Steffi Jem Yang, Founder & CEO of by.JemNails since 2024.

Hello world! I’m Steffi, a nail enthusiast turned founder of by.JemNails, born and raised right here in Minnesota.
My journey began during the 2020 pandemic. Like many, I needed a new hobby, but more importantly, money was tight and I was on a strict budget. That spark of necessity ignited my passion for luxury press-on nails. By 2024, I decided to take a leap of faith, turning my beloved creative outlet into a dedicated small business.
I pour genuine passion into every single set I create. I know the frustration of the traditional nail industry because I’ve lived it too:
  • Buying mass-produced press-ons only to find they don't fit your unique nail beds or your style.
  • Spending your hard-earned money and two hours in a salon chair, only to leave with a design you didn't actually want.
That is exactly why I gave life to by.JemNails. My mission is to bring custom, salon-quality, premium luxury nail sets straight to you.
I am incredibly proud to say that by.JemNails is a veteran-, minority-, and woman-owned small business. Welcome to the family!

And that is exactly why I wanted to give by.JemNails life. My hope is to bring salon-quality, premium, luxury nail sets to the everyday consumer, like you and me. 

I am proud to be the owner of a veteran-, minority-, and woman-owned small business.
