Case study
Rowan Carstensen and Andrea Savi were studying together when they had their lightbulb moment for a business: they identified a gap in the market for propellers, a market dominated by Chinese suppliers.

With the increased focus on supply chains and national security, the business which was started in 2023, is now well placed to flourish. It is already supplying an MOD tier one supplier. The business also sits within the advanced manufacturing sector, identified within the government’s Modern Industrial Strategy as a sector vital to the economic future of the UK.
Flyber Composites has developed a manufacturing process to enable it to develop bespoke propellers at scale and at low cost. The business focuses on propellers and fixed wing aircraft and drones for use within aerospace, aviation and defence. Alongside the manufacturing part of the business, Flyber also offers engineering and design services to its clients.
Not long after starting, the engineering and manufacturing company developed its first prototype, which was enabled by Start Up Loans financing. Andrea said “The Start Up Loans finance which Rowan and I received was vital. It’s the money that got us going by helping us build a prototype, invest in that vital research and development and from there build our credibility in the industry.”
That credibility has been recognised by investors, with two angel investors coming in, allowing the company to open a factory in Northamptonshire which will be capable of producing 30,000 propellers a year for use on hardware such as military drones.
With customers in place and their manufacturing set up, Flyber is moving onto its next exciting stage of growth, targeting raising £10m by 2027 from venture capital investors and becoming the biggest propeller supplier in Europe. This would increase national security and challenge the dominance of Chinese parts within the industry.
The business plans to expand its modular, scalable manufacturing cells, which are currently being deployed in the UK, with further plans to gain customers in North America and Europe, where they are in the process of establishing as a key tier one supplier to industry.
Flyber Composites seeks to be sustainable in how it manufactures. While carbon fibre is not a sustainable product, the business owners have made sure to recycle the waste produced during the manufacturing process into making future propellers and in that way have made their business circular and green.
Andrea Savi, co-founder of Flyber Composites, said:
We are ambitious for the future, looking to raise venture capital backing and because we are seeing increasing demand from the United States and overseas in 2027 we want to have working facilities in the US and India.
Rowan Carstensen, co-founder of Flyber Composites, added:
2026 is all about scaling for us. We’ll be focusing on consolidating our UK presence and working to build traction with US customers. In particular, we’re aiming to be a tier one supplier for the US defence sector. We’re proud to be based in the UK, as we benefit from the ‘ecosystem of expertise’ that exists here for this type of engineering work.
Louise McCoy, Managing Director, Start Up Loans Products, British Business Bank, said:
Advanced manufacturing is one of the sectors being backed in the Industrial Strategy and we’re delighted Start Up Loans can back innovative, high growth businesses with the potential to create jobs and export
