Investment trust Merian Chrysalis has raised £100m for further investments.
The trust had originally asked for only £50m but stated the final amount was at the board's discretion and the placing of new shares would be closed if it exceeded £75m.
The Chrysalis trust, which was launched last year, invests in a small number of unquoted companies.
It stated in March the fund managers had a pipeline of eight companies with whom they were in discussions about investing, spanning sectors such as fintech, ecommerce and software-as-a-service.
A total of 90,909,091 ordinary shares have now been issued at a price of 110p per share, leading to a total of 190,909,091 ordinary shares in issue.
Richard Watts, co-fund manager, said: "The Chrysalis proposition is resonating strongly with late-stage, private companies that are seeking new investors as they look to evolve their shareholder base, as evidenced by our ability to quickly deploy the initial Chrysalis launch proceeds."
Nick Williamson, co-fund manager, added: "The growing opportunity for crossover investing in the UK and across Europe is compelling. Investors have recognised this and the new funds that they have provided will allow us to continue to pursue our exciting pipeline of opportunities."
Merian Chrysalis is an investment trust run by Merian Global Investors, a global investment company worth £28.9bn.
It was the first investment trust launched by Merian, formerly Old Mutual Global Investors, when it launched in November 2018.
The trust raised £100m at launch, less than the £200m it had originally targeted, and its aim was to have between seven and 15 investments in early stage unquoted companies.
