Who we are
Mom-of-three Cassie Ye loved spending time with her daughters, but wanted to do more than stay at home. Instead of choosing between being present for her kids and pursuing her entrepreneurial passions, Cassie started Stelle out of her Bay Area garage—hand-packaging ballet tights alongside her husband after putting their girls to bed.
Derived from the Latin word for "star," Stelle celebrates the stellar spirit in every woman and girl with quality activewear that inspires confidence and joy. Learning as we go, we are constantly improving our merchandise to provide exceptional pieces for every age and stage. As a women-led team, we design pieces that help you look and feel your best from girlhood to womanhood.
What we value
Quality
Craftsmanship matters. We create products that perform as beautifully as they look, outlasting every wash and wear.
Sincerity
Authenticity is greater than perfection. We design pieces for real life and genuine moments to meet you where you are.
Joy
Good energy is contagious. We produce apparel that lifts your mood so you feel confident, no matter how you move.
Impact
Community is everything. We support women and girls through partnerships and donations that help them pursue their passions.
How we help women & girls pursue their passions
From runways to local studios, we invest in the spaces where ideas become reality. We've celebrated young creatives at New York Fashion Week and have equipped budding fitness entrepreneurs to help women and girls pursue their paths—whether in modeling, creating, or building their own businesses.

Ways we give back
Everyone deserves access to quality gear that helps them move, grow, and explore what matters to them. That's why we've worked with organizations that serve communities that need it most. Whether it's a university dance club or a nonprofit program, we donate thousands of pieces each year to show up with real resources that make a difference.
