About MetricMavens
The strategic data partner you’ve been looking for.
Lean enough to move fast. Senior enough to handle complexity. Strategic enough to connect your full journey.
Most agencies can implement. Very few can activate for value. We fill the gap between consultancies who strategize but don't execute and technical teams who execute but don't but don't question if it's right.

Industries we serve
We've solved complex data challenges across retail, ecommerce, B2B, automotive, hospitality, FMCG and more. But our approach isn't industry-specific—it's challenge-specific. If you're dealing with fragmented customer data, attribution problems, or insights that don't drive action, we can help.
RETAIL
Connect online research to in-store purchases across the ROPO journey.
B2B
Multi-touch attribution across long sales cycles and complex buying committees.
HOSPITALITY
Unified guest data from research through booking, stay, and loyalty programs.
ECOMMERCE
Multi-channel attribution, CLV prediction, and subscription retention optimization.
AUTOMOTIVE
Connect digital research, dealer visits, and test drives across 18-month journeys.
FMCG
DTC and retail data unified: track consumers across online and in-store channels.
Our Values
Our values aren't marketing. They're commitments we make to every client, every project, every conversation.
Direct
No spin. No corporate-speak. No hiding behind jargon when we don't know something.
If your strategy is flawed, we'll tell you and show you why. If a project is running behind, you'll hear it from us first. Straight talk over smooth talk, always.
Growth-Minded
We stay ahead of the curve so you can too. Relentless about learning and evolving.
We're testing new AI models before they're hyped. We're exploring emerging platforms before they're mainstream. We bring fresh thinking, not recycled playbooks.
Always Curious
We see connections others miss. We don't stop at the brief but we explore what's possible beyond it.
You ask us to "fix attribution" and we discover the real problem is fragmented customer data. You ask for "better dashboards" and we uncover that insights aren't the issue, action is.
Collaborative
We solve for your whole business, not just one department. Marketing wins that hurt Sales aren't wins.
We bring Marketing, Sales, Product, and Success into the same room. We design solutions that benefit everyone. Dependency isn't partnership.
Pragmatic
We optimize for results, not complexity. What works beats what's trendy.
If a €5K solution solves the problem, we don't recommend the €50K one. If your current tools can do the job, we don't sell you new ones. Simple beats clever.
