GeistM, a hyper growth marketing technology business, uses MongoDB Atlas to manage its large volumes of data and scale its applications. GeistM's proprietary platform Blackfire is built on top of MongoDB, providing a full turnkey solution for digital marketing. The company leverages MongoDB's flexibility, scalability, and performance capabilities to deliver best-in-class marketing data to its clients. With MongoDB, GeistM can easily manage large amounts of data, eliminate object-relational impedance mismatches, and alter the data model without going through a separate database delivery lifecycle. The company uses MongoDB Atlas, which provides a three-node replica set, and leverages other AWS resources such as Lambda, SQS, and S3 to support its applications. GeistM has found that using multiple data formats and casting data in different ways can improve availability and performance. Overall, MongoDB meets most of GeistM's needs and facilitates running the business. The company plans to use MongoDB for other applications, including its sister companies, and advises others to consider Atlas when hosting their own MongoDB instance.
