Overview
How each tool is described
Warmly
What is Warmly?
Warmly is a go-to-market intelligence platform that helps B2B sales and marketing teams identify website visitors, understand account activity, and create targeted revenue workflows. It combines website visitor identification, buyer intent signals, enrichment data, and AI-assisted engagement tools to help teams discover potential opportunities from anonymous website traffic.
- Website visitor intelligence: Warmly identifies companies and potential buyers visiting a website, helping revenue teams understand which accounts are showing interest beyond traditional form submissions.
- Intent and account signals: the platform analyzes visitor behavior, company information, and engagement signals to help teams prioritize accounts that may be more likely to enter a sales conversation.
- AI-assisted prospect engagement: Warmly provides AI-driven workflows that help teams engage website visitors, qualify inbound interest, and support personalized outreach based on available account context.
- Revenue workflow integration: teams can connect visitor insights with existing sales and marketing processes, including CRM and go-to-market tools, to help activate identified opportunities.
Warmly is most suitable for B2B revenue teams that want to turn anonymous website activity into actionable sales intelligence and improve how they identify and respond to high-intent prospects.
6sense
What is 6sense?
6sense is a B2B go-to-market intelligence platform that combines first-party and third-party buying signals, account identification, predictive analytics, advertising, sales intelligence, and workflow automation. It is designed to help revenue teams identify which accounts are researching relevant solutions, understand where they are in the buying journey, and activate that intelligence across marketing and sales.
- Buyer intelligence: 6sense combines a company's first-party CRM, marketing-automation, website, and product signals with its Signalverse intent network and third-party data. It resolves those signals to accounts and buying groups, helping teams see research activity, relevant keywords, web engagement, and other indicators of purchase intent that occur before a prospect identifies themselves directly.
- Predictive prioritization: 6sense's predictive models use each customer's historical opportunity data alongside firmographic, technographic, behavioral, CRM, MAP, web, and intent signals. Outputs include account profile-fit scores, intent scores, predictive buying stages from Target through Purchase, and 6sense Qualified Accounts (6QAs), helping teams prioritize accounts based on both suitability and current buying behavior.
- Activation and advertising: Audience Builder creates dynamic segments using criteria such as buying stage, profile fit, keyword research, campaign engagement, and web activity. Intelligent Workflows can then use decision logic and action nodes to activate those audiences across 6sense Advertising and connected systems such as Google Ads, LinkedIn, Meta, CRM, marketing-automation, and sales-engagement platforms.
- AI and agent workflows: RevvyAI provides a conversational interface for exploring account data, advertising performance, website activity, intent signals, reporting, and other go-to-market information, and can perform selected actions from the conversation. The 6sense MCP Server extends account intelligence, predictive buying stages, 6QA status, keyword intent, campaign performance, and newer people and enrichment capabilities to approved MCP-compatible AI agents such as ChatGPT, Claude, Writer, Agentforce, and Copilot.
6sense is most relevant to B2B organizations with enough first-party history and coordinated sales and marketing operations to act on account-level buying signals. Its value depends on data quality, target-market definition, predictive-model readiness, integration coverage, and whether teams consistently convert identified buying activity into advertising, nurture, and sales engagement.
