What we deliver

One studio for every type of project.

Whatever the platform, the method stays the same: pin down the essentials, build cleanly, deliver. Whatever your starting point — a new idea, a product to extend, an existing one to rebuild — we support you through to deployment.

Already started?

A project to take over or rebuild? We start from where it is.

Not every project starts from a blank page. Whether it is stuck midway, ageing, needs to be made reliable or expanded, your project fits the same package of €4,000 in 30 days. Reviewing what already exists is part of the first week’s scoping.

Who’s behind it

Anyone can run an AI. Knowing what to ask it, and taking that to maintainable code in production, is a different job.

The model that writes our code writes everyone else’s too. What changes is everything around it: deciding what to build, then taking what it produces — reviewing, testing, hardening — until it holds up in front of real users.

You can’t ask a model for that: it comes from shipping products that people use. Our team has done it since 2013 — more than eighty projects taken to production, long before AI wrote a single line.

Why us

The same product, without the six months.

Here is an honest comparison. Each option has its merits. For us, what matters is moving fast, at a fixed price, with no compromise on quality.

The method

Four weeks, a steady pace.

No six-month black box. A clear framework, weekly milestones, and visibility from the first day to the last.

01
Week 1

Scoping & Documentation

Scoping workshops, mock-ups and user journeys, functional specifications and requirements document. You approve the Documentation: it sets what the package includes.

Mock-ups & user journeys·Functional specifications·Approved requirements document

02
Week 2

Foundations

Development starts: architecture, data model, authentication and shared services. The first user journey comes to life, deployed on an online environment.

Week 3

Full functional scope

The entire scope of the Documentation is developed, with screens and features integrated. On Friday, we give you a demo of your product.

Acceptance testing & delivery

On Tuesday at 9:00, after the final instalment, you receive the pre-production link and your test access. Your feedback is due on Thursday at 13:00. Your product is production ready by the following Tuesday at 17:00 at the latest. All that remains is the switch-over, and the code is yours.

What’s included
  • Scoping workshop and project scope
  • Interface design & mock-ups
  • Complete full-stack development
  • Deployment to an online environment, ready for production
  • Supervision by a senior developer
  • Weekly progress check-ins
  • Source code & 100% ownership
  • 2 weeks of support after delivery
After the 30 days

Your product is ready and online in pre-production. The switchover puts it into production, for the general public.

You’re already using it for real and having people around you test it. The switchover is what remains: your domain, the certificate, the store accounts, monitoring and backups.

We offer a fast switchover to an environment we run. Fast, because pre-production and production are the same infrastructure: your application is already on our servers. Nothing to migrate, no configuration surprises. We connect your domain, and it’s live.

The switchover costs you nothing. What is billed is production hosting: a monthly service, separate from the package. Optional — the code belongs to you, nothing obliges you to stay with us.

Four plans
EssentialStatic site, managed database and authentication
Standard1 vCPU · 512 MB · dedicated database
IsolatedVirtual machine reserved for your project · independent system · allocated resources
DedicatedDedicated physical machine · hardware isolation · unshared resources

The price depends on the plan and your actual load. Agreed with you before the switchover, it does not change afterwards without your consent.

AI handles only one step in five — always supervised.

AI as the tool, seniors in charge

Senior analysis first, AI second — then senior review, tests and adjustments. We stand behind every line.

The code belongs to you

Source code, access and documentation handed over in full on delivery.

Full transparency

A check-in every week, and a demo of your product before the test phase.

A clean, documented architecture, ready to evolve after delivery.

Frequently asked questions

What you’re probably wondering about.

Another question? Write to us — we reply within 24 working hours.

Three levers. A scope trimmed to the essentials. A senior analysis that decides what to build before the first line of code. Then AI to do the work, overseen by senior review, testing and adjustments. That cycle is what makes a fixed price in 30 days workable.

Through what comes before and after the model. The AI that writes our code is the same one everyone uses; what makes the difference is knowing what to ask of it and spotting what won’t hold up in production. That comes from experience, not from a prompt. Behind Deploy4000 is Nosytech: 22 people, more than 80 projects delivered since 2013. It’s all on nosytech.fr.

Together we scope the first version: the simplest one that proves the value of your idea. The rest becomes a roadmap, which we can continue together once that version is approved.

Up to production ready: your product is complete, tested, and running online in pre-production. All that remains is the switch-over to production, which is free and quick since it runs on the same infrastructure. If it is not included in the 30 days, it is because its timing doesn’t depend on us alone: domain, store accounts, approvals on your side.

Yes. Scoping, design, development, deployment and senior oversight are included, and the switch-over to production is free. Payment is made in three instalments: €1,000 at kick-off, €1,500 before development, €1,500 before acceptance testing. On top of that comes production hosting, a monthly service in four plans that you remain free to take elsewhere. Plus your subscriptions in your own name: domain, store accounts.

A showcase website or a landing page is a fixed price of €1,000, with the same method and the same senior oversight. A €300 deposit at the start, then €700 after the demo, before the testing phase.

You do, 100%: source code, access and documentation. No dependence on us — you carry on in-house, with us, or with the team of your choice.

Web applications and SaaS, showcase websites, e-commerce, mobile and desktop apps. If it’s a digital product, we can very likely build it — or take over and rebuild the one you already have.

Yes, and within the same €4,000 package in 30 days. Reviewing what already exists — code, hosting, data — is part of the first week’s scoping: it tells us what we keep and what we redo, and the scope is signed off just as for a new project. One condition: having all the pieces from the start, source code, access and data. If anything is missing, we tell you before the month begins. See how we take over a project.

Yes. A tool that is slow, ageing or hard to evolve gets rebuilt on sound foundations, bringing your data across. Same principle: reviewing what exists happens during scoping, within the €4,000 package in 30 days, as long as all the pieces are in place.

A 10 to 30-minute meeting every week. In the first week, we produce the project Documentation together: mock-ups, specifications and requirements document, which you approve. On Friday of week 3, we give you a demo of your product. After the final instalment, you receive the pre-production link and your access to test it on Tuesday of week 4.

A two-week warranty follows the go-live: we fix free of charge any defects against the approved Documentation. After that, ongoing support to evolve the product, or you fly on your own — it’s your call.
