Why · Our vision

Become the reference partner for traditional SMEs that want to remain in control of their digital transformation.

Traditional industries — manufacturing, precision craftsmanship, professional services, food processing, aerospace and maritime — are undergoing their biggest change since the arrival of the Internet. Digital transformation and AI are reshaping production, customer relationships and required skills. SMEs that do not adapt their technology stack within 24 months risk losing 30 to 50% of their margin to augmented competitors. This is not an opinion. It is a 2025 McKinsey finding confirmed by our field experience.

Yet most industrial SME leaders do not have the resources to absorb this transformation on their own. No CTO. No CMO. No digital department. They built their companies on operational excellence, not on mastering technology. Traditional consultancies are too expensive, too slow and too disconnected. Digital agencies are too superficial, too focused on e-commerce or consumer communication. No one truly serves them.

Our vision: to be the firm they have been missing. A partner that understands their traditional business, speaks their operational language, and puts technology at their service — not the other way around. We believe French industrial SMEs have everything they need to become global sector leaders if they digitize intelligently. Our role is to help them get there, concretely and at their own pace.

How · Our mission

Help SME leaders embrace change — not complexity.

Our role is not to sell tools. It is to help you gain time, margin and confidence so you can ultimately lead your transformation yourself. No dependency. Real transfer.

    Enguerrand Boulnois

    Founder · Strategy and vision

    Enguerrand founded Katalyx with one conviction: French industrial SMEs need a partner who speaks their language, not that of Parisian consultancies. After 10 years in a high-tech industry — aerospace — working on industrial companies' digital transformation and three years in applied AI, he leads Katalyx's vision, strategic client relationships and high-stakes engagements. He personally leads client steering meetings to define the products they need.

How we work together

Three partners, three roles, one triad clients see at every stage.

On every Katalyx engagement, all three partners intervene at specific moments. No engagement depends on just one of us. It is our best guarantee of continuity.

Katalyx non-negotiables

Five values we put into contracts. Not just on a wall poster.

  • 01

    Radical honesty

    We tell you what works and what does not. We decline an engagement when we are not the right provider. We direct you to a peer when needed.

  • 02

    Commitment to results

    Fixed prices, never open-ended time and materials. A firm timeline, approved by everyone. Firm deliverables, validated by the sponsor. If a deliverable does not arrive, you do not pay for it.

  • 03

    Operational transparency

    Transparent monthly reporting. Access to our engagement management tool. Full visibility on hours used. You know what you pay for and why.

  • 04

    Skills transfer

    Your teams become autonomous within six months. We document everything. We train your people. At any time, you can replace us or bring the work in house.

  • 05

    Sovereignty and compliance

    Your data stays in the EU. A sovereign stack on request. GDPR and the AI Act integrated from scoping. No reuse of your data by third parties.

Katalyx contractual commitment

These five values are included in every Katalyx client contract. In the event of a proven breach, you can terminate without penalty. It is written in black and white.

What truly sets us apart

Three things none of our competitors do. Not three slogans: three concrete commitments.

  • 01

    We come to you, not the other way around.

    We travel to you for strategic meetings: audits, kickoffs, leadership debriefs and training. No pressure to come to Paris. Our main operating territory is South-East France (Aix-Marseille, Toulon, Avignon, Nice and Lyon). We work with all of France by video. In-person elsewhere: a transparent travel allowance.

  • 02

    We train your team alongside the engagement.

    Every Katalyx engagement includes skills transfer. At the end of the project, your teams know how to operate the delivered solution. No French firm of our size does this by default — most lock clients in through technical dependency. We keep the exit open.

  • 03

    We commit to our method in the contract.

    Fixed price. Fixed timeline. Fixed deliverables. The five Katalyx values are included in black and white in every contract. In the event of a proven breach, you can terminate without penalty.

Our final commitment

If you reach the end of this page unconvinced, we are not the right partner for you. That is fine. We would rather point you elsewhere now than disappoint you in six months. It is exactly what we will say in the first meeting.

How Katalyx began

Katalyx was born from a shared observation: industrial SMEs lack a serious partner.

Before Katalyx, each of us had observed the same thing from our own path: French industrial SMEs have a real opportunity with AI and digital transformation, yet nobody supports them seriously. Major consultancies do not take on engagements below €1 million. Digital agencies do communications and e-commerce, not AI applied to production. IT service firms deliver code, not transformation.

We met during our respective entrepreneurial journeys. Very quickly, the evidence was clear: our skills were complementary, our observation was shared, and our ambition was aligned. We wanted to build the firm that would have helped us if we had led an industrial SME five years earlier.

Katalyx has officially existed since March 2025. Since then, we have supported several industrial SMEs and startups, from five-day strategic audits to 18-month transformation programmes and software development. We are based in Aix-en-Provence and Marseille, but 50% of our clients are outside the region — proof that quality outweighs geographical proximity when the method is solid.

    « Très belle collaboration avec l'équipe Katalyx sur le développement d'iZola. Projet exigeant techniquement (KYC biométrique, signature électronique, scoring), tenue des délais, qualité du code, et surtout un vrai dialogue produit du début à la fin. Un mot pour Victor, notre chef de projet : disponibilité, rigueur, écoute, et cette capacité rare à anticiper les sujets avant qu'ils deviennent des problèmes. Une vraie différence sur un projet de cette ampleur. Merci à toute l'équipe — on continue l'aventure ensemble. À recommander. »

    « J’ai eu l’occasion d’échanger à plusieurs reprises avec Enguerrand dans un cadre entrepreneurial. Ce qui m’a marqué, c’est sa capacité à penser “stratégie” avant d’agir, à chercher des solutions concrètes plutôt que des promesses. Son approche est jeune, mais déjà structurée et tournée vers le développement de solutions qui font sens pour les entrepreneurs. Un bel état d’esprit, beaucoup de clarté et une vraie orientation résultat. »

FAQ · About

Seven questions before we meet.

Questions industrial SME leaders ask before contacting us. If yours is not listed, write to us: Enguerrand replies personally within one business day.

  • How long has Katalyx existed?

    Katalyx has officially existed since March 2025. Our three partners had already worked together on joint engagements since 2023. The company was formed to structure that collaboration and make it accessible to industrial SMEs.

  • How many people are at Katalyx?

    Three full-time partners. An extended team of five to ten senior freelance consultants and partners — designers, developers and AI legal specialists — is activated depending on the engagement. No juniors. No interns. No delivery pyramid.

  • Who do you typically work with?

    Industrial SMEs and mid-sized companies, primarily based in France. Teams of 10 to 1,500 employees. Revenue from €1 million to €300 million. Key sectors: manufacturing, food processing, professional services, biotech, energy, construction, maritime and aerospace. Some of our clients are technology scale-ups building AI SaaS products.

  • Do you work with pre-seed startups?

    Our method is designed for SMEs and mid-sized companies with a clear opportunity and the capacity to experiment without putting everything at risk. For pre-seed startups, we offer a lighter format: a two-hour workshop for €1,800 excl. VAT, or occasional product coaching. For AI SaaS scale-ups with a tested MVP, we offer our AI SaaS development package at a fixed fee or in an equity-friendly format.

  • What happens in a first conversation?

    Contact us through the contact form, by email at enguerrand@katalyx.fr, or via LinkedIn. Enguerrand replies personally within one business day. A free, no-obligation 30-minute first meeting is offered within seven days. You leave with three prioritized options and a candid view on whether working together makes sense.

  • Are you Qualiopi certified for training?

    Yes. Qualiopi certification was obtained in 2024 and renewed annually. Our activity declaration number is available on request. Our AI training is eligible for OPCO funding through partners, FNE-Formation, and Bpifrance / France 2030 AI grants.

  • What geographic area do you cover?

    We work in person primarily across the South-East — Aix-Marseille, Toulon, Avignon, Nice and Montpellier — with travel included up to 100 km from Aix. Lyon and Paris: one meeting per quarter included, then charged at cost. Rest of France: transparent at-cost travel. Video calls are available everywhere at no extra cost.
