Growth,
engineered.
For the operators who refuse to outsource judgement.
A craft discipline, applied to growth.
Marketing, at its highest level, is an engineering discipline — one that rewards rigour over noise, systems over heroics, and patience over urgency.
We work where strategy meets execution. Marketing is no longer a creative function bolted onto a business — it is the operating system of growth itself. Every channel, every campaign, every funnel is a system that can be designed, measured, and improved upon.
We build durable acquisition systems that compound over months and years — systems our clients can defend, scale, and reason about with confidence, long after the engagement ends.
Systems, not tactics
Every recommendation is a system we can operate, document, and hand off. No black boxes, no proprietary opacity, no dependency on personality.
Capital efficiency first
We optimise for sustainable unit economics before scale. Profitable growth compounds. Unprofitable growth dilutes — every time, without exception.
Senior attention, always
Engagements are led by principal-level operators throughout. No junior delegation, no account-management theatre, no diluted attention.
We do not chase trends. We engineer the infrastructure that makes growth inevitable.
A complete growth operations capability set.
Eleven disciplines, deeply integrated. Each offered as part of a coherent engagement, never as a standalone deliverable. The whole is engineered to compound.
How we work together.
Every engagement follows a deliberate sequence — from diagnosis to design to disciplined operation. The framework adapts. The rigour does not.
Diagnose
A structured audit of channels, funnels, infrastructure, and the underlying growth model. We surface what is working, what is broken, and — most importantly — what is missing.
Design
A blueprint for the next phase: channel priorities, measurement architecture, creative direction, and the operational rhythm required to execute it without drift.
Operate
Disciplined day-to-day execution. Weekly optimisation, monthly performance reviews, and the operational consistency that compounds quietly over time.
Scale
Once unit economics are proven, we expand deliberately — new channels, new geographies, new customer segments — without compromising what already works.
Built by operators,
for operators.
FZ Group was founded on a simple conviction: that marketing — at its best — is an engineering discipline. It rewards rigour over noise, systems over heroics, and patience over urgency.
We work with a small number of operators who share that conviction. Founders building serious companies. Operators scaling beyond the first growth curve. Teams that have outgrown their first marketing solution and are ready for the second.
The work is meaningful. The engagements are long-term. The standard is uncompromising.
Managed by its members Marco Pascal Ziegler and Marc Fischer.
Considered notes from the studio.
Working notes on growth operations, attribution, capital efficiency, and the craft of marketing as engineering discipline. Published when there is something worth saying.

The most expensive line item on a CFO's marketing P&L is the channel you only think is working.
Why last-touch attribution flatters the wrong channels — and what to do instead, without becoming the kind of marketer who talks about incrementality at dinner parties.

Why we shrunk the budget by 38% in quarter one — and what happened next.
A counter-intuitive engagement note: the most efficient way to lower CAC isn't to optimise bids. It is to give the brand creatives worth pausing for.
Read note
Compounded cohort value is the only growth metric a board should care about.
Why we model 24-month cohort economics before we choose a channel — and why most performance dashboards quietly punish patience.
