Companies today are increasingly providing Support - both internally and externally - on Slack and Teams. The ad-hoc use of triage channels and customer Slack rooms creates problems of missed responses, lack of service metrics and anxiety for all the responders who individually keep scanning Slack rooms. ClearFeed converts Slack channels into a single queue of requests, uses AI to flag requests that need a response, allows responders to update status of requests and assign ownership and make sure all requests are closed out. Integrations with tools like Zendesk, Jira, Freshdesk, Salesforce et al allow agents to convert or link Slack requests to other enterprise tools and close the loop back on Slack when issues are solved therein. We have been helping the world's leading companies like Atlan Data, Accryl, Chronosphere, Benlabs, Sprinto, MindsDB, TestRigor in scaling customer support, engineering escalations and IT helpdesk on Slack. We are founded by a team of second-time entrepreneurs who previously worked at companies like Facebook, Amazon and Qubole. Our small team of engineers, data scientists and product managers is based out of India. We are backed by Sequoia Surge, 8VC and leading angels..
