Jonah (Yihui) Jin

Managing Director & Project Manager

Who Am I?

In 2021, I co-founded Tengye International with the support of CEO Lu Qinsheng and the Tengye factory. I am dedicated to serving tech companies worldwide, specializing in addressing magnet-related design challenges during the early stages of product development. In essence, I help engineers find the optimal magnet solutions for their needs.

We have a U.S. company called MagnetPeak Solutions LLC. I regularly write in “Build in Public” to share behind-the-scenes stories, helping you learn more about our capabilities and build trust with both me and our team.

Why Magnets?

I didn’t choose magnets; they somehow found their way into my life. Back in 2019, I was job hunting in international sales without a strong industry preference. The first job opportunity that came my way happened to be with a magnet company. I entered a “marriage” with magnets before I truly fell in love with them.

What's My Mission?

I want to run the business in a way that’s inspiring and meaningful, utilizing my knowledge and resources in magnets and my communication skills in English. My goal is, along with my team, to provide technical solutions and design and manufacturing services in the fields of magnet materials and plastic-magnet integration.
