Description
About Diametral
Diametral was built on one conviction: AI is not another technology wave. It is a structural shift in how companies operate, compete, and create value.
Our mission is to help organizations become AI-native. We redesign critical business processes, embed intelligence at the core of operations, and build systems where humans and AI work together at scale. The result is tangible: faster execution, stronger performance, sustainable growth, and durable competitive advantage.
We are not a traditional consulting firm, nor a conventional technology services company. Diametral exists to solve a challenge these models were not designed for: the end-to-end transformation of enterprises for the AI era.
Our approach combines strategy, data, technology, operating model, design, analytics, and long-term execution. We partner with some of the world's most ambitious organizations to move from experimentation to enterprise-wide AI adoption.
Founded from the success of LittleBigCode, established in 2018, Diametral was created in 2026 with a clear ambition: become the global reference for AI-native business transformation.
Today, we operate across Europe and the Americas, supporting multinational organizations with a scalable delivery model focused on measurable business outcomes, ROI, and operational excellence.
Joining Diametral means joining a company at a defining moment: global ambition, entrepreneurial energy, and the opportunity to shape how organizations will operate for decades to come.
You will be a great fit at Diametral if you:
- Are energized by building something ambitious from the ground up
- Believe AI will become the new operating layer of modern organizations
- Seek impact, ownership, and continuous growth
- Enjoy working in international, multicultural environments
- Want to help shape the future of work, not simply adapt to it
