As well as all the amateur rocketry projects I follow, I also am quite interested in all the new space startup companies that have been forming in the last few years. Browsing youtube I found the following videos from Draper TV, where Nadir Bagaveev of Bagaveev Corporation is speaking at Draper University. Nadir is the founder and chief designer and his company is aiming to build a nanosatellite launcher.
Nadir talks about his 3D printed rockets, pumps and his experience in building a company.
To show what Nadir and his company have been up to check out this video below of one of their engines being fired, completely run by turbo pumps.
And some upper stage hardware.
