Firestorm
Drones that can be built where they are needed.
AJ2 is an angel investor in Firestorm. AJ2 is the investment vehicle of brothers Julien Lepleux and Adrien Lepleux.
What Firestorm is building
Firestorm develops unmanned aircraft and portable manufacturing systems. Its Tempest aircraft and distributed production approach connect two problems: producing capable drones and making the manufacturing capacity available closer to where those drones are needed.
The company sits at the intersection of aerospace, defense technology and manufacturing. Its work extends beyond the aircraft to the system used to produce it.
