Corunner is an AI-powered business operating system designed to coordinate work across the tools a team already uses. Rather than requiring a new app or workflow, it operates within Slack, Microsoft Teams, Google Chat, and email, connecting information across business systems and helping teams move tasks forward. Its platform is described as an organizational intelligence layer that remembers decisions, workflows, terminology, and ownership, building context over time.

Corunner offers AI specialists for tasks such as answering questions, summarizing conversations, scheduling, running stand-ups, filing tickets, managing projects, and identifying risks or dependencies. It can reason across connected tools, including CRM, project management, documentation, code, support, and data platforms; the company lists integrations such as Salesforce, HubSpot, Jira, Linear, Notion, GitHub, Zendesk, Intercom, and Snowflake, with more than 50 connectors. The system can propose actions and carry them out with human approval, while inheriting existing permissions. It also supports visual reasoning, allowing teams to share screenshots, diagrams, documents, or mockups in conversations and receive analysis and suggested next steps.
