Ongoing Esri capacity: 2.0 dedicated FTE for HubSpot operations, plus 0.5 to 1.0 FTE of shared capacity across Business Applications, integrations, IT, security, and marketing operations.
Super Admin access: three named internal Super Admins. Other contributors should use permission sets and scoped access.
This recommendation assumes 459 seat allocations if the two seat groups are additive. Confirm the unique active-user count before finalising headcount if the allocations overlap.
HubSpot does not publish a user-to-admin ratio. Review the allocation after the first quarter of live operations, using actual support demand, integration workload, and change volume.
Headcount should cover platform ownership, revenue operations, data, automation, integrations, reporting, training, and security governance. User administration is only one part of the work.
