Loïc Boutet

Founder of 5000.dev

I'm a developer, but I've always been an entrepreneur first. I've launched 3 products and created 3 agencies, the largest with 50 people, including 35 developers.

I've managed €15 million in projects, the largest being €2 million over 4 years. I know how to build software.

I know the struggles of IT projects. I know the challenges of launching projects too. I understand that you spend your time managing a thousand things, and not enough time building your vision.

I want to be your solution.

17 years of development experience

  • I started with Ruby in 2006, when Rails was just emerging.
  • I founded and led an agency with 50 people.
  • I've delivered +80 projects for startups and major clients (Doctolib, SNCF, Thales, Accor...).
  • I've managed €400K+ projects in healthcare, retail, and industry.

I've seen all the pitfalls of tech projects

  • I've seen 100-page specs transform into 200 pages.
  • I've experienced all the traps of large tech projects.

💡 Do you recognize these problems?

Most tech projects fail because of these classic traps. That's exactly why I created a different approach.

Acceleration through AI

In the past two years, I've revolutionized my coding approach. I specialized in generative AI applied to development.

  • I've developed acceleration tools that cut development time by 75%.
  • I've created systems that generate testable and maintainable code.
  • I've guided startups and companies in their transition to AI.
  • I've coded applications that generate €80K in annual savings.

That's why I created 5000.dev

A simple promise: applications in 2 weeks for €5,000.

Slow to 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.

A solution tailored for entrepreneurs and creators

Custom applications without the usual complications of IT projects. Built step by step.

Few meetings 30+60 min

Only two meetings: 30 minutes to see if we're a good fit, then 1 hour for specifications. That's all the time we need from you.

Frequently Asked Questions

Everything you need to know about our process and how we work

How does the step-by-step method work?

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

Is the design/UI of my application included?

Absolutely! The €5,000 includes everything—UX/UI design and mockups are a crucial part of our process. We create professional, intuitive interfaces tailored for your users. No need to hire a separate designer.

What happens if you don't deliver in 2 weeks?

If we don't deliver your application within the agreed 2 weeks, you can cancel the contract and be fully refunded. That's our guarantee: delivered in 2 weeks, or refunded. We take this commitment very seriously.

My needs are complex, is it possible?

Yes! We break down your project into multiple €5,000 modules, each delivering usable features in 2 weeks. You control your budget and can adjust priorities between each module based on real user feedback.

What's included in a module's price?

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