On the other hand, I just saw that "Quill was founded by the former creative director of Stripe, Ludwig Pettersson". [1] And who was Stripe's CEO, but Jack. So this could easily have been Jack arranging an acquihire for a pal.
Stripe was founded by Patrick and John Collison. I’m guessing you’re confusing it with Square, another payments company, which was co-founded and still run by Jack Dorsey.
Sorry. My mistake absolutely. Thanks for the correction. Not the first time I've accidentally mixed up the two finance companies named for common one-syllable words starting with s and ending with e. I'll be more careful next time.
