## Success On-Demand Tier
The CSE team delivers GitLab's **On-Demand Success Tier**, providing technical product expertise and best-practice guidance to all GitLab customers through webinars, hands-on labs, office hours, and on-demand engagements. CSEs work in a pooled model and are not dedicated to specific accounts.
For customers who want a dedicated, named resource, GitLab offers paid Success Tiers:
-**Essentials** — a designated [CSM](/handbook/customer-success/csm/) for adoption, success planning, and renewal strategy
-**Advanced** — a designated [CSA](/handbook/customer-success/csm/segment/csa/) for deep technical enablement and Accelerator programs
-**Signature** — a designated CSA plus an [Assigned Support Engineer (ASE)](/handbook/support/enhanced-support-offerings/offering-assigned-support-engineer/) for the highest level of white-glove support
For an overview of all tiers, see the [Success Tiers page](/handbook/customer-success/success-services/).
