Our Story
On April 30, 2019, a shooter entered a classroom at UNC Charlotte. One student heroically tackled the gunman, saving others but losing his life. In nearby rooms, students tried to barricade doors with desks—yet had no way to lock them.
Moved by this tragedy, our founder Nikolas Ackerman envisioned a simple, universal solution to protect classrooms and prevent such sacrifice.
Born at Notre Dame, DoorBlockade was created to empower people in critical moments.
Engineered for speed, simplicity, and safety, it's a portable security tool trusted by experts and easy for anyone to use.
We remain rooted in the belief that every life holds sacred worth—and safety should never be a privilege. In uncertain times, we offer peace of mind that’s fast, reliable, and built to serve.
