Web app & SaaS : start a project of this type
Web platforms, business tools, dashboards, back offices. From authentication to payment, with the essentials for running your business.
- New project
- Project extension
- Rebuilding an existing project
Web application, website, e-commerce, mobile or desktop app — a working product delivered in one month by senior developers boosted by AI, for a single fixed price of €4,000.
New project, redesign or existing project to take over.
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.
Web platforms, business tools, dashboards, back offices. From authentication to payment, with the essentials for running your business.
Showcase websites and landing pages that convert. Fast, polished, built for search engines and mobile.
iOS and Android from a single codebase. Notifications, offline mode, store publishing included.
Native, high-performance software for macOS, Windows and Linux. For internal tooling and demanding use cases.
Online shops and marketplaces: catalogue, basket, payment, orders and back office. From the first product sold to a growing catalogue.
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.
Mobile apps published on the stores, web platforms, games: here are a few examples of Deploy4000 projects in production.

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.
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.
No six-month black box. A clear framework, weekly milestones, and visibility from the first day to the last.
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
Development starts: architecture, data model, authentication and shared services. The first user journey comes to life, deployed on an online environment.
Architecture in place·Demo environment·First working flow
The entire scope of the Documentation is developed, with screens and features integrated. On Friday, we give you a demo of your product.
Complete scope·Friday demo·Pre-production prepared
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.
Production-ready product·Code & access handed over·Handover session
A single fixed price, announced up front. What you see is what you pay — the value of a product studio, without an agency’s budget.
Paid in three instalments — €1,000 at kick-off, €1,500 before development, €1,500 before acceptance testing.
Start my projectNo commitment — a free scoping call before we start.
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.
The price depends on the plan and your actual load. Agreed with you before the switchover, it does not change afterwards without your consent.
“We don’t sell hours, we deliver a result. Senior developers analyse and design, AI speeds things up, senior developers review, test and refine — we stand behind every line.”
AI handles only one step in five — always supervised.
Senior analysis first, AI second — then senior review, tests and adjustments. We stand behind every line.
Source code, access and documentation handed over in full on delivery.
A check-in every week, and a demo of your product before the test phase.
A clean, documented architecture, ready to evolve after delivery.
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.
