ListKit’s company filters are powered by deep website crawling, enrichment, and AI analysis across millions of businesses. These filters help you quickly narrow down companies that actually fit your ICP — not just by surface-level firmographics, but by how companies operate, grow, and position themselves.
This guide explains what each filter means, when to use it, and how to combine them for outbound campaigns that convert.
AI Score
What it is
AI Score measures how strongly a company is focused on artificial intelligence based on real signals from their website, product pages, features, and technology stack.
This includes:
AI-powered product features
Mentions of AI, automation, machine learning, or LLMs
AI-first positioning or messaging
How to use it
High: AI-native or AI-first companies
Medium: AI-enabled or experimenting with AI
Low: Little to no AI focus
When to use it
Selling AI tools, automation software, or data platforms
Targeting buyers who already understand AI and don’t need education
Example
Selling AI sales tools → Filter for AI Score labeled Medium or High
