About

I build AI-native marketing engines — agents, workflows, RevOps — that produce pipeline before headcount. How: I don't just set strategy, I build the system that executes it. Classic growth and RevOps discipline, orchestrated through Claude — agents, skills and automations at the core — with Clay, n8n and HubSpot interconnected around it. Acquisition engines that compound instead of relying on an ever-bigger team. Proof of range: Ex-CMO at Divante (→ Cloudflight Digital Commerce, PE-backed). Scaled marketing 3 → 26+ across Poland, EU, US and MENA, carried GTM through three M&A processes and an international rebrand — ~30M PLN/year in new business on a €1M+ budget, reporting to PE stakeholders. 45–58% YoY growth sustained. What I bring to a founder-led team: • Lean structures where everyone contributes to revenue — no passengers • Human judgment paired with an AI workforce doing the heavy lifting • Fast time to market — ship, validate, iterate • Operator first, not an infinite strategist • Business sense — metrics, unit economics, profitability, not marketing vanity • Ruthless prioritization (committed Pareto fan) I'm looking for one senior seat — CMO / VP Marketing / Head of Marketing / Head of Growth — at a B2B software company that wants to scale smarter. Strongest in complex, long-cycle categories: SaaS, cybersecurity, defence-adjacent. One seat, full commitment — portfolio engagements wind down on signing. If that's you — let's talk.
