AI360 Index: How visible are you in AI?

The definitive ranking of FTSE350 companies across the leading AI platforms.

Why it matters

AI is changing how investors, customers and other stakeholders discover, research and form opinions about organisations. But how accurately are AI platforms representing the UK's largest companies, and which are leading the way?

Visibility

01
What it measures

How often companies appear in AI-generated responses.

Accuracy

02
What it measures

How reliably AI represents their businesses, performance and corporate narratives.

Readiness

03
What it measures

How effectively their digital presence supports AI discovery and understanding.
