About Gorilla

Gorilla was launched in September 2016 and is created by Cauldron Science.

Cauldron are specialists in creating bespoke software for behavioural scientists. Their ultimate ambition is to support the transfer of researchers' findings into front-line evidence-tested interventions.

Since 2011 we have worked on a wide range of products for specific research projects including:

  • A supermarket that nudges healthy purchasing choices designed to inform policy decisions on (among other things) food labelling
  • A fun to play and adaptive computer game to teach deaf children how to lipread
  • A constructionist and adaptive computer game to teach children (with and without dyscalculia) the basics of addition and subtraction
  • An online portal providing specialist diagnositic tests DCAL Portal to speech and language therapists to use with their clients

Gorilla is our first customer facing product. It leverages five years of experience building bespoke software for behavioural scientists and provides a user friendly environment in which to create and deploy novel tasks and experiments.

The Team

Cauldron is led by Jo Evershed (CEO) and Nick Hodges (CTO).

Jo Evershed loves brains. She is fascinated by the psychology of education, learning and joy, and wants to build her unique vision of how we can enrich ourselves through deep and meaningful interactions that delight us. She holds a BSc in Economics and Business from Oxford Brookes and has more recently (2012) finished her second degree, a BSc in Psychology at UCL, after a ten year career in the city working for the likes of Shell and Telereal Trillium.

Jo is in charge of the financial and scientific aspects of Cauldron. Her background in the City combined with her scientific research allows us to apply recent advances in psychology to real-world settings, and equally ensure that our projects stay feasible and funded while remaining scientifically valid.

Nick Hodges loves making things. He is fascinated by the psychology of play, and like Jo wants to create new and wonderful ways of bringing rich interactivity to otherwise passive activities. He has spent five years in the mobile games industry on some of its biggest and most prestigious franchises, such as Call of Duty, Lara Croft, Biohazard and Metal Gear Solid. He holds a BSc in Computer Science from the University of Bristol, and after graduating spent two years teaching English in Japan.

Nick is in charge of the technical and educational aspects of Cauldron. His background in mobile and tablet games gives us a thorough grounding in developing rich, interactive experiences, and means we have a unique approach to experiential learning. One of the key aspects of Nick's technical experience is in developing games for simultaneous release across multiple platforms. This cross-platform approach ensures that we rise above device and operating system differences, and reach as wide a market as possible.

Gorilla wouldn't be the product you see today without the help and support of our clients, collaborators, friends, colleagues and employees.
