Why teams connect Apollo.io and Materialize

Sync Apollo.io into Materialize continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Accounts, People (database records), Sequences, Deals (Opportunities) from Apollo.io land in Materialize as live tables, updated within seconds, and columns computed in Materialize write back to fields in Apollo.io. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • Drive alerting and operational tooling from SUBSCRIBE change streams instead of scheduled queries.
  • Maintain real-time inventory, usage, or account-health counters consumed by customer-facing applications.

Cleanup that sticks

Deduplication and normalization done in Materialize can be written back, so warehouse-side cleanup actually fixes the CRM.

CRM analytics on live data

Accounts, contacts, and activity from Apollo.io are queryable in Materialize moments after they change, so dashboards stop lagging the reality they describe.

Scores and segments back on the record

Lead scores, churn risk, or usage segments computed in Materialize appear as fields in Apollo.io, where the people working accounts actually see them.

What you can sync between Apollo.io and Materialize

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Apollo.io objects Materialize objects
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Tables User-managed tables that accept INSERT/UPDATE/DELETE from sync pipelines.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Sources Ingestion points (Kafka, Postgres CDC, MySQL CDC, webhook) that feed external data into Materialize.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Materialized Views Incrementally maintained query results that syncs read as continuously up-to-date datasets.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Sinks Outbound connections that emit view changes to Kafka topics.
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Indexes In-memory arrangements that make view reads fast for serving workloads.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Clusters Compute pools that isolate ingestion, view maintenance, and serving.
