ClassCalc Story

We're a diverse team with members from across the globe: UK, Brazil, Israel, Armenia, Iran and more. In some shape or form, we’ve all struggled with math - some of us overcoming our challenges in our early years, and some of us showing up at the doors of ClassCalc to give students the chance we never had. What unifies us is our deep love for math, our desire to see students & teachers succeed, and our belief that calculators should make exploring mathematics a pleasure.

CEO

I’m a drummer math-geek turned entrepreneur with a taste for food, ear for music and deep, deep love for science and education. My philosophy is that education is the highest priority, and should be made cheap and accessible for all.”

Todd Mackey

President & COO

“I’m a father to a son, passionate lifelong learning entrepreneur, all things beach lovin’, volleyball playing, world exploring lover of dark chocolate and BF The Cookie. I believe that Education is the implement of curiosity, provides access to an enriched life for us and those around us, and should be as widely accessible and easily digestible as we can make it.”

“I’m a books, cinema and game lover, who also likes to play guitar and basketball when not dabbling with artificial intelligence. In Brazil, education is painfully expensive and my goal is to drive costs as low as possible using technology.”

Dovrat Yaish

QA Lead

“I’m a dog loving, soccer playing, sweet tooth kind of a woman with a passion for food eternally afflicted with the adventure-hiking-traveling bug. I’ve trained soldiers for the Israeli military and the most important lesson I took away was the value of education.”

“I’m a chef-since-birth turned computer geek. When I’m not designing apps and algorithms, I’m either cooking weird delicacies, eating said delicacies, reading, or sleeping.”

Frontend Developer

“I love to see the results of my work bring real value to people. I enjoy delivering clean code and seeing my team productive and happy. When I’m not nose-deep in calculator code, I enjoy spending time out with my family, going camping, playing board games, going to the gym and hunting for delicious pastries.”

“I enjoy learning, programming, and taking naps. I always like to test out new algorithms and programming architecture that I can use in my apps to make them better. I also love to hang out with my friends and beat them in a game of Super Smash Bros!”
