“We basically have two timelines in our company: pre-Idiomatic (not useful) and post-Idiomatic (what everyone uses).”


Routing tickets based on user self-selection lacked the precision needed to specialize agents. With over 4 million monthly contacts, Instacart’s Customer Support team needed a way to optimize efficiency while improving the support experience. Instacart’s Customer Support team partnered with Idiomatic to strategically scale & improve support operations using advanced, real-time ticket categorization.

Idiomatic integrated with Zendesk to analyze and categorize Instacart’s support contacts in real-time. By assigning Idiomatic’s customized AI categorizations to tickets in Zendesk, Instacart streamlined support workflows with ticket routing, agent specialization, and spike notifications.
