Startups today aim to be data-driven, generating significant data from web and mobile applications. While data warehousing has traditionally been associated with large corporations due to perceived costs and complexity, it is becoming increasingly important for startups to maintain control over their customer data. Cloud-based data warehouses like Amazon Redshift and Google BigQuery offer lower-cost, less complex solutions for data storage and analytics, making them accessible to smaller companies. Startups should establish their data strategy once they have a clear understanding of their target market and begin scaling their products. Initially, they can use early-stage cloud tools to test hypotheses, transitioning to more robust data warehousing solutions as they gain traction. This approach ensures businesses can effectively analyze and leverage their data for growth and decision-making.
