MarketerZ, the French AI agency that makes AI accessible to small and mid-sized businesses
MarketerZ is a French AI agency based in Houilles, just outside Paris. We build custom virtual assistants, phone bots, automation, and enterprise AI agents for small and mid-sized businesses. Our method has stayed the same since we started the agency in 2023: understand your needs before picking a technology.
Who we are: a French AI agency near Paris
MarketerZ is a French AI agency founded in 2023. We are based in Houilles, just outside Paris, and we work with business leaders at small businesses, mid-sized companies, and large SMEs across France and Europe.
Our team combines skills in artificial intelligence, data science, and software development. We put them to work on a single goal: building AI solutions that actually run in your business, not demos that stay stuck in a lab.
Every project starts with your existing processes. We adapt to your industry, your constraints, and your tools, instead of pushing a one-size-fits-all product.
Our position: an integrator, not a single vendor
MarketerZ does not sell one piece of software to every client. We work as an AI integrator: for each project, we pick the best technologies on the market and assemble them around your needs.
This position keeps us independent. We are never required to sell you a tool just because it sits in our catalog. We recommend what fits your business, your budget, and your security requirements.
It also holds us accountable. That is why we document our technical choices and favor open building blocks that you can host on your own servers or in the cloud, whichever you prefer.
Our four-step method
We follow the same method on every project, from the first conversation to ongoing support. It keeps things concrete, with checkpoints along the way.
- Free consultation and needs audit: a 30-minute first conversation to understand your processes, your request volumes, and your priorities.
- Custom design and prototype: we design a solution for your business and show you a prototype before any final development.
- Integration, testing, and evaluation: the solution connects to your channels and existing tools, then gets tested against real cases before it goes live.
- Follow-up, reporting, and improvements: we handle maintenance, share performance reports, and evolve the solution as your business changes.
This method applies whether the project is an AI virtual assistant or a more complex enterprise AI agent.
Technologies we integrate
We do not build everything from scratch. We assemble proven technologies, chosen for their reliability and their active communities.
- Conversation channels: website, WhatsApp, Telegram, Facebook Messenger, Instagram.
- Automation and orchestration: n8n, connected to tools like HubSpot, Salesforce, Google Sheets, or Mailjet.
- Enterprise AI agents: LangGraph for orchestration, PostgreSQL with pgvector for document memory, FastAPI for interfaces, with a choice of models (Mistral, or local models through Ollama).
- Scheduling: Google Calendar and Calendly.
- Hosting: the cloud (Google Cloud, with European infrastructure where available) or your own servers, depending on your security requirements.
This list keeps evolving. We add a technology when it brings a real benefit to our clients, never to chase a trend.
Industries we work with
We work with business leaders and managers (general management, customer service, sales, operations, IT) at small businesses, mid-sized companies, and large SMEs. Our clients are based in France and across Europe.
We have already worked in the following industries: insurance, short-term rental and hospitality, e-commerce, real estate, B2B services, and manufacturing. Our HomeAssur case study, an insurer specialized in short-term rentals, shows how we work with a client over time.
We stay open to other industries, as long as your processes involve customer conversations or document handling.
Marc, our AI demo assistant
The chat widget on this site is named Marc, AI consultant at MarketerZ. He answers your questions about our services, grounded in the content published on this site.
Marc does not make up answers. When a question falls outside what he knows, he points you to a conversation with the team instead of guessing. That is the same principle we apply to the AI virtual assistants we build for our clients.
Chatting with Marc is also the fastest way to get a feel, before your first call, for what an assistant built by MarketerZ actually looks like.
