Growth marketer · SEO, GEO and paid · 8+ years

I build growth engines, and fix the ones that broke.

Eight years across B2B AI, consumer apps, marketplaces and high-scale B2C, usually where the system had to be built from nothing or recovered under pressure. I have led teams of 20, managed €500K a month in ad spend, and run a whole growth function alone with AI.

Expertise

Seven things I am actually good at.

01

Paid acquisition

Google, Meta, LinkedIn, ChatGPT, TikTok, Reddit and X. From €500K-a-month B2C scale to B2B pipelines and ABM built from zero.

  • Cost per signup $1,000 → under $4
  • ROAS 2.0 → 3.5
  • Three-layer ABM warm-up
02

SEO at scale

Topical authority rebuilds, recovery after Google updates, and technical SEO on sites with hundreds of thousands of pages.

  • 22M → 50M+ monthly users
  • 400K → 700K post-HCU
  • 4K → 28K+ in two years
03

SEO and GEO with AI agents

Search and generative engine optimisation run through Claude agents, with in-depth MCP and API integrations into the tools I use.

  • 0 → ~15K AI citations a month
  • ~40% generative share of voice
  • +211% AI Overview appearances
04

Partnerships and links

Widget and API programmes, data campaigns and outreach engines, built from nothing more than once.

  • 2M+ links, 200+ partners
  • ~3% outreach conversion
  • Link teams built from scratch
05

Leadership

Years of leading SEO, content and outreach teams. Strategy set centrally, support given person by person.

  • Teams of up to 20
  • 7 senior SEOs, 6 juniors, writers
  • Hiring and mentoring
06

Building things

An e-commerce store, a content site, an SEO course, YouTube channels and now a live mental-health app.

  • VentSpace, live on Google Play
  • Sites built and migrated solo
  • SEO writing course sold
07

Marketing automation and a swarm of agents

I run a team of Claude agents, each built for one job and wired into the marketing stack through MCP and APIs. They do the repeatable work, watch the numbers and flag what needs a human, so one operator can run GTM at scale.

  • Content writing
  • Content updates on decaying pages
  • Internal linking
  • Technical SEO audits and fixes
  • Backlink campaign management

Ads agents

  • Negative keyword monitoring over MCP
  • Alerts when numbers or engagement drop

  • Account scoring by touch count
  • Mass outreach to warmed accounts

Demand creation, intent capture, conversion, revenue. One system, not four channels.

Downstream signals

I optimise for qualified leads and pipeline, not clicks and impressions.

AI-first operator

AI tools and agents run through research, content, creative testing and reporting.

Test velocity

Small bets, fast reads, then scale what wins. A habit from years of always-on ads.

Mar 2026 to presentRemoteB2B · Web data for AI

Running SEO, GEO, paid and account-based marketing for a B2B web data company that sells to AI labs, healthcare data resellers and enterprise data teams. Search demand in this niche is small, so I built the pipeline around accounts, not just keywords.

  • Scored accounts by touch count (3+ touches = priority one), with 1,052 companies de-anonymised through RB2B as one signal.
  • Healthcare: 250 reseller accounts at $150K+ deal sizes, CTR up to 10% from the largest US health-supply buyers, turned into a 390-person decision-maker list.
