Amazon Lex-Powered bot helped one business upsell worth 90 million USD

Srijan worked with a global cleaning solution to help onboard assets to the IoT ecosystem, and collect, monitor, and analyze sensor data in real-time with the help of data visualization dashboards. This helped them track equipment conditions across their customer sites and automatically offer to serve as and when required. 

Srijan then suggested building a chatbot in addition to the dashboards to find relevant data. Chatbots worked on “ask-and-answer” approach and on simply asking a query, the bot, available via mobile apps would analyze necessary data to give an answer.

Amazon Lex was used as the base interface for building the chatbots. Deep learning functionalities and natural language understanding in Lex allowed creating conversations that accurately captured the business logic. The bot built was equipped in delivering information on equipment performance metrics, the equipment health, savings potential and could help with which equipment to use in which scenario.

Building bots using Lex helped the client in the upselling business worth 90 million USD and increased the user retention of the beta user group from 8% to 42%, boosting the product upselling. It also allowed the analytics team to automate a lot of tasks which earlier happened over spreadsheets.
