Our Mission

To make sustainable living accessible, fun, and rewarding for everyone by gamifying eco-friendly habits and creating a supportive community where small daily actions lead to meaningful environmental impact.

Our Goal

Empower 100,000 people to adopt sustainable habits and collectively save 10,000 tons of CO₂ by 2027

Our Approach

Our Community

The Problem We're Solving

Many people care care about the environment but struggle to turn that care into consistent action.

When asked why they don't act, most say sustainable habits are "too much effort" or "small actions feel useless."

We realized: What if saving the planet could be fun, rewarding, and social? That's where Bio Habit comes in.

Meet Our Founder

Julie Sasaki

Founder & CEO of Bio Habit

I created this app to help all of us live sustainably without stress, but with fun and motivation.

Fueled by my passion for the planet, surfing, and everything I've learned in entrepreneurship and business courses I had taken over the past few years, I want to show that saving the Earth can be simple, fun, and powerful.

When I'm not building Bio Habit, you'll probably find me catching waves at sunrise, sketching ideas in my notebook, or challenge myself to eat vegan for a week!

Founder Story

Green School Bali bamboo buildingStudents at Green School Bali

My passion for sustainability started when I was eight years old at Green School Bali, a wall-less school built entirely out of bamboo. The classrooms were open to nature, they had composting toilets, and every day they weighed the amount of food waste students produced to better understand our impact. Being surrounded by a community that truly lived sustainably opened my eyes to how small, everyday actions could create real change. It wasn't just something we learned about, but it was part of our daily lives.

When I returned to Green School Bali at fourteen, I began to notice the difference even more. Life there felt so connected to the environment, but when I came back home, that way of living drastically changed. I binge-used plastic, left lights on without thinking, and wasted food without a second thought. Even though I cared deeply, it was hard to keep those habits going outside that unique environment.

I started making an effort to keep eco habits in my own life, but I noticed that my friends and family were struggling with the same thing. It wasn't that they didn't care. It was just difficult to stay consistent without motivation and fun. That's when the idea for Bio Habit began to grow. I wanted to create something that made living sustainably feel engaging, fun, and motivating no matter where you are — something that could help people build meaningful habits that actually last.
