We support Digital, Marketing & IT departments in transforming their digital ecosystem into a lever for commercial and operational efficiency.



Our role: to frame, structure, design, optimize.



Concretely, our support is based on four phases:

1. Analyze and frame the project, to clarify the use cases, align stakeholders, and prioritize all their needs as well as the right performance indicators.

2. Structure the solution architecture, by modeling customer and business journeys, data flows, and defining the specific ergonomic and technical architecture.

3. Design tailor-made interconnected solutions:


• Product sites & order portals


• Customer & network spaces


• Product configurators & calculators


• Business & field tools (Technician, Sales Admin, HR, After-sales Service, Sales)

4. Continuously test, maintain, and improve, by sustainably evolving these services through various optimizations (UX, technical, CRO, accessibility) and reasoned AI implementations.



The result: better-equipped teams, loyal customers, and a fully mastered distribution network.

Ultimately,

Adeliom becomes a true extension of their team, aligning the IS with the reality of businesses and customers to put technology back at the service of the Humans who use it.

• Innovation Tax Credit with NetDevices

Thanks to its CII accreditation (innovation tax credit), NetDevices offers its clients the possibility of obtaining a 30% saving on expenses incurred. The objective is to reduce the financial impact of innovative projects. Accreditation also assures you that we have the necessary human and material resources to carry out the operations entrusted to us.

• Methodology

The agency organizes innovative solutions to support you in the development of your digital strategy, carry out a digital transformation project or evolve your organization towards AGILE methodologies.
In addition to our technical expertise, our international multidisciplinary team assists/advises on UX/UI design, functionalities, Business Plan aspects, and commercial models. It works with the most efficient tools of the moment and guarantees you a tailor-made result. It has adapted to diverse and specific objectives.

• The birth of the Parisian web agency, Netdevices, expert in Web, Mobile, Cloud & Data

Initially, our ambition was to create a "spotify" for paid daily press. The project aimed to offer internet users the possibility to find all articles from multi-title "print" newspapers on a single platform. And this, at attractive prices for the general public, with less intrusive advertising. To this end, we used semantic analysis and language analysis tools to suggest associated content.
This project also had the following objective: the construction of a tablet dedicated to reading journalistic content. This hardware project explains the company name Net (for internet) Devices (for the project's hardware). We were incubated at ENSAM, which supported us on the industrial side. The dedicated hardware and environment were prototyped.

As press publishers abandoned the project 18 months later, efforts were focused on Research & Development. NetDevices redirected its activity towards service provision, while continuing to invest in R&D with the launch of the Web2Mobile and Sharry solutions.

With over 10 years of experience, our clients benefit from all our expertise in implementing web, mobile, cloud deployment, data lake implementation, and artificial intelligence algorithm integration (computer vision, natural language processing) digital solutions.

• MVP Studio Offer

Many clients come to us with projects whose scope is yet to be defined, whose functionalities will evolve quickly, and whose interfaces are not finalized. Rather than engaging in direct JS development, we now have the capability to develop your project quickly and under highly adapted financial conditions.
With bubble.io, we meet this need: to be hyper-responsive with enhanced agility without requiring the traditional investments to launch a product/project.

In 2021, we therefore launched the MVP Studio offer:

- Upstream support on product definition and positioning

- Record-time development of your product

- Coaching on commercial aspects, revenue model, positioning, Business Plan realization, and assistance with the approach for financing from entities such as BPI.

• Complex Platforms

As an expert in web, mobile, cloud, and data, NetDevices handles all types of projects, even the most complex ones.

Do you need an iOS or Android application for your sales team, to showcase a product, to collect customer feedback, or to manage your employees' interventions, a website redesign or creation? Write to us.

Thanks to our expertise and tools, we provide you with a scalable and evolving result.

Our specializations include:

- JavaScript frameworks: reactJS, NodeJS, React Native, Angular, VueJS, Flutter, etc. We add associated JavaScript libraries.

- Automated testing: jest, mocha, jasmine…

- Quality and monitoring: datadog or prometheus, sonarqube.

• Big Data

Today, to grow, companies cannot escape Big Data. Data collection allows you to improve your commercial operations (understanding your target audience, their expectations, etc.), but also to gain overall efficiency. So, to help companies optimally exploit data, NetDevices uses several Big Data solutions at your service.

- Datalake: allows you to store your data.

- Python: it is a web language specifically adapted for big data. It allows transforming large data formats. It is essential assistance for developers.

- Computer Vision: thanks to this artificial intelligence, you can analyze your data to facilitate decision-making.

• No code

Creating a website requires specific coding skills. However, not all companies have the ability to use the services of a programmer or developer for the creation or development of their website.
NetDevices provides you with several no-code software solutions: bubble.io, Wimpact projects, FrigoGusto, Pairing.
Very easy to use, these web solutions allow you to modify the components of your Web/Mobile application as you wish. Use drag-and-drop, and your web project takes shape.
