Aix-based tech studio. We design custom AI Agents, build software and applications, support B2B teams on LinkedIn, and publish two SaaS products that industrialize what we do: Parkour for prospecting, Katapulse for content.

They trust us
Public, industrial, and B2B organizations supported by Katalyx.
We don't do everything. But what we do, we do thoroughly.
Four coherent practices that reinforce each other: tech builds the agents and your tools, LinkedIn generates opportunities, SaaS products industrialize proven practices.
AI Agents
Free up 15 hours a week.
We design AI Agents that automate your B2B workflows — qualification, monitoring, writing, reporting. Free AI audit, pilot in 6 weeks, production in 90 days.
LinkedIn B2B
From 2 to 12 qualified meetings per month per sales rep.
We build your LinkedIn meeting engine: executive copywriting, team social selling, lead generation, LinkedIn Ads. A method proven with 40+ clients across PACA.
Our SaaS
Prospect and create content at scale.
Parkour turns every LinkedIn comment into an opportunity. Katapulse writes posts in your voice, in seconds. 7-day trial, no credit card required.
Development
The software your company is missing — built to fit.
Business software, mobile apps, and rebuilds of existing projects. Complimentary technical audit, two-week sprints, 100% IP transfer.
Here's what a day looks like with and without Katalyx.
Your best sales reps spend 3 hours a day copy-pasting on LinkedIn.
Your marketing teams repeat the same briefs every month.
Your RFP files pile up — no one has time to synthesize them.
Your CFO pulls financial figures by hand.
An AI Agent qualifies 50 LinkedIn comments while you grab coffee.
Your marketing team publishes 4× faster, 100% in your brand voice.
RFP packs generate in one click from your knowledge base.
Your CFO gets a summary report every Monday morning — automatically.
We talk about what we build. With the numbers.

« 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. »
We answer before you ask.
Another question? The 15-minute flash diagnostic is built for that — no sales pitch, just an honest map of your situation.
How much does a custom AI Agent cost at Katalyx?
Our pilots start at €4,500 excl. VAT for a focused AI Agent. Once the pilot is validated, scaling costs between €1,500 and €8,000 excl. VAT per month depending on complexity, LLM call volume, and how deeply we integrate with your tools.
How quickly can we see LinkedIn results?
30 days for early signals (engagement, qualified connection requests, inbound DMs), 60 to 90 days for recurring qualified meetings. Our method favors a gradual ramp-up so we never burn the LinkedIn account.
Do you only work in Aix and Marseille?
We are based at 67 Cours Mirabeau in Aix-en-Provence, but we support clients across France remotely. PACA clients can meet in person at our offices or on site.
Can Parkour and Katapulse be used without consulting support?
Yes — both SaaS products work self-serve with a 7-day free trial and no credit card. Consulting support is recommended for teams that want to move faster or align the tool with a broader strategy.
How do you protect our data?
European infrastructure (OVH, Scaleway), AI models hosted in Europe whenever possible (Mistral). Full GDPR commitment, a signed DPA on every engagement, and no client data used to train third-party models.
15 minutes to see what AI changes for you.
No pitch, no corporate deck. We look at one of your workflows together and tell you honestly whether an AI Agent can transform it — and what it costs.
