Digital Signal Intelligence, signal gravity, and the incrementality ledger
Digital Signal Intelligence will not become a procurement category. Signal gravity pulls every horizontal sensing layer down into the suites that already own the data, the way it pulled the CDP into the warehouse between 2020 and 2026. The defensible wedge underneath it is the incrementality ledger: a first-party record of which signals and actions caused pipeline, proven by holdout rather than inferred by attribution.
