  • "Exhibiting at DSEI for the first time was invaluable for Hadean, fittingly placing us within the Tech Zone as a go-to supplier for AI-powered spatial computing. This opportunity highlighted how our technology bridges the physical and virtual worlds, reaffirming our position as a leading non-traditional disruptive tech company in defence."

  • “There is simply no other single event in the calendar which so successfully connects the global military community with the cutting-edge technologies of our leading partners. For the British Army, DSEI has never been so important and I am therefore particularly grateful for the support you provided and for enabling the week of ministerial, international and industry engagements."
