I have (and still use) a 2019 mbp and it has had CPU thermal throttling issues since very early after I bought it new. Intel macs from that year were notorious for thermal throttling.
I hope this doesn't come across as toxic/negative, because I sincerely mean it to be constructive criticism. I clicked the link and left almost immediately for 2 reasons:
1. For something like this, I'd expect to see a demo video, preferably created by the tool, on the landing page.
2. Keeping #1 in mind, asking for my phone number sends up red flags, and I'm out.
