Our verdict
Intercom is the premium choice for startups that want proactive, AI-powered customer engagement — and their startup program makes it affordable in year one. Zendesk is the best option for teams that need mature ticketing, phone support, and enterprise-grade SLAs. Crisp is the scrappy underdog: incredibly affordable for small teams, with a surprisingly capable feature set including video calls. Start with Crisp if you're bootstrapped, Intercom if you're funded, and Zendesk if support is a core business differentiator.
