ChurnZero

ChurnZero is a Washington, D.C. customer success platform that combines account health scores, in-app engagement, and a set of AI agents, including the Kit assistant launched in October 2026, for subscription software teams.

7.5/10
Overall Score
Recommend

ChurnZero is a strong fit for mid-market SaaS customer success teams that want health scoring, playbooks, and AI help in one CS-only platform.

Best for

Customer success teams of 5 to 50 people at subscription software companies that want health scores, automated plays, in-app messages, and renewal forecasting, with AI agents that draft outreach and flag risk.

Not ideal for

Very small teams that want a self-serve plan with a published price, and companies that want customer success built into their CRM.

Verdict

ChurnZero has built one of the deepest CS-only products in the field, with ChurnScores, in-app walkthroughs, renewal forecasting, and a growing set of named AI agents. The Kit assistant, launched in October 2026, answers account questions and drafts emails in each user's writing style. Pricing is not published, and the platform takes real setup work. For mid-market CS teams, it is an easy recommendation.

Who Uses ChurnZero, Where It Fits on Price, and Its Competitors

ChurnZero sells to subscription software and services companies whose customer success teams own renewals, adoption, and expansion. Most use it for a 360-degree account view, health and relationship scores, automated plays, in-app announcements and walkthroughs, and renewal forecasting. Its AI agents track stakeholder changes, customer tone, buying intent, and relationship risk, and Kit lets a manager ask which accounts need attention this week. ChurnZero was founded in 2015, raised a $25 million Series B in 2021, and has about 143 employees.

On price, ChurnZero quotes every deal after a demo. Its closest competitors are Vitally, ClientSuccess, Planhat, and Custify.

Pricing

We checked ChurnZero's website and found no public price list. ChurnZero quotes each plan after a demo, and the AI agents are sold in packages such as Agentic Essentials.
