History

Since 1993

Enfour began with Asian-language text software for handheld devices, starting with the Apple Newton in 1993. That multilingual and CJK text technology went on to become core technology in products from Apple, Nokia, Psion, and Sony.

We then turned the same expertise to reference. Working with Oxford, Longman, Kenkyusha, American Heritage, Collins, Cambridge, Yale, Pearson Education, Kodansha, and Nikkei BP, we have published dictionary and reference apps, and today offer 57 dictionary, language, and reference apps for iPhone, iPad, and Mac.

In 2018, well before blockchain payments reached the mainstream, Enfour founded SEN: a digital currency for digital content. We designed its crypto token, a micro-payment system that lets readers pay creators directly, and Content SENtry, a copyright clearinghouse for clearing rights online. Led by our CEO Richard Northcott from Tokyo, SEN brought together the SEN Foundation and the Digital Content Foundation, and shows how we work: explore early, take on hard problems, and build across borders.

Today

Working directly for businesses

Alongside our apps, we now offer Systems Administration and Software Development directly to businesses. The approach is the one we have always taken: careful, multilingual, and long-term.
