Financial tracking built in a day.
10 years of spreadsheets, 28,719 transactions, 3 banks. In one day, full tracking: P&L, forecast, 60-day cash view. It found 368 duplicates and a VAT gap.
Hello, I am Thibault
An entrepreneur since 2016, founder of Oliverlist and VivaSync, with no outside funding. Several hundred million euros in sales opportunities generated for our clients. I made AI my right hand as a CEO, and I now help other CEOs do the same.
AI does not replace the CEO. It gives the CEO their time back, and leaves them the one thing that matters: deciding.

Positioning
Two ways of talking about AI to CEOs
On one side, advisers who explain AI without ever having put it into production. On the other, engineers who ship tools without knowing what running a company feels like. I run companies, and my agents work in them every day.
What I am
- A CEO who manages over 100 people day to day, in a company built with no outside funding.
- A builder who single-handedly built 84 agents and 13 applications in 4 months.
- A practitioner: every method I offer ran in my own companies first.
My path
Automate first, then AI, and always measure.
2016The start
Oliverlist, no outside funding
Prospecting for others
I founded Oliverlist: teams and tools that book qualified meetings for our clients’ salespeople. No funding round: our clients pay for the growth.
2020Automation
From contact import to invoice
3× revenue per person
I automated the whole chain: 225,000 emails per working day from nearly 7,800 mailboxes, 257 automated tasks, one invoice per meeting generated on its own. Between 2019 and 2023, revenue per person tripled, before generative AI.
2023AI in the product
The first agents
May 2023
First call to an AI model inside Oliverlist. Today, 24 agents tag replies, draft, spot meetings and coach the teams: about 648,000 decisions in 30 days, for about 1% of revenue.
2026The CEO job
AI, my right hand
84 agents in 4 months
From July 2026, I built on my own, with Claude Code, the agents that support my CEO work: finance, steering, sales, meetings, email. 13 applications, about 131,000 lines of code. The finance spreadsheet, Notion and n8n are gone.

Passing it on
What comes next
With VivaSync, I help other CEOs and leadership teams do the same, or explain how to. Every method ran in my own companies first.
Since 2016
Oliverlist has worked with these organisations
The stories I tell in meetings
Measured facts, including what did not work.
A booking agent built in a day.
Built in one day, live the next. It runs every 15 minutes and answers interested prospects. Its net effect is still being measured.
The $2.45 meeting.
Nora runs our meetings and publishes the minutes. A 21-minute meeting costs about $2.45. In a single pass, 31 meeting actions became tasks.
190 checks every night.
4 diagnostics run about 190 checks every night. Only the exceptions surface in the morning. 1,334 reports published, and Notion retired.
A recruitment firm in six days.
In September 2026, I built an automated recruitment firm in six days: finding companies and candidates, outreach, voice interviews, invoicing. It has been on hold since October.
What did not work.
The voice agent for client calls is on hold. And the big productivity jump, the 3×, came from automation, not generative AI. I say so in every meeting.
What I believe. What I prove
01
AI takes the repetitive work. The CEO keeps the decision.
Agents prepare, check and follow up. Anything that commits the company goes through human sign-off.
The proof
Overdue-invoice reminders are prepared from 7 days late, and approved by me.
02
Automate first, AI second.
A broken process stays broken with AI. We start by connecting the data and automating what is stable.
The proof
3× revenue per person between 2019 and 2023, before generative AI.
03
An agent without controls is a risk.
Every agent has its checks. An exception surfaces, a failed run is visible.
The proof
About 190 checks every night, 99.4% of runs successful.
04
A guaranteed return, because it is measured.
Every engagement has a quantified gain target, measured on your data. What is not measured is not announced.
The proof
I measure my own work too: an audit of 7,612 tagged replies found about 4 real errors per day.
05
Everything stays with the client.
AI accounts are in your name, access is under your control, and nothing is resold.
The proof
Reversibility: everything we build is documented and stays with you.
Guaranteed return
A guaranteed, measured return
Every engagement starts with a quantified gain target, agreed together and written into the proposal. It is measured on your own data, before and after.
A quantified target before we start
Hours given back, costs avoided or extra revenue: we agree on the gain we aim for, and it goes into the proposal.
Measured before and after
We measure on your own data, at the start and once in production. Tracking stays on a dashboard you keep.
Met, or I keep working at no charge
If the target is not met by the agreed date, I keep working at my own cost until it is.
If you have read this far, you already know what you want to hand over
In 30 minutes, you walk me through your day and your business. I tell you what AI can take over, and where to start.
30 minutes to see what can run without you
No commitment. You walk me through your week, I tell you what AI can take on, with a first estimate of the gain.
