Zendesk

Zendesk is a leading customer service and support platform used by over 100,000 companies worldwide to manage customer interactions across email, chat, phone, and social media. Founded in 2007 in Copenhagen (now headquartered in San Francisco), Zendesk pioneered the modern help desk software category. The platform's ticketing system organizes all customer requests in one place with intelligent routing, SLA management, and automation rules. Zendesk Suite combines the full stack: Support (ticketing), Talk (phone), Chat (live chat), Guide (knowledge base/help center), and Explore (analytics). AI features including Zendesk AI copilot can automatically categorize tickets, suggest responses, and resolve simple queries without human intervention. The platform's marketplace has 1,500+ integrations including Salesforce, Slack, Shopify, and JIRA. Zendesk is the choice for mid-market and enterprise companies that need sophisticated support operations. Suite Team starts at $55/agent/month and Suite Professional at $115/agent/month — pricing that smaller businesses often find steep, driving interest in alternatives like Freshdesk and Intercom.
