Close is a customer relationship management platform designed for inside sales and high-velocity outbound teams, with communication tools built directly into the CRM rather than added through integrations. Every lead record shows a single timeline of calls, emails, and text messages, and reps can call or text from within Close using its built-in phone system, including a power dialer that works through a list automatically and a predictive dialer that places multiple calls at once and connects a rep when someone answers. On top of that, Close provides pipeline and opportunity management, email sequences with automated follow-up, workflow automation that assigns leads and triggers tasks as deals move stages, reporting on activity and conversion, and, more recently, AI features that summarize leads and turn natural-language questions into filtered lists. It is aimed at small and mid-sized sales teams, typically under a hundred reps, that care about speed to lead and call volume and do not want to buy and connect a separate dialer, sequencing tool, and CRM. Close is sold as a paid subscription per user with tiers that unlock automation, more phone features, and higher usage limits, and it offers a free trial rather than a permanent free plan.
