At Affirm, data is fundamental to everything we do. Our data and storage solutions empower machine learning, artificial intelligence, cloud-based technologies, and other modern tools to create differential and scalable products. We prioritize building our own technology and investing in engineering talent, as we believe these are enduring competitive advantages that are difficult to replicate. Our expertise in sourcing, aggregating, protecting, and analyzing data has been what we believe to be a core competitive advantage of our platform since our founding. We use data to inform our analysis and decision-making, including risk assessment, in a way that empowers consumers and generates value for our merchants and funding sources.
