Boom isn't in the market for making personal airplanes as affordable and accessible as cars. What they are trying to do is to make normal air travel, as it already exists, faster. Because very large jets cost a lot of money to design and develop, they start with smaller ones and work their way up.

This first demonstrator is a two-seater. The next jet they are designing is the Overture, designed for the ~50 seater business jet segment. And as the name hints, they don't intend to stop there.
