Your interim growth person.
Validation, sales and marketing for startups and SMEs - one senior operator, paid for outcomes that matter.

Growth is stuck, and it all runs through you
You are the only one selling
Every deal needs you. Investors ask about your go-to-market and you change the subject. You built the product, but nobody built the revenue engine.
An agency already burned you
Months of retainers, nice reports, no pipeline. Agencies sell activity. You need someone who owns the outcome and does the work.
You cannot afford the senior hire
A full-time senior growth hire runs €60-100k+ a year, plus six months of ramp. Under 50 people, that math rarely works. There is a better way to get the same brain.
Tell. Sell. Excel.
Three stages, three ways to start. Every engagement is scoped to your problem, not to a retainer.

The 527% story
A 75-year-old manufacturer with €5M in revenue came to me with a strong product and an invisible brand. We repositioned the company, rebuilt the story, and took the new offer to market. One product's yearly profit grew 527%. No new machines, no new staff - the same product, finally told and sold right.
single-product yearly profit, €5M manufacturing client
funding secured for a client, plus a full production plant build
total yearly costs after supplier renegotiation for an SME
qualified pipeline built, 14 straight quarters over quota
countries opened across 6 continents as a co-founder
team scaled, new-hire turnover cut from 54% to 6%
