Learn calculus.
Make a friend.
345pi turns calculus into a social experience — collaborative problem-solving that makes the hardest math click, together. We're transforming math education.
Calculus loses students before they ever fall in love with it
Two things get in the way: dense material that's hard to learn alone, and the isolation that drains motivation. We hear it from students constantly.
“The textbook is hard to understand.”
“Studying on Zoom, I feel lonely and isolated. I miss working through problems with my friends.”
Collaborative calculus
By making calculus collaborative, we improve both the effectiveness and the appeal of how it's taught — and that improved experience leads more students toward STEM.
Calculus is better together
Students learn alongside peers, working through problems collaboratively instead of grinding through a textbook alone.
Grounded in research
Our pedagogy is shaped by ongoing user discovery and research partnerships, not guesswork.
Delight drives interest
When learning feels good, students stick with it — fueling deeper interest in calculus and STEM careers.
Building the future of math education
Our team is focused on deep user discovery — refining the product, our value proposition, and our model through real research and development, in partnership with leading institutions.
