About Us

We're a Vancouver-based startup run by women who believe that every girl deserves the chance to unleash her full potential. We know that the foundation for a love of STEM is laid in early childhood, which is why we're dedicated to creating toys, activities, and experiences that promote curiosity, problem-solving, and exposure to STEM skills.



To empower girls with the tools they need to thrive in STEM, we're revolutionizing the world of "girl toys." Our innovative and sassy products promote curiosity, inquiry, and analysis, and make STEM fun, relevant, and accessible.
We see a future where girls everywhere have equal opportunities to pursue careers in STEM. Our goal is to raise the bar of what's considered a "girl toy" and close the gender gap in STEM careers for good.                                                                                                                                             

Sass: We believe that STEM and style can coexist, and that's why we infuse our products with a healthy dose of sass.

Curiosity, Inquiry, and Analysis: Our toys are designed to promote problem-solving skills and encourage girls to ask questions and think critically.

Storytelling: We know that stories stick with us, which is why we incorporate role-play and storytelling into our play-sets and experiments. We want to make learning an adventure!

Join us on our journey to create a brighter future for girls in STEM. Shop our products now and watch your little one's potential soar!"
