My point is that the number will entirely vary for each user, depending on how many poor DB-related infra decisions they've made. Some users may save 99%, others may save almost nothing, right? So why say 40% here? Where did this number come from?

Personally, I will instantly distrust a new product claiming an exact number of 40% savings -- not even "up to 40%" or "over 40%", which would still be misleading, but less weird than claiming exactly 40%. Especially in the second line of the homepage, without any supporting link or information.

These aren't DB-specific tools though? Why would this count towards the savings?

If your savings math is based on very early-stage startups who made horrendously bad indexing mistakes, honestly that would reduce my trust even further. That said, I'm definitely not the audience for your product.
