Gilmour Space Technologies

Headquarters: Australia

Filing date: 2026-11-18

Estimated valuation: $800.0M

Executive Summary

Gilmour Space Technologies is an Australian enterprise developing hybrid rocket propulsion technology to provide affordable launch services for small satellites. The company is currently moving toward its first orbital test flight of the 'Eris' rocket, positioning itself as a key player in the sovereign space capability of the Asia-Pacific region. Its business model focuses on capturing the burgeoning global demand for small satellite constellations via an Australian-based launch site. While current revenue is minimal at $10 million from early defense and research contracts, the financial potential scales significantly with a successful launch cadence. Strengths include a unique, lower-cost hybrid engine design and strong backing from the Australian government. However, the operational risk of launch failure remains the primary hurdle to commercial viability. This IPO would be a landmark event for the Australian tech sector, offering a high-risk, high-reward entry into the global space economy.
