Hi Hugo, I hope you are doing good.
At fist, Costumer Insights has been created to analyze clients (companies that have or had business with you). It gives you exceptional data to upsell or xsell business with clients, also it allows you to generate more engagement between you and your costumers.
While Market Insights Preview was discontinued, There was incorporated the core technology and learnings from Market Insights preview into Dynamics 365 Customer Insights and Microsoft Bing industry updates (more info here).
Besides that, you can use Costumer Insight to deliver personalized customer experiences and it can give some good insights of what your customer like then you can predict what are the likes and the kind of things that industry is looking for.
Other tools you can use to prospection activities are Dynamics 365 Marketing to analyze results and gain insights from you marketing activity (more info here), Bing Industry Updates for email alerts on topics of interest (more info here), Microsoft Bing Webmaster tool to do keyword research (more info here) and you can use LinkedIn Sales Navigator to target the right buyer and understand key insights (more info here).
If this answers your question, please check it as verified.
Thanks.
