MongoDB's sales organization was struggling with disorganized data and disparate spreadsheets, making it difficult for sales leaders to implement strategy. To address this issue, they built an internal tool called Argos using MongoDB Atlas, which provides a current view of customer data and helps employees understand potential spend for each account. The tool has improved transparency, access to timely data, speed, and clarity about equitable territories, allowing the team to be more agile in building and adjusting territories. The simplicity of Atlas made it easy for developers to build Argos, while its flexibility allowed teams to alter the application as requirements evolved.
