Simon Berry
| co-founder and CEO | ColaLife
+44 (0)7932 107109 (mobile and whatsapp) | skype: sxberry | simon [at]

Simon is an accidental, award-winning innovator, designer and social entrepreneur. He is also an inspirational speaker on access to medicines in developing countries, design and open innovation. Simon is the visionary behind ColaLife that transformed access to the recommended diarrhoea treatment (ORS and Zinc) for children in Zambia. In 2017 he also instigated an effort to get co-packaged ORS and Zinc on the WHO Essential Medicines List (EML). This was achieved in Jul-19.

Simon is now working, through the Diarrhoea Innovations Group, to build on this global EML listing and speed up the adoption of this change by national governments. If all cases of diarrhoea received ORS and Zinc, mortality would be cut by 90% (saving more that 450,000 lives a year). This work will lead to an increased demand for ColaLife’s findings and learning from Zambia which ColaLife shares freely.

Over a 40-year career Simon has been a leader in the voluntary, private and public sectors. He has lived and worked in South America, the Caribbean, North Africa, sub-Saharan Africa and the UK. He graduated in Agriculture (BSc (Hons), Reading) and has a post graduate qualification in Tropical Animal Health (MSc, Edinburgh).

In 2015 Simon was elected to the Ashoka Fellowship of social entrepreneurs.

Jane Berry | co-founder, business development director | ColaLife
jane [at] colalife [dot] org

Jane has worked with Simon for over 20 years; they work best on innovations together. She is ColaLife’s researcher and bid-writer. She advises on business elements, works with Simon to design presentations, workshops and communications, and ghost writes the best bits of the blog (allegedly). A wordsmith by vocation, she found an outlet in researching and writing Business Plans and funding bids for non-profits and Social Enterprises, as well as managing a range of capacity building programmes for the ‘Third Sector’.

A qualified Business Counsellor and trainer, she has a track record as an inventive and creative project manager, designing whole programmes as well as events, tools and learning games to bring enterprise concepts to the non-profit sector. These have included Women’s Enterprise and ICT initiatives for EU-funded programmes; DirectSupport – organisational development for small community-based enterprises – commissioned by the UK’s Department for Education and Skills (now DIUS), and net:gain – an ICT strategic development programme for non-profits.

Jane originally trained as a linguist and spent over 12 years in developing countries teaching English; she has also been on Social Enterprise study trips to China, Japan and in Europe. Jane has been involved in successful partnership working with Local Authorities, Government Departments, non-departmental bodies, Higher Education institutions, Support Organisations, Social Enterprises and community groups. She is a consummate ‘digester of detail’ and a ‘completer-finisher’ who likes the challenge of delivering to deadline and budget.
