About us: founders Dan Slater & Rosie Slater


In 2013 Dan Slater founded the Delphi Network with his sister Rosie, and they built it to be Tokyo’s leading bespoke business intelligence and relationship-building service based. Prior to that, he was the director of The Economist Group’s Corporate Network (ECN). During that time, he won a company prize for designing a new program aimed at Japanese staff working with foreign companies; appeared frequently on CNBC and BBC commenting on the political and economic changes; and almost doubled the number of members. Much of this growth came thanks to a unique series of events after the 3/11 tsunami and earthquake. During this time, Dan and his team stayed in Tokyo and employed his skills as a former journalist to help ECN members with decisions regarding their future in Tokyo, taking into consideration radiation and quake risks, evacuation choices, the political fall-out and the economic consequences of 3/11.

When Dan came to Japan in 2008, he had spent the 12 previous years in China, where he worked as a foreign correspondent and deputy editor for FinanceAsia, the region’s leading finance title. During that time, he focused on some of the most vital and controversial developments in the region, including the evolution of China’s economy, the rise of its private sector, and the unique social atmosphere that accompanied such a transformation. He also met many of China’s most famous and infamous entrepreneurs. Some of these are now dead or in jail, while others have capitalised on their early success and have become respectable and respected businessmen and women.

He holds a degree in Oriental Studies (Chinese) from Oxford University and an MSc in International Relations from the London School of Economics. He speaks Chinese, French and German fluently.

Rosie Slater joined forces with her brother Dan in Tokyo in 2013 to co-found The Delphi Network, where she was principally responsible for business development. In 2018, she headed to Singapore and joined IMA Asia, a peer group forum for Asia CEOs and senior executives, as its Forum Director. Since April 2023, Rosie is expanding the Delphi Network’s footprint beyond Japan.  She aims to leverage the DN’s Japan business, along with the UK’s recent entry into the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and the UK-JP Comprehensive Economic Partnership Agreement (CEPA), to help Japanese businesses enhance their activities in the UK.

Rosie began her career as a financial journalist in Hong Kong, moving into financial PR at Nomura HK in 2010, and then heading to Tokyo for 6 years. She is a 4th dan aikidoka, and a former instructor at the Yoshinkan Aikido Headquarters in Tokyo. In 2020, she left Asia and returned to the UK to implement a conservation program to enhance and protect the biodiversity of the family’s 100-acre farm in Wales. This remains one of her key projects.
