We worked with 6 YC companies who are running on Aurora postgres and worked through the inefficiencies of workloads - too many indexes (in some cases almost every column is indexed), over indexing significantly increases I/O ops (writes), this hidden costs are enormous for fully managed services like Aurora. In all these cases, we could safely come up with a plan to cut down their DB spend by more than 40%.
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.
Our goal was to tell a convincing story with case studies. However, you are right on many dimensions that this number means nothing for many optimized scenarios.
