Who does the work?
Leo Loison. B2B growth marketing consultant and paid acquisition specialist, ten years.
I work from Sofia with companies across Western Europe, in English or French.
At simpleclub I launched the B2B unit from zero inside a company that had only ever sold to consumers: HubSpot, attribution, lead routing, Google Ads and LinkedIn Ads, built from nothing. Then I ran it for four years.
A year inside a 210-person performance marketing agency. I know how that model works from the inside: who is on the kickoff call, who does the work afterwards, and why the two are rarely the same person.
No account managers. No junior consultant doing the work while I'm on the kickoff call.
I've been training junior marketers for a decade: three interns at expondo, PPC trainees at Peak Ace, a team of four at simpleclub.
AI is why one person delivers what an agency staffs with four.
Has this worked before?
Ten years of B2B paid acquisition, and the same result in three different companies:
| Company | Result |
|---|---|
| Jeff.com | 2x MQLs across 15+ markets, conversion quality held |
| EMnify | 3x MQLs, from 100 to 300 a month, at a stable MQL-to-SQL ratio |
| simpleclub | 4x MQLs over twelve months, conversion quality held |
MQL: marketing-qualified lead. SQL: sales-qualified lead.
Three companies, three product categories, three team structures, spanning seven years. One result is luck. Three is a method.
Any agency can show you a volume chart. Far fewer will show you what happened to lead quality.
At expondo, an equipment retailer, I took a Google Ads account from €25,000 to €100,000 a month over two years without letting cost of acquisition drift, and quadrupled revenue on that market. I repeated the pattern on a second market.
Seven markets at EMnify: UK, US, France, DACH, Italy, Spain, LATAM. 15+ markets at Jeff.com.

What I do not have yet is a published case study under my own name. I started this practice in May 2026. That is precisely why the first step costs €950 and not €6,600, and why payments are monthly and follow delivery. If you choose handover, it is also why I do not send the final invoice until your marketer has run the engine without me.
