I build the lead lists other teams give up on.
Targeting, enrichment and AI-native workflows for B2B outbound. I turned years of hands-on list building into an engine that ships a complex, verified prospect database in 10 minutes instead of 2–3 days.
From a brief to a CRM-ready list.
The best outbound copy can't save a bad list. Every file goes through the same waterfall, with every source checked and every contact verified before anyone pays for it.
Brief & ICP
Turn “who do we sell to” into criteria a machine can apply: unit, size, signals, roles.
Market map
Company registries, open data and scraped directories for an exhaustive account universe.
People data
Waterfall enrichment across several providers to find the right decision-makers.
Live check
Is this person still in the role today? Verified before paying for a phone number.
Ready to send
Emails, mobiles, context: a clean file for your CRM or sequencer.
What I do.
Lead-list engineering
Hard-to-target markets mapped end to end: the most precise targeting and the most complete coverage you can get.
Enrichment & verification
Waterfall enrichment with spend caps and live checks: no budget wasted on people who already left.
AI-native GTM workflows
Python and LLM agents that run list building on their own, with tests and guardrails, not a fragile pile of zaps.
Numbers, not adjectives.
leads contacted every month through the list-building system and Clay templates I designed, used by ~10 CSMs across ~20 recurring clients.
meetings booked in a single week from ~2K contacts, on a 70 meetings/week goal, with ~6K new targeted leads sourced every month.
ongoing prospect data program for one of Europe's largest telecom operators.
pipeline in year one, starting with no CRM, no data and only referrals: ICP, database, CRM and multichannel campaigns built from scratch.
The stack behind the lists.

Opened the Moroccan market for a healthcare software company.
A seller who learned to build.
I started on the phone: 150 cold calls a day, then opening a new market in Morocco for a healthcare software company, from mapping the ecosystem to building the first distributor network.
Every time, the same thing made or broke the quarter: the list. So I went deep on it. Scraping, enrichment, Clay, then Python and AI agents, until the know-how fitted in a system that runs on its own.
Today I'm the person sales teams call when the market is too niche, too fragmented or too messy for off-the-shelf databases. MSc in International Sales & Negotiation, IÉSEG (AACSB, EQUIS, AMBA). French native, fluent in English.
