Bring us the hard problem.

We design and build data and AI systems that scale and stay under your control.

Agnostic is a French engineering firm specialised in advanced software, data infrastructure and artificial intelligence. We help organisations solve hard technical problems with systems that are sovereign, fast and built to last.

What we build

Three disciplines, practised by one team, so that the model, the data beneath it and the software around it are designed together.

Artificial intelligence & agents

We design and build intelligent applications powered by state-of-the-art AI models.

  • Generative AI, LLMs and agentic systems
  • Autonomous AI agents and orchestration
  • Private AI inference and model optimisation
  • RAG, knowledge systems and enterprise AI integration

Data engineering & infrastructure

We lay the foundations that turn complex data into reliable, usable intelligence.

  • Data platforms, pipelines and architecture
  • Real-time processing and high-performance systems
  • Scalable cloud, hybrid and on-premises infrastructure
  • Data integration, governance and reliability

Advanced software engineering

We build robust, fast software for demanding environments.

  • Custom platforms, APIs and enterprise applications
  • Systems engineering and Rust development
  • High-performance backends and distributed systems
  • Architecture, modernisation and technical leadership

Your data, your infrastructure, your control.

We design solutions with privacy and security at the core of their architecture, including private and on-premises deployments.

We build our own tools

Our advice comes from practice. Alongside client work, we develop our own inference and agent software, and we apply what we learn there to the systems we build for you.

Lisa

Inference engine for Apple Silicon

Lisa runs open-weight models locally, on hardware you own. With parallel speculative decoding, it generates 2.7 to 3.8 times faster than standard decoding in our tests.

Chad

A minimal AI agent

Chad is our own take on an agent: let the model do what it is already good at, and keep the infrastructure around it as lean as possible.

Leadership

Every engagement is led by a founder, who serves as its architect and directs the engineering team from the first workshop to production.

From discovery to scale

We combine the speed and adaptability of a specialised engineering team with the technical rigour that critical systems demand. Our approach is pragmatic, collaborative and focused on results.

  1. Discovery

    We map your goals, your data and your constraints.

  2. Architecture

    We design the system and choose the technology with you.

  3. Development

    We build in short iterations on production-grade foundations.

  4. Deployment

    We ship to your environment: cloud, hybrid or on-premises.

  5. Scaling

    We optimise and evolve the system as usage grows.
