How B2B brands show up to buyers and AI

For B2B buyers, discovery no longer happens in one place. Buyers still build shortlists through memory, trust, and peer signals. And now AI systems shape what buyers see first. The TOM Index, research and methodology by StudioNorth, ranks brands on both: Top of Mind and Top of Model.

What a TOM Score measures

Every TOM Score combines buyer visibility and AI visibility inside a defined industry category.

top of mind

Top of Mind

How clearly a brand lives in buyer memory, category conversations, peer validation, and public market signals.

top of model

Top of Model

How accurately AI systems surface, summarize, compare, and describe the brand inside buying-context prompts.

Top of Mind still matters. Top of Model is now the dimension that AI shapes.

How a TOM Score is built

Each TOM Score is a composite of two underlying scores

top of mind

Audience Visibility Score (Top of Mind)

How clearly people perceive, understand, and trust the brand. Synthetic audience intelligence models how target buyers perceive a brand, using independent research into the signals that shape human judgment. Components: Distinctiveness, Clarity, Trust, Resonance, and Confidence.

top of model

LLM Visibility Score (Top of Model)

How effectively AI systems discover, interpret, and evaluate the brand. It draws on research into how those systems surface, summarize, and compare brands. Components: Category Discovery, Persona Discovery, and Executive Voice.

Every TOM Score reflects how a brand shows up in the real buying landscape today.
