Capsule Corporation is a highly advanced technology corporation, owned by Bulma's father, Dr. Briefs. In Dragon Ball, their arch nemesis was the Red Ribbon Army. All c made and designed for them was done by none other than Dr. Gero. After Goku defeated the Red Ribbon Army, it was thought that everyone was dead, but Goku didn't finish off Gero. He let him live, which would end up almost being the fate of all the Z Warriors when Gero created the Androids.
Capsule Corp is famous for making inventions like the Dragonball Radar and gravity simulators and other extremely handy items, which are concealed in a tiny capsule. eg. hover cars, small houses, food, etc. Their wonderous adventures have easily made them one of the most recognized and richest families in the world.
Bulma is just as smart as her father, if not more so. She is always ready and willing to lend a hand to the Z-Fighters any time with fancy technology.
The main reason behind Capsule Corp.'s success is because they are able to conceal all their inventions inside tiny Capsules no larger than a person's thumb which makes them easy to carry and thus gave the company the name, "Capsule" Corp which are called for some reason in the show dyno caps.
