As a child, Sara Spangelo dreamed of being an astronaut, attended space camp, and even made it to the final 32 candidates in the Canadian space program before being cut two years ago. But Spangelo, an aerospace engineer who has worked at NASA’s Jet Propulsion Lab and Google’s experimental arm, X, only had to shift her dreams slightly. Now the CEO of satellite startup Swarm Technologies, she has convinced two well-known entrepreneurs to lead a $25 million investment in her company: Earthlink founder Sky Dayton and PayPal co-founder David Sacks through his firm, Craft Ventures.
