The fundraise, which saw a highly-regarded family office and “strategic individuals” in the finance industry pour in some more cash, valued Vo1t at US$17mln post-money.
Following the latest round of financing and the conversion of loan notes, KR1’s 7.94% stake in Vo1t is now worth US$1.4mln.
NEX-listed KR1 paid US$260,000 (£200,000) for a 5% stake in Vo1t just over a year ago.
“Since its inception we have seen Vo1t gain great traction, continuing to onboard new clients and consistently generating revenue every month,” said KR1 chief executive George McDonaugh.
“This year and with the funds raised, they have extended their service offering significantly to exchanges and leading financial institutions exploring digital assets and the blockchain space.
He added: “The company’s assets in custody increased significantly from our seed round participation earlier in 2017.”
KR1 shares were changing hand for 6.25p in early afternoon trade on Monday.
