Our mission is to make Plaid’s network data easy to query, highly accurate, and legally compliant. The infrastructure we build is used by product and machine learning teams across the company to develop high-precision features, analytics, and customer experiences. We focus on enabling consistent data access across both real-time and offline workflows.
