Scraping marketing leads - What would you do?

My startup RoboticLi is currently going through the MVP phase, getting the first users, receiving valuable feedback, incrementally improving the product, and putting features on the roadmap.

And I feel that now is the time to start thinking about growth.
My product is a challenger for big-name brands in the RPA/Automation branch, and for some reason, they all use a specific forum for their own communities.

(RPA startup + public forums = unlimited leads)

I have scraped their forum and collected 280.000 full names (some duplicates of course) and some (80k) personal contact details.

What would you do if there were lead sources like this for your startup?
