracking and reporting infrastructure normally reserved for larger in-house teams.
How we work

A written plan covering promotion, advertising and reputation priorities, ranked by expected impact.
Execution & tracking
Campaigns go live with call tracking and analytics wired in from day one — not bolted on afterwards.

Monthly reporting in plain language, followed by the changes the data actually supports.
What guides the work
Three commitments, kept on every engagement
Measured, not guessed
Every recommendation is tied to a metric agreed on in advance.
