Why teams connect Google Cloud Spanner and Nutshell

Treat Nutshell like part of your database: its records live in Google Cloud Spanner as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in Google Cloud Spanner, where it can be queried and joined like everything else.

Stacksync mirrors Tags, Users, Leads, People from Nutshell into Rows, Interleaved tables, Secondary indexes, Change streams in Google Cloud Spanner with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Nutshell with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • 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.
  • Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.
  • Consolidate data from a globally distributed Spanner deployment into regional business systems.

Query the CRM like a database

Accounts, contacts, and custom objects from Nutshell become tables in Google Cloud Spanner you can join with application data directly.

Product events onto CRM records

Internal tools without API code
