Warehouse Gravity Well

Warehouse Gravity Well is the pull a client's existing data warehouse exerts on every CDP decision. When the warehouse already holds clean identity and event data, composable tools that read from it (Hightouch, DinMo, Jitsu) activate segments in days, while full-suite platforms (Braze, Insider One) require re-ingesting that data into a second store. The framework asks one question before any demo: where does the client's authoritative customer record already live? If it lives in Snowflake or BigQuery, a composable layer wins on speed and governance; if it lives nowhere, a full-suite platform earns its premium by supplying the profile store itself. For agencies, this decides retainer scope: composable work is often a fixed build plus a smaller monthly activation fee, while full-suite work carries a larger recurring license the client will scrutinize. Misreading the gravity well means selling a second warehouse the client never needed, or under-delivering personalization because no profile store existed to begin with.
