About Sunny Numbers

We are creating a fresh way to learn maths and statistics.

Our team is currently developing the prototype of our first mobile game which will help higher education students to learn statistics without procrastination.


Our goal is to offer 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.

Sunny Numbers  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

I did not learn maths at school.


I only started learning (and enjoying) maths as an adult.


As a young girl born in Brazil, my opportunities were very limited. 

At school, I was told too many times that I was not good at maths, and after some time I believed it.


I grew up thinking that only a few "gifted" people were smart enough to learn maths.

Sadly, too many students still face the same problem today.


I believe maths and statistics are life skills. My personal journey taught me how debilitating maths anxiety can be. My goal is to help students to realise their potential with maths and statistics.

For the past years, I have been researching maths and statistics anxiety. I am constantly listening to students to understand how we can help them to have a positive experience with maths.

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, psychometrics 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)  and the Start-Up Lab programme at University College Cork (Autumn 2020).


I am currently taking part in the Exxcel programme for female entrepreneurs in STEM  funded by Enterprise Ireland.


I am also 1 of 10 founders selected to take part in the Launch Programme promoted by BKK, Ronan Daly Jermyn, MGFD and Republic of Work.
