Brings together the top 20 most promising space startups in Europe
The CASSINI Business Accelerator is a six-month, Europe-wide programme designed to fast-track the international expansion of high-potential space scale-ups. Supported by the European Union Agency for the Space Programme (EUSPA) and the European Commission, each programme brings together the top 20 most promising space startups in Europe.
“Being the only Irish company selected for the current CASSINI Business Accelerator is a significant milestone for us as a company,” said Aoife Kelly, founder and COO, Celtonn.
“Through the programme participants receive €75,000 cash prize, but more importantly we have had the opportunity to connect with leading European professionals, investors, and partners who are helping us accelerate our growth. We are currently seeking to finalise a €1.5m funding round to develop mission-critical capabilities, expand our engineering capacity, and accelerate deployment of our technology to international partners, so we are looking forward to pitching to potential investors at the upcoming Demo Day event.”
Through CASSINI, Celtonn has gained access to investor matchmaking, exclusive industry events, expert-led mentoring, and strategic business development guidance, all designed to strengthen its global market presence.
As part of the Enterprise Ireland’s National Space Delegation of Ireland Pavilion, Celtonn will be exhibiting at Space Tech Expo Europe alongside Ireland’s leading space companies including; MBRYONICS, Realtra Space Systems, and Emerald Aero, showcasing Ireland’s growing strength and innovation in the European space ecosystem.
