    The Challenge

    Manual candidate screening is slow, expensive and inconsistent at scale. Role-play training takes coordination and feedback varies from trainer to trainer. And customer support queues grow faster than companies can hire and train agents.

    Our Solution

    We built langbox, one AI voice platform with three modules. langbox HIRE runs structured, brand-aligned screening interviews 24/7. langbox TRAIN offers realistic AI role-play for sales and service teams with instant, personal feedback. langbox AGENTS are branded voice agents that handle inbound and outbound calls end to end, in many languages, with a clean handoff to people when it matters.

    Results

    Objective, consistent first interviews for every candidate

    Unlimited, safe practice for sales and service teams

    Customer calls answered around the clock, in many languages

    Setup in three steps: define goals, let the AI run, get ranked results and reports
