Otta's take on PolyAI

Theo Margolius headshot

Theo Margolius

COO of Otta

AI-driven customer service has spread quickly in recent years but has often produced limited automated voice and chatbot services.

PolyAI builds and deploys voice assistants for automating customer services, which sound like real humans. This helps companies get an infinite and cheaper supply of their best human voice operators, which reduces customer waiting times, and increases customer satisfaction and retention.

Its competitors include Microsoft's Nuance, Isoft, Interactions, SmartAction and Replicant, but PolyAI is staying ahead of others as its voice assistant can go live more quickly, in more languages, and it charges on a per-minute basis. Recent PolyAI clients include Landryโ€™s Entertainment, Greene King, Starling Bank and Viasat.

The company has the potential to completely disrupt the customer support market and its product is already working across different languages and sectors. It is available in the US and the UK, and has made significant strides in its expansion efforts in both regions.
