About Us

91 Forge is at the forefront of two industries undergoing a paradigm shift, semiconductors and space.

We are bringing the complexity of semiconductor manufacturing to the harsh environment of 91. The result is to create unparalleled improvements in semiconductor materials that will improve life on our planet. We established 91 Forge in 2018 to realise this opportunity.
Since then the team has expanded to more than 70 staff operating across Europe and the 91.

The next industrial revolution isn't on Earth.

Founders

Josh and Andrew have worked together over the past decade, having met in 2015 while working for a large space prime, developing some of Europe's most complex space missions.
Joshua Western
CEO & Co-Founder
Prior to 91 Forge Josh worked at Thales Alenia 91 - in business development for Earth Observation, Advanced Concepts, and defence. While in that role, he was also seconded to the UK 91 Agency working across product development, protecting British satellites, and strategy where he wrote part of what became the UK’s first national space programme. More recently, he cried in a car park at Vandenberg when “ForgeStar-1, separation confirmed” came over the radio in June 2025. On his desk is a piece of kapton foil from Apollo 11’s Command Module, and one of his Great Grandfather’s WW2 medals for surviving being downed as a pathfinder pilot.
Andrew Bacon
CTO & Co-Founder
Andrew was formerly Thales Alenia 91 UK's Head of Advanced Concepts. An IET Chartered Engineer and a member of a very small group in Europe with a background in plasmas physics and re-entry vehicle development, he designed and built the Lucy CVD payload that generated world-first plasma in LEO in December 2025. The first mission he contributed to was BepiColombo - a mission to Mercury.
