Why teams connect Outreach and Pinecone

Write what Pinecone computes onto the contacts, accounts, and deals in Outreach, and feed Outreach's records back into Pinecone, in real time and in both directions.

Pinecone turns data into something a revenue team can act on: scores, classifications, summaries, and embeddings. But the customers those results describe live in Outreach, where reps and marketers actually work. Intelligence that stays inside Pinecone rarely reaches the record where a decision gets made, and Pinecone is only as sharp as the data it sees, which is also held in Outreach.

Stacksync connects Backups, Index statistics, Indexes, Vectors (records) in Pinecone to Calls, Tasks, Opportunities, Users in Outreach with bi-directional, real-time sync. Records and fields from Outreach flow into Pinecone as the material it scores, indexes, or enriches, and the values Pinecone produces flow back onto the matching contact, account, or deal in Outreach, field by field, within seconds. There is no batch export in the middle and no glue code to maintain.

Because the mapping is field-level, you choose exactly which attributes cross and in which direction, so Outreach stays the record of the customer while Pinecone stays where the computation happens.

Common use cases

  • 01 Back up a namespace by exporting its vector ids, values, and metadata to object storage or a database on a schedule using the list and fetch operations.
  • 02 Write embeddings and their metadata into a Pinecone index from a Postgres or warehouse table so a semantic-search or RAG feature always queries fresh vectors.
  • 03 Suppress prospects across systems when a contact unsubscribes or a customer churns.
  • 04 Enroll leads in sequences automatically by writing sequence-state records when a lead crosses a scoring threshold in the warehouse.

Common sync patterns

Where Pinecone indexes records for retrieval: Outreach keeps it fresh

Contacts, accounts, and notes from Outreach sync into Pinecone as they change, so embeddings or search stay aligned with the live CRM instead of a stale export.

Where Pinecone summarizes or drafts: text where reps read it

Summaries, next steps, or drafted messages generated in Pinecone write back onto the account or deal in Outreach, next to the relationship they describe.

Where Pinecone enriches people or companies: fields fill in

Enriched attributes from Pinecone populate contact and company fields in Outreach, and refreshes keep them from going stale.

What you can sync between Outreach and Pinecone

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.

Outreach objects Pinecone objects How this pairing syncs
Users Seat holders used to resolve ownership on synced records Backups Point-in-time snapshots of a serverless index; created, listed, and restored into a new index on the control plane for recovery or cloning. Read as a recovery-asset inventory. Users is specific to Outreach and Backups to Pinecone — each maps to any object or custom field on the other side.
Mailboxes Connected sending accounts referenced when attributing outbound activity Index statistics Describe_index_stats returns total and per-namespace vector counts, the index dimension, and index fullness; read to size a sync and to detect drift between Pinecone and the source of truth. Mailboxes is specific to Outreach and Index statistics to Pinecone — each maps to any object or custom field on the other side.
Prospects The people being engaged; the main record kept in sync with the CRM Indexes Serverless or pod-based containers holding vectors of a fixed dimension and distance metric (cosine, dotproduct, euclidean); managed on the control plane (api.pinecone.io) via create, list, describe, configure, and delete. describe_index returns the per-index data-plane host. Prospects is specific to Outreach and Indexes to Pinecone — each maps to any object or custom field on the other side.
Accounts Companies grouping prospects, aligned with CRM account ownership Vectors (records) The core data: an id (up to 512 chars), a dense values array, optional sparse_values, and JSON metadata (up to 40 KB filterable per record). Full CRUD on the data plane via upsert, update, fetch, query, and delete, so write is supported here. Accounts is specific to Outreach and Vectors (records) to Pinecone — each maps to any object or custom field on the other side.
Sequences Multi-step cadences; synced as reference data for enrollment automation Namespaces Partitions inside an index; every read and write targets one namespace and vectors across namespaces are isolated. Enumerated with list_namespaces and sized per namespace via describe_index_stats. Sequences is specific to Outreach and Namespaces to Pinecone — each maps to any object or custom field on the other side.
Sequence states Per-prospect enrollments; writing one adds a prospect to a cadence Collections Immutable snapshots of a pod-based index that store its data but not its definition; created, listed, and deleted on the control plane and used to recreate a pod-based index. Serverless indexes use Backups instead. Sequence states is specific to Outreach and Collections to Pinecone — each maps to any object or custom field on the other side.

How changes propagate between Outreach and Pinecone

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Outreach Pinecone Sub-second propagation

DetectionOutreach notifies Stacksync of record changes through webhook events. Webhook subscriptions on resource create, update, and destroy events, plus polling.

DeliveryEach detected change is written to Pinecone through its API, with automatic retries and rate-limit backoff.

Pinecone Outreach Interval-based propagation

DetectionStacksync polls Pinecone for changes on an incremental schedule, reading only records changed since the previous pass. No webhooks and no native change-data-capture feed.

DeliveryEach detected change is written to Outreach through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Outreach: Subject to per-user hourly rate limits.
  • Pinecone: Data-plane operations are capped per second: query, upsert, update, and delete at 100 req/s per namespace, fetch at 100 req/s per index, and list at 200 req/s per index; breaches return HTTP 429. Hard request limits also apply: an upsert is max 2 MB or 1000 records, metadata max 40 KB per record, and query top_k up to 10,000 with a 4 MB result cap.

Pinecone

Integration surface
Two HTTP APIs: a control plane at api.pinecone.io (manage indexes, collections, backups, and, via the Admin API, projects and API keys) and a per-index data plane at the host returned by describe_index (upsert, query, fetch, update, delete, list). A gRPC data-plane transport is available through the official SDKs.
Authentication
API key in the Api-Key request header, scoped to one project; every request also sends an X-Pinecone-Api-Version header (date-based, e.g. 2025-10). The organization Admin API instead uses OAuth2 client-credentials (service accounts) via login.pinecone.io/oauth/token, passing a Bearer token to api.pinecone.io/admin (Enterprise).
Change detection
No webhooks and no native change-data-capture feed. Vectors carry no server-side update timestamp, so Stacksync detects changes by re-reading - paginating vector ids with the list operation (serverless indexes) and fetching by id, or by re-upserting from the source of truth. describe_index_stats bounds a resync with per-namespace counts.
