Being a product manager in an enterprise context is different. Your dashboard gets 40% adoption and you're frustrated. Then you notice finance expensing Tableau licenses and operations paying for Airtable - they're showing you exactly what problems you haven't solved yet.

Shadow IT isn't competition - it's free user research with purchase intent already proven. Finance needs specific visualizations you don't offer, operations needs workflow automation you haven't built. These are roadmap priorities users already validated with their own budgets.

The best enterprise PMs I know review SaaS expenses quarterly to discover unmet needs. When stakeholders spend their own money to solve problems, they're telling you what features matter most - listen to the signal instead of fighting the workaround.
