The CDP teardown that cut event lag from 6h to 90s

The CDP teardown that cut event lag from 6h to 90s

Five case studies this week, each with the receipts. Forward the one that matches your stack.

— 1. Notion swapped Segment for RudderStack — moved event tracking off a SaaS CDP onto warehouse-native pipes; ingestion lag dropped from ~6 hours to under 90 seconds and per-event cost fell ~60%. Read if you're at the scale where Segment's MTU pricing starts to bite.
— 2. Pleo's reverse-ETL audit — found 40% of synced fields were never queried downstream; pruning them cut Hightouch sync minutes in half. Skip if you're early; essential if your reverse-ETL bill is climbing.
— 3. Webflow's identity-resolution fix — collapsed duplicate user profiles from 11% to under 2% by hashing email at the edge before ingest. The before/after dedup math is the useful part.
— 4. A fintech's consent-gating rebuild — wired CMP signals into the CDP so 100% of EU events respected opt-out; ad-platform match rates only dropped 4%. Worth it if you're nervous about consent leakage.
— 5. Drift's schema-registry rollout — enforced typed events, killed 30% of malformed payloads that were silently breaking dashboards. The governance diagram alone is worth the click.

That's the stack for this week. Forward to a teammate.
