I visited Boom at the Denver suburban airport facility in 2017 as part of a MIT alumni club tour. They had a 1/3 size mockup then- no passenger seats. I wasn't sure if that was the one they were going to use for flight testing or just for show.
A point was most of the design was done done and verified by computer. The Concorde and many of the early military supersonics were designed by sliderule and wind tunnel models, just like Apollo spacecraft.
