Architecture

Chime runs a proprietary fintech platform on AWS, using S3, Airflow and Spark-based data pipelines that write to Snowflake and then propagate to MySQL and DynamoDB for operational and analytics use.[1][5] AI capabilities, including call summarization, are integrated via Amazon Bedrock into this core architecture rather than being a standalone LLM-native product.[5]
