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.
