Loïc Boutet

Founder of 5000.dev

In 17 years, I've explored every aspect of web development.

I started with Ruby in 2006, when Rails was emerging.

I founded and led an agency of 50 people.

I delivered +80 projects for major accounts (Doctolib, SNCF, Thales, Accor...).

I managed projects of 400K€+ in healthcare, retail, and industry.

I've seen 100-page specs turn into 200 pages.

I've experienced all the pitfalls of large tech projects.

In the last two years, I've revolutionized my way of coding.

I specialized in generative AI applied to development.

I developed acceleration tools that divide development time by 4.

I created systems that generate testable and maintainable code.

I helped companies transition to AI.

I coded applications that generate 80K€ in annual savings.

That's why I created 5000.dev

A simple promise: web applications in 2 weeks for 5000€.

No endless meetings. No spec drift.

Just working code, delivered quickly.

This offer is for you if...

  • You're a non-tech entrepreneur wanting to quickly validate an idea
  • You run a design agency looking for a reliable tech partner
  • You're an SME wanting to digitize a simple process
  • You're a startup needing to test a concept
  • You want professional development without the usual complications
  • You want to build a Gen AI application

This offer is not for you if...

  • You want to create an e-commerce site (→ Use Shopify instead)
  • You want to create a CRM (→ Use HubSpot or Monday instead)
  • You need a native mobile application
  • You want to modify existing code
  • You want a fixed quote on a long list of specifications (→ We work iteratively on complex projects)

Traditional tech projects are...

Slow to start

3-4 weeks of meetings before the first line of code. At this pace, your competitor will have validated their market before you even start.

Budget overruns

Complex quotes, hidden costs, and that famous phrase "it depends". Impossible to plan with confidence.

Risky investment

Building for 6 months only to discover it's not what your users wanted. Every entrepreneur's nightmare.

Too many contacts

Sales rep, project manager, junior dev... Nobody really understands your business needs.

What my clients say

"I had this vision for Octogo.ai that I'd been carrying for over a year - creating THE reference platform for AI tool selection.

The most impressive part? Not only does the result exactly match my vision, but the first users adopted it immediately."

Frequently Asked Questions

How does the brick method work?

It's simple: we break down your project into two-week bricks. Each brick costs €5,000 and delivers 2 to 4 concrete features. We develop one brick at a time, allowing us to learn and adjust continuously.

My project is bigger, is it possible?

Absolutely! That's the whole point of the brick method. We break down your project into multiple €5,000 bricks, each delivering usable features in 2 weeks. You control your budget and can pivot between each brick if necessary.

How does a brick work in practice?

Simple and efficient:
  1. We define 2-4 features for your brick together
  2. We formalize the contract and you pay for the brick
  3. We create mockups for validation
  4. We develop and deliver in 2 weeks

How do you guarantee the timeline?

After +80 projects, I know exactly what's achievable in a two-week brick. I only accept projects that fit this format. If I don't deliver on time, you get a full refund.

What's included in a brick's price?

The €5,000 includes everything: needs analysis, mockups, development, documentation, and production deployment. Only hosting is extra if you choose the managed option (€50/month).

How do I start my project?

Start by taking the eligibility test. If your project fits our format, we'll schedule a 30-minute call to define your first brick.
