Why teams connect Demandbase and Kustomer
Keep the people you sell to and the people you market to in one shared view: Kustomer and Demandbase sync contacts, accounts, and engagement in real time, in both directions.
Kustomer 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 Users, Teams, Tags, Notes in Kustomer 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 — Kustomer 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 Escalate conversation-derived signals into the CRM as tasks or opportunities
- 02 Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
- 03 Push warehouse-computed account scores, custom fields, and audiences into Demandbase via the Data Import API so ABM campaigns and sales plays target the segments the warehouse defines.
- 04 Enrich CRM Company and Contact records with Demandbase firmographics, technographics, and verified business emails through the B2B Company and Contact Details endpoints.
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 Kustomer, 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 Kustomer 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.
What you can sync between Demandbase and Kustomer
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.
| Demandbase objects | Kustomer objects | How this pairing syncs | |
|---|---|---|---|
| People (Persons) Contact/person records with verified business email, title, seniority, and quality grades; fetched and matched via the B2B Contact endpoints and exported or imported. | Tags Labels on conversations and customers sync for categorization and analytics. | People (Persons) is specific to Demandbase and Tags to Kustomer — each maps to any object or custom field on the other side. | |
| Activities Engagement and custom activity records (web, campaign, intent); exported via Data Export and pushed in through the Data Import API using custom activity types. | Notes Internal annotations carry context alongside synced conversations. | Activities is specific to Demandbase and Notes to Kustomer — each maps to any object or custom field on the other side. | |
| Campaigns Marketing campaign records and creative assets exported through the Data Export API; read-only reporting feed. | Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | Campaigns is specific to Demandbase and Customers to Kustomer — each maps to any object or custom field on the other side. | |
| Account & Person Lists (Audiences) Named account and person segments exported via Data Export; custom audiences pushed into Demandbase through the Data Import API. Read and write. | Conversations Support threads across channels sync outward for analytics and CRM context. | Account & Person Lists (Audiences) is specific to Demandbase and Conversations to Kustomer — each maps to any object or custom field on the other side. | |
| Company Details (B2B enrichment) Firmographics, technographics, competitors, and corporate family tree fetched by domain or name via the B2B Company Search and Details endpoints; read-only enrichment. | Messages Individual messages within conversations support full-thread replication. | Company Details (B2B enrichment) is specific to Demandbase and Messages to Kustomer — each maps to any object or custom field on the other side. | |
| Change Subscriptions Company firmographic, company news, family-tree (ownership), and DB person employment subscriptions delivered as webhook alerts with a signing secret; the real-time change feed. | Companies Organization records group customers and map to CRM accounts. | Change Subscriptions is specific to Demandbase and Companies to Kustomer — each maps to any object or custom field on the other side. |
How changes propagate between Demandbase and Kustomer
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.
Demandbase Kustomer 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.
DeliveryEach detected change is written to Kustomer through its API, with automatic retries and rate-limit backoff.
Kustomer Demandbase Sub-second propagation
DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.
DeliveryEach detected change is written to Demandbase through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Demandbase: Credit-based per API call; bulk jobs accept up to 10,000 records per submission, CSV uploads up to 5GB, and result URLs stay valid 24 hours; subscription alerts page up to 5,000 entities and list endpoints up to 100 per page.
- Kustomer: Subject to the platform's API rate limits.

How the Demandbase and Kustomer connectors work
Demandbase
- Integration surface
- REST APIs (Demandbase One) - a B2B API (company/contact search, details, and match with async bulk enrichment jobs), a read-only Data Export API and a write-capable Data Import API (both async bulk jobs), and a Subscription API for webhook change alerts.
- Authentication
- JWT bearer tokens minted from Demandbase One API Key Sets at the platform level; each credential set expires after 8 hours and is rotated. Legacy single-user API tokens are deprecated.
- Change detection
- Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL secured with a signing secret; bulk reads run as async export jobs (submit, poll, download). No log-based CDC.

FAQ
Demandbase and Kustomer integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Demandbase and Kustomer: authenticate both systems, choose the objects to sync (such as Demandbase's People (Persons) and Activities), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Kustomer: Kustomer's data model centers on a customer timeline: conversations, messages, and custom object records all appear chronologically against one customer record rather than as separate tickets. Demandbase: Auth uses JWT bearer tokens from platform-level API Key Sets; each credential set expires after 8 hours, and legacy single-user tokens are deprecated. Stacksync's field mapping accounts for these differences between Demandbase and Kustomer without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Demandbase and Kustomer records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Demandbase and Kustomer connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Demandbase–Kustomer integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Demandbase and Kustomer. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
