Why teams connect Clearbit and Nutshell

Run Clearbit and Nutshell side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.

Clearbit is a read-only source: Stacksync reads its data in real time and delivers it into Nutshell, so Nutshell always reflects the current state of Clearbit — without exports, scripts, or schedulers.

Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.

Common use cases

  • Refresh firmographic fields on existing accounts on a schedule so segmentation stays current.
  • Enrich new CRM leads with person and company attributes as they are created, keyed by email and domain.
  • Write subscription or product data from internal systems into Nutshell so reps see account context.
  • Mirror tasks and activities into ops tools for cross-team visibility.

Divisional or regional split

Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.

Where both track pipeline: deal visibility across systems

Deal stage and value on shared accounts stay visible from either CRM.

Post-acquisition consolidation

Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
