Lachlan Bramble
Co-founder & CEO at Antares Aerospace
Lachlan Bramble is co-founder of Antares Aerospace, a Sydney company established in 2025 to build reusable small launch vehicles for dedicated small-satellite missions. Bramble and co-founder Ronan Kohlhoff met building rockets at UNSW, where they took a student program from a 1,000-foot model flight to a 70,000-foot vehicle. Antares plans to begin with suborbital and hypersonic flight testing to earn early revenue and gather flight data before attempting orbital launch. Its aim is to make getting a satellite into orbit as routine as overnight shipping. The company is backed by NextGen Ventures and Startmate, and it joined Startmate's Winter '26 accelerator cohort.
