Case Study: PLNT Burger achieves 94% CSAT and automates 61% of calls with Slang.ai

How PLNT Burger Provides Better Guest Experiences with Slang.ai

Plnt Burger, a growing plant-based fast‑casual chain founded by Chef Spike Mendelsohn, needed a way to offload routine phone inquiries so in‑store staff could focus on guest experiences while keeping phone support as a channel. To solve this, Plnt Burger chose Slang.ai and its voice services—deploying a custom virtual phone agent to handle common questions and send ordering links.

Slang.ai trialed the solution at three locations with 23 custom responses and went live within two weeks; after a two‑month trial Plnt Burger rolled the virtual assistant out to all locations and plans to use Slang.ai exclusively for incoming calls. The implementation deflected routine queries like hours and parking, enabled texting of takeout/delivery links, achieved a 94% CSAT score and handled 61% of calls fully without human intervention.
