Ask HN: Buyer Intent Chrome Extension for LinkedIn Sales Nav

I am curious to know how you gather intent about a user. Funding is on Crunchbase, company size is on ZoomInfo, and footprints are on LinkedIn. Plus, there's keywords search volume, job changes, hiring velocity.

What do you think about a Chrome extension for LinkedIn Sales Nav that displays all buyer intent from different internet resources (Crunchbase, LeadIQ, Rocketreach, Apollo, and all LinkedIn data about them, their activities, their company, and company activities such as hiring velocity and job changes) beside each person in the search results? The data would be displayed insightfully with charts, perhaps with a score for each person.

How useful will this extension be? Are there any other ways you'd suggest to find which accounts are looking to buy your product? What key indicators do you look for in them?
