Lifecycle stage should move contacts from Subscriber and Lead toward Opportunity and Customer. When 80% or more of contacts sit in the earliest stages, or in any single stage, the funnel is not being measured. Define what moves a contact into each stage, automate those moves, and check that Customer reflects real closed won deals.
Lifecycle stage is how HubSpot connects marketing and sales reporting. If almost everyone is a Lead, you cannot see how many became marketing qualified, sales qualified, or customers, or where they stalled.
A top-heavy funnel usually has a process cause: qualification criteria nobody can meet, no automation that advances stages, or sales working leads without updating the record.
Customer is often set by hand and then drifts. Contacts marked Customer with no closed won deal, or real customers left as Leads, distort attribution and receive the wrong nurture emails.
Before you change anything: In many portals, HubSpot moves lifecycle stage forward automatically but not backward. Moving a contact to an earlier stage usually needs the value cleared first, so plan bulk corrections deliberately and test them on a few records.
There is no universal number. It depends on your sales cycle and how much top-of-funnel content you produce. The signal here is concentration: when 80% or more of staged contacts are Subscribers or Leads, very few are moving forward.
