Yes. Non-adoption is the single most common failure mode for CRM implementations. Industry data puts the partial or full failure rate at 70%, and the primary cause is not technical problems but employee resistance to changing established workflows. Teams revert to spreadsheets, email threads, and old habits when HubSpot does not feel faster or more useful than what they were doing before.
The root cause is usually a mismatch between what got built and how the team actually works. Companies that invest heavily in configuration, migration, and integrations while "quietly ignoring the human side of the rollout" see the highest non-adoption rates. Warning signs include declining activity logs, teams maintaining parallel spreadsheets, duplicate records accumulating, and leadership questioning report accuracy. Mitigation requires structuring the project around adoption from the start: role-specific training over 90 days, visible quick wins in the first 30 days, internal champions, and ongoing support after launch. Lean Labs addresses this directly with an adoption guarantee that includes one-on-one training and 90-day post-launch support. The goal is making HubSpot the easiest path for each team member, not just another system they are told to use.
