What we do

Three things, done brilliantly.

Most agencies sell motion. We sell direction. Pick one — or wire all three together for compounding growth.

Our philosophy

Not more marketing.
Marketing that compounds.

We work slowly, with very few clients, and only on things we believe will compound. No retainers without a plan. No plans without a thesis.

From €2.2M to €4.4M ARR in 12 months.

A B2B fintech scaling Series A to Series B came to us with paid acquisition that worked, but inconsistently. We rebuilt their LinkedIn, Google, and Meta programs from the channel mix down to the creative system — testing 500+ ad variations to find what actually compounded.

How we work

No retainers without a plan.

Three steps, repeated quarterly. We diagnose, build, then compound — measuring everything against the original growth thesis.

01
— Two weeks

Diagnose

We audit your funnel, site, brand and channels. You walk away with a written growth thesis — yours to keep, regardless.

02
— Six weeks

Build

We ship the highest-leverage 1–3 things first. Infrastructure, content, landing pages, sequences — whatever moves the number.

03
— Quarterly

Compound

Monthly review against the thesis. We double down on what works, kill what doesn't. Growth becomes a system, not a sprint.

★★★★★
“Most agencies sell you motion. OnlyGrow sells you direction. Six months in, they're the only outside team I'd hand my brand to without watching over their shoulder.”
