Devices or people that send something forcefully into the air or into action, such as rocket launchers or those who begin projects.
From Middle French 'lance' meaning to throw or hurl. The word evolved through 'launch' in English to mean starting something, with '-er' added to mean the agent doing the launching.
The same word describes both a missile launcher and a person who launches a startup—language lets us see the parallel between throwing a spear and throwing yourself into a new venture.
