With you, by your side.

Artificial intelligence is establishing itself as the new standard of universal competence, a common good whose speed, precision, and creativity saturate our realities. Yet, a major paradox defines our era: the barriers of knowledge are collapsing while the frontiers of the tangible are hardening. The embodiment of ideas into viable, sovereign, and lasting physical objects constitutes a true generational challenge. Faced with this proliferation of the virtual and automation, one question remains: who will master the art of meaningful and sensitive creation tomorrow?

Expertise: Bringing Your Projects to Life

To address the urgency of embodiment, WITH—BY— tackles the subject head-on and offers support ranging from initial concept to commercial deployment of your future product. Our methodology is built around four critical phases, designed to control costs and lock down each step of industrial development.

01

Align the idea with market reality

The journey begins with an essential framing and feasibility phase to compare your vision with technical and economic constraints. Here, we define the core functionalities and ergonomics of the product, while outlining a technical architecture based first on the selection of existing components to limit research and development costs, and then on the identification of custom elements.

02

Validate the function through the material

Once these foundations have been consolidated, we move on to the Prototype stage to bring the idea to life. Here, technical efficiency takes precedence over aesthetics: the objective is to validate functionality under real conditions. Our teams design, develop, and manufacture a first version of the product necessary to validate physical footprint and use cases.

03

Secure the transition to mass production

The transition to Product marks the most technical stage: mass production. This phase includes optimizing designs for reliable large-scale manufacturing, negotiating with suppliers to secure your margins on target volumes, and a preliminary conformity study to European standards to remove any regulatory barriers.

04

Turn innovation into revenue

Finally, the Commercialization phase ensures the product's entry into our e-commerce ecosystem. We prepare the product listing for our online store and orchestrate logistics, from storage to shipping processes. The initial stock build-up and its financing method are then jointly studied, allowing the project to reach its audience and generate its first revenues in a structured manner.

E-commerce: Offering Unique Products

with-by.com is an online store, our digital showroom, a space for expression for WITH—BY— and its creative and technical ecosystem. Here, we showcase our original products as well as the fruits of our collaborations and partnerships. This window into our brand offers a glimpse into the foundations of our approach, provides access to the technical documentation sought by our specifiers, and relays our questions on the themes that drive us.

01

Original products WITH—BY—

Designed, developed, and manufactured in France in our Parisian and Rouen workshops, our original products embody a committed vision of technology. From engineering to industrial design, including user experience and ergonomics, our solutions create a world of collective, immersive, and narrative experiences. Our firm commitment to controlling our environmental impact requires our products to be repairable, durable, and modular, without compromising their performance and functionality.

02

Partnership or collaboration products

Because innovation thrives on dialogue, we are opening our ecosystem to individuals who excel in their field, whether or not they are associated with a company, brand, institution, or other collective. These exchanges can lead to partnerships, collaborations, or publishing projects.

WITH… BY… : Highlighting our collaborations

The success of a technological product relies on a perfect symbiosis between market vision and industrial mastery. This is why we position ourselves as a creative and technical partner, committed to working alongside you. Our model is based on a principle of absolute transparency regarding ownership and value distribution.

01

Balanced and secure intellectual property

We believe in a healthy division that protects each party. Your identity remains yours: the idea, the original concept, the specific functionalities, and your entire brand universe are yours without reservation.

For our part, we retain ownership of our hardware and software engineering, which constitutes our unique expertise. However, this expertise is at the service of your success: we grant you an exclusive operating license for the design and software for your product. You thus have the absolute right to commercialize and promote your innovation, while also benefiting from the possibility, eventually, of acquiring total industrial independence if you so wish.

02

A turnkey production and distribution infrastructure

To allow you to focus on growing your brand, WITH—BY— handles operational complexity. We manage the entire chain after the development phase: from storage to online sales, all the way to shipping and first-level after-sales service.

Our business model prioritizes shared success. Once the product is launched, revenues are distributed according to a clear structure, where the majority of the generated turnover goes directly to you. This approach enables sound cash flow management, with sales naturally funding the production of subsequent batches.

03

A sustainable growth cycle

As manufacturers, we continuously monitor your stock levels. As soon as a critical threshold is reached, we plan replenishment together to avoid any disruption in commercialization. This virtuous cycle ensures service continuity and a gradual ramp-up of your activity, without the usual logistical friction. By entrusting your project to WITH—BY—, you are not just purchasing technical development; you are integrating an ecosystem designed to transform an innovation into lasting commercial success.

A New Industrial Vision

The time for imitation is over. While past decades saw Europe importing its technological standards, today we choose to forge a new French industrial vision. We are working to foster the creative genius of local talent with a view to regaining sovereignty. We refuse to base our ambitions on saturated foreign models and we are freeing ourselves from the burdens inherited from the last century. Already ranked fourth globally in industrial investments over the past five years, France is proving that it has more than ever the resources to inspire the world through the excellence of its achievements. Let us restore our industrial base, and decide to build and shine. This ambition is becoming a strategic necessity for anyone who wishes to innovate with agility and ecological awareness. WITH—BY— aims to bring together entrepreneurs, engineers, and creators around its future projects. Tomorrow's world will not be content with ideas circulating on screens; it will take shape in our territories through our material know-how.
