Why teams connect Attio and Demandbase

Keep the people you sell to and the people you market to in one shared view: Attio and Demandbase sync contacts, accounts, and engagement in real time, in both directions.

Attio owns the customer relationship and the pipeline; Demandbase runs the campaigns, audiences, and outreach that fill it. The two overlap on the same people and companies — a lead in one system is a subscriber, a segment member, an event registrant, or an ad audience in the other. When that overlap is bridged by CSV exports or a nightly job, sales works from lists that no longer match reality and marketing keeps targeting people whose status has already moved on.

Stacksync syncs Deals, Workspaces, Custom objects, People in Attio with People (Persons), Activities, Campaigns, Account & Person Lists (Audiences) in Demandbase field by field, in real time, and in both directions. You decide which system owns which fields — Attio can own account and opportunity status while Demandbase owns engagement and campaign membership — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Keep Attio aligned with a billing system or ERP on customer records and plan status.
  • 02 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
  • 03 Enrich CRM Company and Contact records with Demandbase firmographics, technographics, and verified business emails through the B2B Company and Contact Details endpoints.
  • 04 Sync Opportunities and Activities two-way so CRM deal and engagement data flows into Demandbase reporting and Demandbase-calculated insights flow back to the warehouse.

Common sync patterns

Segments and audiences follow the CRM

Where Demandbase builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Attio, so who receives a campaign reflects current pipeline reality instead of a stale export.

Where Demandbase generates leads: hand-off without re-keying

New leads or responders captured in Demandbase flow into Attio assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.

New and updated people stay in step

When a contact or lead is created or edited in either system, the matching record appears or updates in the other, so campaigns reach real people and reps see who is already being marketed to.

How changes propagate between Attio and Demandbase

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.

Attio Demandbase Sub-second propagation

DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.

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

Demandbase Attio Sub-second propagation

DetectionDemandbase notifies Stacksync of record changes through webhook events. Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL.
