About Sunny Numbers

Sunny Numbers is an edtech startup specialising in gamified statistics. We create mobile games to help you to learn statistics in a convenient, playful and engaging way.

We are currently developing the prototype of our first product which is a mobile game to help higher education students to learn statistics, anywhere, anytime.  

Our mobile game offers a convenient, playful and engaging learning experience that reduces statistics anxiety. 

There is a substantial body of research suggesting that statistics anxiety can compromise undergraduate students’ performance in statistics courses. Research suggests that up to 80% of students report some level of statistics anxiety during their academic journey.

Our business is committed to donate part of its profits towards organisations that provide maths education to underprivileged students in Ireland.


Our long-term vision is to expand globally and continue to invest in technology to create  innovative products within the maths edtech industry.

About Cleidi Hearn

My mission is to make statistical skills easy, fun, and accessible to everyone. I am passionate about helping students to overcome statistics anxiety.

I have a background in teaching and research, and I have recently completed a degree in applied psychology  (First Class Honours, Class 2020)  at University College Cork, Ireland. My final year thesis was a quantitative research study on statistics anxiety. My research interests are maths/statistics anxiety and  behavioural data analysis. I am fluent in English, Portuguese and French. In addition, I am member of the Psychological Society of Ireland.

I completed the Student Inc. programme (Summer 2020) . In addition,  I have completed the Start-Up Lab programme at University College Cork (Autumn 2020). I am currently taking part in the Exxcel programme for female entrepreneurs in the Rubicon Centre.
