About
We are building Plaid for Behavioral Data—a unified API that allows users to selectively grant developers access to their digital data across various other platforms. We do the difficult work of scraping, building, and maintaining data connectors and transforming disparate data formats into a unified schema, making it immediately useful for developers. Netflix watch history, ride data from Uber, DoorDash order history, or purchase history from Amazon. Everything is cleanly structured and readily accessible. We enable powerful and novel use cases (quicker onboarding, hyper personalized insights/recommendations, consumer intelligence, etc.).
