FirstQuadrant
AI sales platform for B2B teams with human-in-the-loop
FirstQuadrant is an AI sales execution platform that helps founders and revenue teams move faster, stay organized, and close more deals by streamlining behind-the-scenes sales work. The platform encompasses a complete suite of AI tools organized around three pillars: Grow for top-of-funnel expansion through personalized email campaigns, Convert for pipeline management and deal optimization, and Nurture for relationship management and reactivation of inactive prospects.
The platform features advanced AI reasoning to keep deals moving—understanding context, thinking ahead, and supporting reps with the right next steps. Key capabilities include AI Conversations, AI Actions, AI Enrichment, and AI Campaigns, enabling teams to convert more deals, nurture inactive relationships, and grow their pipeline. In June 2024, FirstQuadrant acquired Flike, another AI-powered sales tool, to expand its capabilities.
Backed by Y Combinator (S21) and recognized as #1 Product of the Day on Product Hunt, FirstQuadrant was used by the fastest-growing YC startups. In 2025, the company completed a confidential agreement with a leading AI technology company that recognized long-term strategic value in components of the FirstQuadrant platform and data infrastructure.
