If one of our posts showed up in your social media feed recently, you may have found yourself staring at a giant maple leaf with feet and thinking, “Wait… who (or what) is that?” you’re not alone. 

Yes, that big, cheerful leaf you’ve been seeing is very real. 
And yes, they have a name. 

Meet Mathy. 

So… who is Mathy? 

We officially introduced Mathy to the world a couple of weeks ago at JMM 2026 in Washington, DC, but their story actually started much earlier. 

Mathy was originally created by one of our developers, Marek Krzeminski, a few years ago as a fun internal character. Over time, they quietly became our in-office, local mathscot, popping up as mini 3D-printed Mathys around the office and even as a custom emoji someone created. 

Then, sometime last year, someone had what can only be described as a bold idea: 

What if we brought Mathy to life? 

And just like that, the giant maple leaf went from concept to costume. 

Why a mascot? 

Mathy is fun, curious, and a little playful. That’s very intentional. That’s what math should feel like. 

We believe math matters. We also believe math should be approachable, joyful, and a place where curiosity is rewarded. Mathy reminds us, and hopefully others, that math doesn’t have to be intimidating. It can be fun, and it can inspire awe. 

Taking Mathy on the road 

I’ll be honest. When we decided to bring Mathy to JMM, I was a little nervous. Conferences are busy, serious places. Would people really want to interact with a seven-foot-tall maple leaf? 

As it turns out, yes. Very much yes. 

Researchers (from postdocs to seasoned academics), educators, and undergraduate and graduate students all stopped, smiled, laughed, and asked for photos. At one point, people were actually lining up to take pictures with Mathy.

Let’s just say: Mathy was a hit. 

A few questions we get a lot 

How tall is Mathy? 
About 7 feet. They are hard to miss. 

What does Mathy love (besides math)? 
Dancing. Very much dancing. 
You can see for yourself here: Mathy's got moves!

Does Mathy talk? 
You bet they do. 

You’ll be seeing more of them

Now that Mathy has officially been introduced to the world, you’ll be seeing them more often on social media, at events, and in a few other fun places we’re cooking up. 

So if you spot a giant maple leaf dancing, waving, or talking math, now you know who they are. 

If you spot Mathy, don’t be shy, say hi.
