Very happy to have the sales engineer guy on the map for Presales & Sales Engineering tools and resources! Best place to check it out is here: https://salesengineeringmap.com/
I'm located on the Pearl Market of Social Media for your viewing pleasure! I'd suggest viewing the full and current version on its home page to see the current market for presales tools, and also to make sure the tools you use are represented in the Presales Tools Survey
