As part of their expeditions, the couple invented lightweight satellite communication software and hardware solutions, which later turned into a business with customers including NASA, NGOs, defense units, and extreme explorers.

The space fleet is designed around successful principles from early Earth exploration: low cost, light travel, small and agile teams.
