Build with AI agents.Without breaking things.

AI agents write the code. Guardrails check every change before it ships. Your team takes it over. And when something breaks that they can't fix, I fix it.

No dev team? I build it for you. Want AI on your customer messages? I set that up too.

Who it's for

Which one sounds like you?

Three different starting points. The same way of working.

A

You have developers

CTO · head of engineering

"Our developers use AI tools, but we don't trust what comes out. Bugs slip through and nobody checks."

What I do

I put guardrails, CI/CD checks and AI review on your code, and train your team to work this way.

B

You have no dev team

Founder · owner

"We want to build a product but can't afford a full dev team."No technical co-founder? Outgrown your no-code tool?

What I do

I build it with AI agents, then hand it over with the guardrails already in place.

C

You want AI on your data

COO · ops lead

"We want to use AI on our customer messages and documents, but we don't know if it works or which model to use."

What I do

I test AI on a sample of your own data, then build the flow and hand it over.

How it works

Start small. Build. Hand over. Stay on call.

Three steps. You decide after each one.

The guardrails

AI writes the code. Nothing ships unchecked.

This is the pipeline I run on my own product every day. You get the same one.

AI on your own data

AI that reads, drafts, and waits for a person.

How the AI handles every customer message in my own business. The same shape works on your messages, emails or documents.

Proof

I did it on my own business first.

Your Bike in Bali is a scooter rental business that sells and runs over WhatsApp. I built all of its software as the only developer, working with AI agents, in 20 weeks. It runs the business every day.

Before that I led teams of 5 engineers: Danske Bank's 16,000-server move to AWS, AT&T's migration framework.

Before AI agents

10 years of data and cloud, at scale.

Danske Bank

Framework to move 16,000 servers to AWS in 2 years. 90% of migration tasks automated.

AT&T

Used Amazon Bedrock (Claude) to generate the infrastructure code for target servers.

Enovos

Data warehouse moved to AWS: 5 sources, about 200 tables.

Carrefour

Pipelines moved to Google Cloud: 300 to 400 tables, every customer ticket.

Axa

Central data lake and real-time ingestion. CI/CD for a team of 20 developers.

Air France

Real-time ingestion of millions of booking events a day.

Price

First-client price. For the first 5 clients only.

After the first 5, the price goes up. With your OK, your project becomes one of the case studies. Prices excl. VAT.

About

Brian Blessou, founder.

I spent 10 years building data platforms and cloud migrations for banks, telecoms, retailers and energy companies, leading teams of 5 engineers.

In 2026 I built my own business's software alone, with AI coding agents. What made it work was not the AI. It was the guardrails around it: written rules, automatic checks, a second AI reviewing the first, and a person approving every release.

Now I set up the same thing for you, and stay on call after.

Questions

Before you book.

Who owns the code?

You do: the code and the guardrails. You pay your own AI and hosting bills, so nothing depends on me.

What happens to our data?

Your data stays in your accounts. The AI providers are used with no training on your data. NDA on request.

How much will the build cost?

Start ends with a fixed quote. No surprise.

What if we stop after step 1?

You keep the written findings and the fixed quote. Each step is a separate decision.

Which AI do you use?

The one that wins on your case. I test the main providers on your own data before choosing, the way I tested three on my own business.

Does AI replace my developers?

No. Your developers decide and approve. The AI writes, the guardrails check, a person says yes.

Where are you, and in which language?

I work remotely in English and French, in European and Asia-Pacific working hours.
