Momento, a company focused on providing a serverless caching service, has developed a streamlined key-value service that abstracts complex processes into three simple API calls. This approach, inspired by the operational excellence learned from building DynamoDB, has quickly matured Momento into a key player, earning partnerships with Google Cloud and clients like CBS and Wyze. Over the past six months, the team has prioritized customer feedback, discovering that users prefer an intuitive API with basic capabilities rather than a multitude of features. Responding to this, Momento has begun transforming its service by introducing collection data types (CDTs) such as dictionaries, sets, and lists, which address various workloads and enhance flexibility and scalability. As they continue to iterate and expand their offerings, Momento invites customers to share their needs and feedback on new features, fostering a collaborative development environment.
