Our purpose

We redesign our clients’ critical processes, turn them into AI-native systems, and run them over the long term to deliver measurable, lasting performance.

Are you facing productivity, business development or brand image challenges? We work in a methodical, structural and systemic way to make AI your competitive advantage.

Our mission

We redesign our clients’ critical processes, turn them into AI-native systems, and run them over the long term to generate the value they seek: productivity (cost, capacity, time), business opportunities (acquisition, satisfaction, retention) and brand image (visibility, awareness, e-NPS).

AI-native system: a critical operational process designed for and with AI, in order to fully harness its capabilities.

Our compass

Pourquoi nous existons. Les entreprises leaders et performantes de demain ne se contenteront pas d'utiliser l'IA. Elles seront pensées pour et avec l'IA. Elles seront AI-native.

How we create value. We unlock the full potential of AI capabilities by embedding them at the very core of what enables companies to generate value: their processes and their teams.

What we do. We put an end to fragmented work. We automate repetitive operations. We make critical operations reliable. We accelerate decision-making. We continuously enrich the core management system.

Our story

Founded in 2018 as LittleBigCode and renamed Diametral in 2026, we address a structural problem: companies’ difficulty in generating real value from their data. In eight years, we have delivered 312 projects into production in Defense, Pharma, Insurance and Retail / Luxury.

Originally a data science pure player, we now cover the entire AI value chain: process design, agentic architecture, product, analytics, governance and human experience.

Our values

Client ROI and satisfaction. We measure our success by that of our clients. Every engagement must produce visible value. Their ROI is our yardstick, their satisfaction our standard.

Progress and innovation. We put people back where they can fully express themselves — ideation, creativity, development — and harness AI for what it frees up: time, capacity, precision of execution.

People and collaboration. Technology amplifies people; it does not replace them. Our teams’ commitment, high standards and curiosity are the foundation of our collective performance.

Our ambition

We are building the first AI-native consulting firm: an organization whose critical processes are all designed for and with AI, to achieve a structurally superior level of execution.

It is our operating model, and proof that we hold ourselves to the same standard as what we build for our clients.

One single goal: to become the global leader in transforming critical processes into AI-native systems.

Our vision

Our convictions

Market-leading companies share one common trait: they make artificial intelligence the backbone of their operational architecture. Not a stack of layered solutions, but the structural foundation of their performance.

In these organizations, data flows continuously. Models inform decisions. Agents execute. Employees amplify and arbitrate. Operations are orchestrated. All with a precision and responsiveness that previous models could not deliver.

This is what we call being AI-native. This is what we build with you.

Our vision

The paradigm shift

We are moving from a world where human time was the main unit of value to a world where intelligent systems operate continuously, serving companies and their people.

This shift is redrawing the rules of competition. Companies that embark on this transformation as quickly as possible don’t just accumulate efficiency gains: they build a structural lead that is hard to close for those who have fallen behind.

Our vision

The diagnosis

Investments in AI have been massive. Operational results, however, still fall short of stated ambitions. Promising pilots that never reach production. Tools that pile up without transforming anything. Gains that struggle to consolidate at scale.

The cause is neither a lack of resources nor a lack of will. It is structural.

AI only delivers its full impact when it is embedded in the very foundations of the organization: data flows, decision-making processes, the orchestration of operations. Layered onto an existing architecture, it reveals its weaknesses as much as it amplifies them.

AI-native transformation is not an upgrade. It is a reasoned rebuild, and it demands method and commitment.

Our vision

Our answer

Process and immersive experience are our pivots. We redesign your critical processes before deploying AI in them.

The AI & Data Engines are the operational fuel: Strategy, Governance, Architecture, Applied & Gen AI, Decision Analytics, Product Delivery, Culturation & Change, Business Innovation. Each engine fulfills an irreplaceable function in the value chain.

The contract is a packaged offer. We mobilize all of these centers of excellence for every engagement.

The transformation is carried out in four stages: Design, Build, Scale, Run. Each phase has its own deliverables, KPIs and responsibilities.

Excellence is standardized. Our clients know where we stand at all times.

FAQ

Your questions, our answers

All the answers to understand our approach, how we work and what you can expect from working with us.

Who is Diametral and what is its mission?

Diametral is a consulting firm specializing in AI and data, partnering with large enterprises that want to make artificial intelligence a true structural competitive advantage.

Our mission is to redesign organizations’ critical processes, turn them into AI-native systems (designed from the outset for and with AI), and run them over the long term to generate concrete value: productivity gains, new business opportunities and a stronger brand image.

What is Diametral’s story and why did you change your name?

Founded in 2018 as LittleBigCode, the company became Diametral in 2026.
‍
This name change reflects our evolution: from a data science pure player to a firm covering the entire AI value chain (process design, agentic architecture, governance, product, analytics and human experience).
‍
In eight years, we have delivered 312 projects into production in demanding sectors such as Defense, Pharma, Insurance and Retail/Luxury. Above all, the name Diametral marks our clear positioning: we are diametrically opposed to firms that sell slides, deliver POCs that go nowhere or make promises without concrete results.

What are Diametral’s core values?

Our values rest on three strong pillars:

Client ROI and satisfaction: We measure our success solely by the real value delivered to our clients and by their satisfaction.
‍
Progress and innovation: We put people back at the heart of ideation, creativity and development, while using AI to free up time, capacity and precision.
‍
People and collaboration: AI must amplify talent, never replace it. Our teams’ commitment, high standards and curiosity are at the center of our collective performance.

What is Diametral’s ambition for the future?

Our ambition is to become the world’s first AI-native consulting firm — an organization whose critical processes are all designed for and with AI — and to establish ourselves as the global leader in transforming critical processes into intelligent systems.

We apply to ourselves what we build for our clients: a rigorous four-phase approach (Design, Build, Scale, Run) that makes it possible to move from occasional use of AI to structural, lasting integration at the heart of organizations.
