IONA is an innovative logistics provider utilising drone technology to address delivery challenges in rural and remote areas. Backed by an expert team with strong ties to renowned institutions such as Cranfield University, Carbon13 and The National Robotarium, the company is developing the first drone designed for the needs and regulations of rural deliveries.

The Sonnet Quad has a patented design and tilting rotor, making it four times more energy efficient than any alternative. This provides extended range, larger cargo capacity and lower costs. The solution increases margins from existing segments like medical deliveries and opens new ones such as day-to-day rural logistics. It reaches breakeven with only 200 residents in a community, i.e., ten times fewer than delivery vans require, and saves 500kg of CO2e emissions and £400 in purchasing power per year per person due to reduced car dependency and decarbonisation.
