Tech plus use case
Companies running a technology and hiring for the workflow it supports.

Why it works
A tool in the stack says what a company bought, sometimes years ago. A job post for the work that tool supports says the team uses it now and has a project around it. Together they point to accounts where a related product or service has an owner and a reason to buy.
How to act on it
Prioritize accounts where the installed tech is tied to an active initiative, not just historical usage.
