To successfully launch deep technology, laboratory progress is only the first step. In order to turn technology into a risky business, a startup has to go through complex legal processes.
This week on Build Mode, Isabelle Johannessen talks to Capella Kerst, founder and CEO of geCKo Materials. Kerst was a PhD student at Stanford, working on bio-inspired adhesives – materials based on tiny hairs that allow lizards to stick to walls. He wasn’t looking to be an inventor but when he had breakthroughs that made it possible to make things faster and more reliably, he knew it was something that could be done.
But translating a lab discovery into a breakthrough is not only about the “eureka” moment but also about everything that comes after.
“I was brave enough to talk to my mentor if we needed to have a serious discussion about me taking this company out and starting it,” Capella said. And that conversation was the beginning of a long process of creating geCKo tools.
Here is a road map for those who started spinning something from education.
Five years later, GeCKo Materials continues to develop and develop new ways to use its adhesive technology that is being tested in applications from robotics and manufacturing to automobiles and even space. The company is already using it on the International Space Station, and Kerst says the long-term vision includes replacing traditional attachment methods like Velcro or suction systems.
