Nowadays, private space company really succeeded and manufactures pretty good technology and space vehicle. What do you think is the most advanced private space company ( except Space X ) at the present time?

There are huge numbers of companies making components for space applications. This ranges from mathematicians and designers developing concepts to solve problems on paper, to microchip manufacturers on the small scale through to structural engineers designing and assembling large structures at the other end of the scale. This is therefore an impossible question to answer, because no one company holds all the chips.

Spam is a great private space company. This company may be going slower than SpaceX, but their success to failure ratio is unmatched.Off cource it`s not so advanced like Space X and does not so well in the space exploration area but still, spam has great spacecrafts and consepts that worth attention.
