What is Crystal Knows?

Crystal Knows (also known simply as Crystal) is an innovative artificial intelligence platform that applies behavioral psychology principles to B2B sales prospecting. The tool analyzes public writing traits across the internet and LinkedIn profiles to estimate a person's personality profile according to the DISC model (Dominance, Influence, Steadiness, and Conscientiousness). Based on this analysis, it generates practical guides on how to communicate, negotiate, and sell to each specific lead.

How it works

The user installs the Crystal extension in Google Chrome. While browsing a decision-maker's profile on LinkedIn, the seller opens Crystal's sidebar plugin. The AI algorithm analyzes the prospect's profile text — word choice, sentence structure, and described experiences — and predicts which DISC category the person fits. The system displays a report indicating whether you should be formal, direct, visual, or data-focused when sending an email or giving a presentation to that lead.

Key features

• DISC Personality Mapping: Classification of leads into classic personality types with a high rate of behavioral accuracy.
• Communication Playbooks: Exact recommendations on what to do and what to avoid when speaking with the prospect (e.g., "Do not use slang", "Go straight to the data", "Use short paragraphs").
• Personalized Email Assistant: Email extension that analyzes the text you are writing to the lead in real time and suggests tone-of-voice modifications.
• Meeting Reports: Negotiation dynamics tips based on the personality compatibility between the seller and the client.

Available integrations

Crystal connects directly to the commercial prospecting routine:

• Dedicated extension for the Google Chrome browser (LinkedIn and Gmail).
• CRM systems: Salesforce, HubSpot.
• Sales engagement platforms: Outreach.

Who it is for
