This entire techbro anti aging cult bubble is both a lot more entertaining and makes much more sense when you simply assume it's ran by a bunch of vampires. Like, take a look at that guy. Famous for getting blood transfusions from his son, avoids sunlight at all costs, brags about his low body temperature, just has the all-around biggest Ventrue ancilla vibes you can imagine.

ofc if you want to grift people who want to avoid death at all costs, making them think you're a vampire is a fairly sound marketing concept to make them pay for premium access to your inner circle.
