Use product usage to identify upsell opportunities, create automated workflows to e.g. create opportunities and notify your sales team, send tailored emails and collateral or kick off a manual process.
Product data allows you to understand who at your company uses the product the most, and you can build workflows and processes to nurture them into advocates, leverage them for references, case studies etc
Whether going into a meeting or preparing a proposal for expansion, understanding how your customer leverage (or do not leverage) your product will give you key insights to steer towards your objectives
