What We Do

At Unthread, we’re solving an evolving, yet pervasive, challenge:
support is broken . The way customer support teams and internal teams like IT, HR, and Operations manage workflows has failed to keep up with modern business needs—especially for teams living in Slack .

We’re here to change that. By deeply integrating with Slack and leveraging AI-powered automations , Unthread helps teams bring order to the chaos of support conversations—whether it’s managing external tickets or internal IT or HR requests . We don’t just automate repetitive tasks; we structure workflows, enabling teams to focus on solving real problems efficiently.

Today, forward-thinking companies like Langchain ,
Apollo GraphQL ,
Hub Spot ,
Lemonade , and Automattic all rely on Unthread to ensure their support runs smoothly, both inside and outside their organizations.

Joining Unthread means jumping in at exactly the right time . We’ve already hit product-market fit , built a lineup of incredible clients, and are positioned for rapid growth across both internal and external support ecosystems —spaces desperately in need of innovation.
