The Human Element
Beyond Automation: In-House RevOps Experts
Our proprietary engine handles 99% of the heavy lifting, but every CRM has strict platform limitations. When HubSpot restricts automated imports for complex workflows or proprietary activity history, our in-house RevOps professionals step in.
We manually rebuild the business logic that machines can't touch, ensuring your new environment is perfectly tuned and ready for your sales team on day one.
What our experts handle manually:
Complex Workflows & Automations
Automated engines cannot migrate business logic. We manually translate and rebuild your HubSpot automations natively in HubSpot.
Restricted Activity History
Some historical data types are locked by HubSpot. Our team uses creative data-structuring to ensure no context is lost.
Custom Object Architecture
When standard mapping isn't enough, we architect and deploy custom objects in HubSpot to match your exact sales motion.

History
What happens to my historical email logs?
Every email log stored in BigContacts 'History' is migrated as a completed Engagement on the corresponding HubSpot Timeline.

Does the migration process cause downtime?
No, our direct extraction process allows your team to continue working in BigContacts until the final cutover is ready for HubSpot.
