Did any of these companies reach out to them and say "you know, we wouldn't have been able to scale beyond our previous limits without you, thank you so much guys you saved us". If not, this is so insincere that it is cringe.
Are they implying these other companies lacked knowledge and expertise to put their databases on machines with NVMe storage? Or is it that they chose to use their product? If it is the latter, they should just say these companies chose us, instead of emphasizing how they just couldn't scale past their previous limits without PlanetScale's help.
