November’s updates reflect the continued and accelerated expansion of member contributions, increasing the depth, recency, and reliability of the co-op. As contributions scale, it reinforces our core identity stability, expands coverage, and strengthens overall model performance.
This release highlights those advancements across our product portfolio, with targeted enhancements to the B2B & B2C dataset.

We have successfully maintained a 97% UPID consistency from the last release to this one, making this one of the most stable releases to date. This continues the excellent record stability reported last month, which was 97.4%. This stability is crucial for long-term identity resolution and cohort analysis.
