About Zeller

Zeller provides integrated financial services to Australian small and medium-sized businesses, combining payment processing (EFTPOS and online), invoicing, accounts management, and card issuance. Founded in 2020 and based in Melbourne, the company serves businesses that would otherwise assemble these capabilities from multiple vendors. The platform is built on a modern distributed stack—Node.js, TypeScript, React, Go—with AWS infrastructure (Lambda, DynamoDB, EventBridge, SQS, ECS) and event-driven architecture (Kafka, BPMN). The business operates across Australia and the UK.
