Alexander Tsao, a keen rock climber for several years, was climbing the walls at a gym near his home in Redmond, Washington, when he noticed that the ropes were frequently being replaced with new ones. Just 16 at the time, Tsao wondered what happened to the old ropes. He asked the gym owners and found out the ropes had to be discarded regularly due to safety regulations. He was surprised to find that so many ropes were sent to landfills.

This discovery inspired him to find a solution to the environmental issue of climbing rope waste. He considered possible ideas and ways to up cycle the discarded ropes, deciding to turn them into leashes (拴狗带) for dogs.
