About

A boutique consultancy for pivotal moments

Zero Limit was founded on a simple conviction: the most valuable consultants are the ones who've built businesses themselves — not just advised on them.

We bring direct operational experience to every engagement. We've incorporated companies, hired teams, closed enterprise deals, managed P&Ls, navigated regulators, and grown revenue from zero to seven figures. When we advise, it's from experience — not theory.

Our network of associates spans AI engineering, data privacy law, blockchain architecture, and financial services compliance across Europe, the UK, and the Americas. We assemble the right team for each engagement.

Based in Paris, operating globally. We work in English, French, and Spanish — navigating cultural complexity both internally and client-facing.

Damien Ducourty

Founding Partner

25+ years building businesses from zero across financial services, telecoms, Web3, AI, and data privacy. Dual French-British national. Previously Founder & CEO of B9lab (€7M revenue), Partner & COO at Vishon (X8 AUA, FCA-regulated), and Head of BD at Digiterre (700% YOY growth).
