"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."
