Fractional Head of Growth + AI Architect · Hamburg

Most fractional CMOs don't build. Most AI consultants don't run growth. I do both.

For €5–50M ARR e-commerce and apps. I audit the stack, kill three vendors, build the replacement in-house, and operate growth for 90 days. Then I leave it running.

The rare combination: build and run.

I'm Alejandro. Ten years inside paid acquisition, attribution, and the unsexy plumbing that makes a growth team actually compound. The fractional CMO market is full of strategists who hand you a deck and a retainer. The AI-consultant market is full of builders who've never run a CAC payback model. I sit between the two: I audit your stack, replace three vendors with a system I build in-house, then operate growth myself for 90 days before handing it back to your team.

The 7-vendor cull I run on every new engagement.

  • How I identify the 3 vendors costing more than they earn
  • The in-house replacements I install (and what they cost to maintain)
  • Why €5–50M ARR is the sweet spot — and the trap below €5M

Audit Sprint

Stack audit + kill list. €40–80k, four weeks.

I audit acquisition, retention and attribution. You leave with a written kill list, replacement architecture and implementation plan. If we don't find at least €100k/year in saveable spend, you don't pay the second invoice.

Operator Retainer

I run growth for 90 days. €20–30k/month.

Audit included. I rip out vendors, install the system, hire and train one in-house owner, and run paid acquisition + automation myself until it's compounding. Then I leave.

Why €5–50M ARR is the only window where 'Fractional Head of Growth + AI Architect' makes sense

Below €5M too early, above €50M you need an internal team. Here's the math.
