What we use

Stack or Software,
Languages, Models, Infrastructure.

Languages & Frameworks are the building blocks used to code the product.
AI Models & Data are the intelligence layer that processes, generates, and analyzes information.
Infrastructure & DevOps are the underlying environment where everything runs and scales.
Software & Workflows are the tools and integrations that connect business operations, automation, and support.

Those four layers fit together.

AI models & engineering

Models change every few months, so we treat them as replaceable parts. What lasts is the engineering around them. Retrieval grounds every answer in knowledge the client controls. Agents carry tasks across systems. Evaluation checks the answers before release. Private hosting keeps sensitive data in-house.

Automation & workplace

This is the core of breinz. Operations run on processes that repeat by the hundred: reading documents and emails, retyping data between systems, checking it and passing it on. We automate them from start to finish on top of the systems a company already runs, legacy included. Results arrive by email, chat or shared documents, and people approve at the points that need a decision.

Marketing & sales

We automate the cycle: campaigns across search, social and AI assistants, content production, email sequences, reporting, brand monitoring, lead research and qualification. AI turns one brief into images, voice-overs and videos. The team sets strategy, message and budget.

Customer care

Helpdesk platforms hold tickets, conversation history and the knowledge base. Messaging APIs add WhatsApp, SMS and voice as channels. We connect language models to both: incoming messages are classified and routed, replies are drafted from the knowledge base, and each exchange is logged back into the helpdesk.

  • LiveChat

E-commerce & business systems

Store platforms, marketplace APIs and a multichannel order hub hold the sales side: products, prices, stock and orders. Accounting systems hold the books. We connect both sides and automate what runs between them: product listings and descriptions across marketplaces and languages, price and stock updates, order processing, returns and invoicing. Invoices follow local rules, national e-invoicing systems included. Sales history feeds demand forecasts.

Project management

Coordination is the hidden cost of delivery: reminders, dependency checks, workload balancing, documentation that has to stay current. We automate that coordination inside the planning tools the team already runs, and control stays with the project manager. Shared whiteboards hold the process maps that come before automation.

Data, engineering & cloud

Automation needs clean, connected information. Databases store the history. Transformation and scheduling tools keep it consistent and fresh. Dashboards and forecasting engines turn it into decisions. Custom code covers the steps between ready-made tools and runs on AWS, Azure, OVHcloud or your local hosting provider. Your choice.
