Close is a sales CRM with built-in calling, SMS, email, automation, and AI, designed for founders, startups, agencies, and growing sales teams. The platform helps businesses manage leads, communicate with prospects, track opportunities, and automate follow-up from a single system. Close is commonly used by teams that want their CRM to support sales execution, not just store customer data. Users can call, email, text, manage pipelines, assign tasks, create workflows, run outreach sequences, and track sales activity directly inside the platform.
