# Unisson

> Unisson (YC W26) builds AI agents that act as subject-matter experts for B2B software implementation and customer-facing teams. Runner executes deployment, onboarding, and administration tasks inside a product; Explorer maintains a live knowledge base of how the product works. A bearer-token REST API at api.unisson.ai exposes agents, runs, skills, knowledge base, integrations, and an external Runner API for third-party tools.
