About Sybill

Sybill is an AI sales assistant designed to help revenue teams close more deals by learning what actually wins and loses deals. Unlike traditional sales tools that merely record activity, Sybill builds a living context graph that maps relationships between people, products, playbooks, and deals across all channels (calls, emails, Slack, CRM). It creates institutional memory by learning from every deal outcome—won, lost, or stalled—so that best practices are never lost when a rep leaves. Sybill provides actionable judgment through features like deal inspection, forecasting, coaching, account strategy, qualification, win/loss analysis, risk detection, and competitive intelligence. It also automates execution with AI-generated meeting summaries, briefs, follow-up emails, CRM autofill, and task management. Trusted by over 850 revenue teams, Sybill offers a free tier and integrates with popular tools via API, MCP, and two-way Slack sync.
