About

Unisson is building trusted AI subject-matter experts for teams that are responsible for customer deployments (technical customer success, implementation, sales engineering). Within 20 minutes, our agents learn to use any product and can be used by teams in Slack, text, or email. Our agents gather requirements and context from existing tools enabling them to handle complex tasks like customer health audits, onboarding, product administration, and custom integrations. With Unisson, customer-facing teams have 24/7 access to an AI SME, allowing them to scale and save thousands of hours.
