Inbot, a Berlin-based company, has developed a mobile-first CRM solution for field salespeople that leverages Elasticsearch for data management and real-time analytics. The application captures customer communications automatically from various apps, providing real-time insights and facilitating collaboration directly from mobile devices, which are ideal for data collection due to their proximity to users. By utilizing Elasticsearch's powerful aggregation features, Inbot delivers actionable insights and reports on sales activities, transforming traditionally tedious data entry tasks into automated processes. The company decided to build its backend on Elasticsearch, moving away from a MySQL prototype, due to its ability to handle vast amounts of data, real-time querying capabilities, and scalability. Despite initial industry skepticism about using Elasticsearch as a database, the Inbot team found that its advantages outweighed the challenges, especially after Elasticsearch addressed some resilience issues. The CRM features include real-time ranking of contacts based on user activity and integration of tagging systems to manage sales pipelines. Since its launch in the iOS app store, Inbot has experienced rapid growth and is focused on supporting its initial customers while adding new features, with Elasticsearch proving to be a robust and evolving solution.
