I always wondered who did their marketing. Their Arc Act II video was so good I watched it a few times (https://youtu.be/WIeJF3kL5ng?si=R1fHA87355dXDuZH).

I immediately thought Sandwich made it. Some of their stuff like https://youtu.be/5GeR8XTWR3M?si=RX-NBCMicnUPw1jA is so good I just periodically watch it.

If The Browser Company folks made that video, their superpower is really marketing and you are actually correct. But I feel like it must have been an agency.
