IAI consulting & automation

Your data and your know-how, in one place, for a smarter, faster business.

  1. An AI is only as good as what it knows about your business. Your customer data, your sales and your know-how are scattered across people's heads, files and software. I bring them together into one knowledge base, the shared source for all your AI agents: their memory, and what they learn from every time your team settles a new question.
  2. I advise before I build. Together we find the tasks with the most impact, in time saved and in money, we pick the tools that suit you, and you know what each project should return before you commit to it.
  3. On that foundation, uses vary from one business to the next. For one, it's an advisor that answers customers on the platform where they write, and hands over to the team at the right moment. For another, agents and automations between its tools, on Make, n8n or in custom code. Everything I deliver stays yours, and I train your teams to use it.

Knowledge base

Your data and your know-how in one place, the shared memory all your AI agents draw on and learn from.

IIServer-side tracking

Measurement that sees every sale, so your ad platforms bet on what sells.

  1. 99% of the tracking setups in place could be improved. Between ad blockers and duplicate tags, sales get lost or counted twice. And a sale Google Ads or Meta can't see is a sale they can't learn to repeat.
  2. The right measurement depends on your budget and your sales cycle. On a small budget, well-built browser tracking is enough. As spend grows, collection moves server-side, with server-side GTM and the conversion APIs. When the sale closes later, at a meeting or on the phone, your CRM or your backend sends the conversion back to the ad platforms. And if your customers go through an iOS or Android app, it is measured with Firebase and talks to the ad platforms just like your website.
  3. Wherever you start, consent holds from end to end. I work with the CMP you already have or one that suits you, and your visitors' choice is respected all the way into the server.

GTM & server-side

Collection routed through your server, so your ad platforms see the sales the browser loses.

E-commerce (furniture and lighting)

+45% sales seen

Over the same six months, Google Ads sees 45% more sales through the back office than through the browser, and the client saves about €800 a month on a third-party tool.

One sale, sent twice with the same ID, is counted only once.
  • Loungitude

    The paid order goes from the shop to GA4, Google Ads, Meta and TikTok, without relying on the visitor's browser.

  • Closer Deck

    The shop's carts and purchases sent to LinkedIn, each counted only once.

Le CabPrivate-hire rides

Website and apps together

The website, online booking and the iOS and Android apps in one measurement setup, so the marketing team could see in Google Ads which bookings its campaigns brought in.

  • Petit Marché

    iOS installs weren't showing up in Google Ads: the missing setting found in Firebase, and the conversion imported.

IIIGoogle Ads & Meta

Campaigns that learn from your real sales, and a budget that goes where it pays.

  1. I've been running Google Ads and Meta campaigns since 2017, with budgets of up to €150,000 a month. From local businesses to big-spending e-commerce, I shape the account structure around your market and your margins.
  2. Every account starts from a different place. An account taken over often needs to be put back on its feet before it gets more budget. A healthy account gains most from bidding on what earns you money, the confirmed sale or the lead that became a customer, sent back from your website or your CRM.
  3. My monthly management follows the rhythm of your business. I optimise from periodic and seasonal analysis, and your peak periods are prepared ahead of time. Every change is dated and logged: we can always trace how the account evolved and explain it. Reporting takes the form you want to read, from a dashboard to a monthly review, and it talks revenue and cost per sale.

Google Ads & Meta

Accounts structured by purchase intent, tested and cleaned up continuously.

IVData & Analytics

Your numbers, from the first click to the sale. Dashboards people actually want to open.

  1. When your tools don't give the same number, no decision holds. I put measurement back on its feet in the tool that suits you, GA4, Matomo or an in-house solution, so a sale carries the same name and the same value on the website, in the CRM and in every ad platform.
  2. How deep we go depends on your questions. A Looker Studio dashboard plugged into your sources is often enough. To follow a customer from the first click to the repeat purchase, I bring your data together in BigQuery and model it.
  3. I also get involved in reading the numbers. I analyse them with you and teach you to make them talk. And if the question goes beyond analytics, behavioural data or another attribution model, we look at it together.

Analytics & BigQuery

GA4, Matomo or your in-house solution, consistent with your ad platforms, with your history kept in BigQuery.

Software publisher (marketing automation and CRM)

4 business sources and GA4

Let's scope your data needs

VDevelopment & products

Websites that convert, custom software, all wired into everything that runs your business.

  1. A landing page is judged by what it converts. I start from your numbers and from what your visitors really do, click maps and session recordings, to fix what holds them back: an unclear message, a form that's too long, a page that's too slow. Every change gets tested, and we keep what lifts the conversion rate.
  2. I choose the technology with you, based on who will run the tool afterwards. Sometimes it's the tool your team already knows, sometimes custom development, on the web or as a mobile app, designed as a product we improve as feedback comes in. The code and the data stay in your name, and your team publishes its content without going through me.
  3. After launch, I stay on for maintenance and support. I build the alerting and monitoring tools that track the health of your services: a form that no longer sends anything to the CRM, a sync that breaks, a page that slows down. You're warned before it costs you sales, and I fix it.

Landing pages & CRO

Fast pages, measured from launch, then tested and reworked to convert more.

Yoann Regis, the person behind the stats.

Picture Sheldon Cooper, Indiana Jones and Mr Miyagi having a child. I'm an odd hybrid of incurable geek, travel lover and seeker of inner truth. I practise tai chi and yoga, and I love connecting with the world's spiritual cultures as much as with a games console. That mix is how I work: empathy, listening, and a real human connection behind every line of data. A happy dad since 2025, I'm always looking to give my beloved daughter the chance to grow up close to the soil and the trees.

Freelance since 2018, I want to understand and master the web for my clients' sake: agencies, advertisers, e-commerce, public institutions. Based between Haute-Savoie and Eindhoven, I work remotely, in France and internationally (FR, EN, NL).
