Heritage
Multilingual text software since the Newton
Enfour began writing Asian-language text software for handheld devices with the Apple Newton in 1993. Our multilingual and CJK text technology became core technology in products from Apple, Nokia, Psion, and Sony.
Since then we have published dictionary and reference apps with Oxford, Longman, Kenkyusha, American Heritage, Collins, Cambridge, Yale, Pearson Education, Kodansha, and Nikkei BP.
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.
