Founder#

Ben Smith is a British software founder and developer based in Japan. He has spent more than 20 years building software across finance, SaaS and online services, including founding Tabscanner, a profitable B2B SaaS business used by companies around the world.

Business Box grew out of his experience running small businesses in Japan, where the software on offer was either built for another country or built for much larger companies. It starts with booking and payments in yen, with agreements, invoicing and client records to follow, all made for the way small businesses in Japan actually work, in English and Japanese.

He leads the product and its development at App Dev Plus G.K. in Tokyo.
