Space start ups are quickly becoming a large industry. It's not just companies focused on rockets, it's also companies with focus on satellites, GIS systems, communication systems, building materials for space industry, etc.
After a little searching, I found 3 platforms that can be utilized for funding new space start ups: Karman, Kosmic Apple, and Moonshot Space Co.
