Jetpack company Gravity is commercializing its futuristic technology through practical, high-value niches. Instead of focusing on consumers, its go-to-market strategy targets defense applications, like boarding ships, and media opportunities. It also runs a training school to create a skilled pilot base for these operations.

Boom Supersonic's founder explains that the Concorde was a commercial failure. However, a mere 30% improvement in fuel economy—achievable with modern materials and aerodynamics—is the key threshold that makes supersonic travel profitable at business-class prices.

The wider, shorter airframe allows for six aisles, cutting boarding time to 10-15 minutes. It also provides enough overhead space for every passenger's carry-on. This improves the passenger experience and solves operational headaches, making the design compelling beyond just fuel savings.

Forterra avoids the trap of serving two masters by maintaining a defense-first roadmap. Commercial applications are pursued only when they directly benefit the core defense product by providing scale, lowering costs, and generating broader data sets for development, making the warfighter's product better.

The key driver for military adoption of micro-reactors isn't cost savings, but eliminating the vulnerability of fuel supply chains. Fuel logistics accounted for 50% of casualties in Afghanistan. This frames the product's value around mission assurance and risk reduction, a more compelling proposition than simple energy provision.

GE serves two distinct customers: powerful airframers for the initial sale and a fragmented base of hundreds of airlines for aftermarket services. This split forces new entrants to solve a '3D puzzle' of satisfying both technically demanding OEMs and a global user base simultaneously, creating an immense and durable barrier to entry.

SpaceX previously pitched using rockets for ultra-fast intercontinental travel (e.g., NYC to Tokyo in 30 minutes). While not a current focus, this concept reveals a core strategy: framing its technology as a replacement for massive existing markets, like the entire commercial airline industry. This justifies enormous valuations and ambitious long-term goals.

The most likely exit for a defense startup isn't necessarily being acquired by a large contractor. By developing a capability that can be adopted across multiple service branches (e.g., Navy, Army, Marine Corps), a startup can significantly expand its market. This "joint solution" approach creates more runway and strategic options.

Archer's strategy involves designing aircraft for both commercial and military applications from the start. This dual-use approach creates opportunities to shift manufacturing capacity based on demand, helping to re-industrialize both the civil and defense aviation sectors and providing strategic flexibility.
