Symphony

Symphony helps enterprises train their customer-facing employees using interactive AI voice simulations of real-world scenarios. Users can create an infinite number of simulations that allow their teams to practice the job - avoiding costly mistakes with real customers. For example, we’re live with 2 of the top 3 auto insurers in NA, helping train 1000s of newly hired claims adjusters.
