Cloud-based CRM and customer engagement suite
Freshworks provides a cloud-based suite of customer engagement and employee management software for businesses of various sizes, including modules for customer support, sales, marketing, IT service management, and HR. It works as a single SaaS platform where each module (Freshdesk, Freshsales, Freshmarketer, Freshservice, Freshteam) handles a different task and shares data across departments, with customers choosing tiered subscription plans and optionally extending functionality through a marketplace of apps. The platform combines multiple CRM and business functions on one interconnected system, rather than offering standalone tools. Its goal is to streamline customer interactions and internal processes to improve collaboration and efficiency across departments.
