Arm

Arm, founded in 1990 and employing over 9,000 people, designs the processor architectures and semiconductor intellectual property that it licenses to chipmakers. Rather than manufacturing silicon itself, the company supplies the designs on which others build chips, and its technology is present in more than 350 billion chips to date. Its compute platform spans the smallest sensors to the world's fastest supercomputers, giving the company exposure across a broad set of end markets including mobile devices, cloud data centres, artificial intelligence, autonomous vehicles, robotics and high-performance computing.

Operating through 43 offices in 21 countries, Arm works with more than 1,000 ecosystem partners - a licensing and partnership structure that underpins the distribution of its IP. Technical work covers processor architecture design, semiconductor IP licensing, energy-efficient computing, edge and cloud compute, and more recently AI compute and agentic AI. The stated focus is on making computing efficient, secure and accessible across that range of devices.

The company describes its culture as a high-trust, flexible and supportive environment, with collaboration between engineers, software developers and architects directed at complex technology problems. Arm positions itself as a leader in AI compute and energy-efficient computing, and its platform's ubiquity - from sensors to supercomputers - is the principal measure by which it characterises its scale.
