Artly, a Seattle-based startup, is revolutionizing the coffee industry by developing robotic baristas capable of delivering high-quality coffee with the precision and consistency of industrial automation. These fully autonomous machines, trained by renowned barista Joe Yang, can create a wide range of custom drinks, including specialty espresso beverages and latte art, while addressing the challenge of scalability that independent coffee shops face. Key to their operation is a sophisticated data infrastructure that processes telemetry and sales data in real time, allowing Artly to maintain consistent quality across multiple locations. Initially using Elasticsearch, the company transitioned to ClickHouse for its superior flexibility, speed, and cost-effectiveness. ClickHouse's capabilities enable Artly to efficiently analyze data, track customer preferences, and optimize operations, supporting their expansion efforts and enhancing customer personalization without sacrificing the artisanal quality of their coffee.
