DD vand LLC builds VPC-native data reliability software for teams that move data at scale. Our flagship product, DriftLock, catches schema drift before it breaks pipelines by fingerprinting upstream structure and alerting the right people the moment a column is added, dropped, or retyped. FeedGuard validates partner and vendor feeds at ingestion, and LakeCovenant enforces data contracts across S3 lakes. Everything runs in your own network, deploys in an afternoon, and is priced to buy online. No SaaS black boxes, no enterprise theater.
