First thing is first. I love the CEO, he is a mixture of my two other favorite CEOs which is Alex Karp and Elon Musk, but what stands out about him is that he is willing to say when he is wrong and he is willing to communicate with everyone on twitter. A big part of my trust comes with Peter Beck as the CEO.
Next is them not being the 2nd place to SpaceX as launches go but actually that Peter Beck isnt just trying to make a launch company, hes making a space company that has (Quote from link below) "As it turns out, total revenues at Rocket Lab surged 124% year over year to $40.7 million in Q1. And the reason for that is that Rocket Lab's new "space systems" business, which builds spacecraft for its customers, absolutely exploded in size, growing 1,873% year over year to account for 84% of company revenues at $34.2 million.
As CEO Peter Beck explained, Rocket Lab has implemented a "rapid succession of space systems acquisitions," employing its IPO cash to transform itself into an "end-to-end space company delivering complete spacecraft design and manufacturing, satellite components, flight software, and launch services." As a result, the company won a $143 million contract in Q1 to build 17 spacecraft buses for Canadian
space company MDA and its client
Globalstar.
Lastly, Peter Becks willingness to adapt and change and as their mission statement says "WE OPEN ACCESS TO SPACE TO IMPROVE LIFE ON EARTH" is a statement I can agree and support and invest in.
