Neptune has appointed an adviser to work with its fund managers on Blockchain and cryptocurrencies.
The company confirmed that Jill Carlson has been appointed and will take the role of special adviser.
Neptune said Ms Carlson has advised organisations such as the World Bank and the International Monetary Fund (IMF) on the issue.
James Dowey, CIO and chief economist at Neptune said: "We are delighted to be working with Jill to understand the long term impact of this important technology on the economy."
The appointment comes at the same time as Ali Unwin has left the firm. Mr Unwin was joint manager of the Neptune Technology fund with Neptune founder Robin Geffen, who will now assume responsibility for that fund.
Mr Unwin had only been in the role of head of US equities since July 2017 and will be replaced by George Boyd Bowman.
He had replaced Robin Millway, who had himself been at the firm for less than a year.
The Neptune Technology fund has assets of £42m, and is the best performer in the IA Technology and Telecoms sector over the past year, returning 37 per cent, compared with 24 per cent for the average fund in the sector in the same time period.
Mr Geffen said: "I am excited about this opportunity for George, who has proven himself to be a great talent at Neptune over the past eight years.
"I believe he will provide great long term performance over the next decade and beyond in the US for Neptune’s investors, just as Rob Burnett has done in Europe, Chris Taylor in Japan, Mark Martin in the UK and Ewan Thompson in Emerging Markets over the past decade and more. We wish Ali all the best for the future."
