Sergio Soler is Co-Founder, CFO, and Director of Automation at Arkadia Space, a pioneering green propulsion startup developing hydrogen peroxide-based systems for satellites and spacecraft.

Sergio previously worked at PLD Space, where he and the Arkadia founding team built deep expertise in space propulsion engineering and the European space supply chain.

As CFO and Director of Automation, Sergio bridges financial strategy and advanced engineering, helping position Arkadia as a leader in sustainable in-space propulsion.

Sergio co-founded Arkadia Space in 2020 alongside Francho Garcia, Francisco Espinosa, and Ismael Gutierrez, leveraging their shared PLD Space background to design practical alternatives to toxic hydrazine fuels.

Arkadia has raised over 17.3M EUR in total funding, achieved the first European hydrogen peroxide-based propulsion system in orbit in March 2025, and secured contracts with MaiaSpace and ESA.
