About
I'm Elena — a builder at heart and founder of kukumber, a daily math practice app designed to help kids fall in love with math through 20-minute sessions of playful exercises and engaging games. Over the past 14+ years, I’ve worked at the intersection of Product, Growth, and Marketing — building tools at Microsoft, Miro, LEGO, and leading my own edtech studio, PopAppFactory, where we created 40+ learning games for children. With kukumber, I’m on a mission to make math practice something kids ask for — fun, emotionally safe, and habit-forming. We believe in soft resets, curiosity-driven learning, and digital experiences that feel like play, not pressure. And for parents? No guilt. Every minute with kukumber is screen time that counts — joyful, purposeful, and built for learning.
