The firm said the tax-efficient trusts were in high demand from advisers and investors, and has opened the two new trusts up for a joint fundraising effort with the aim of raising the £30m sum.
VCT fundraising hit its highest level since 2005 in April of this year, with £542m ploughed into the sector over the 2016/17 tax year.
Stuart Lewis, head of tax efficient investments at the firm, said: “This latest fundraise is in response to increased demand from financial advisers and investors for VCTs.
“By providing access to the growth potential of smaller companies in a highly tax efficient manner, AIM VCTs offer a uniquely differentiated investment proposition and are increasingly being used as a way to complement existing retirement plans.”
Both Octopus VCTs will be open until 4 April 2018 for the 2017/18 tax year and until 15 June 2018 for the following tax year, the firm announced on Wednesday.
They will target a dividend yield of 5% a year and are made up of portfolios of around 75 companies.
Richard Power, head of smaller companies at Octopus, said they would adhere to strict investment criteria and added: “We expect there to be a good pipeline of investment opportunities for our AIM VCTs coming from both newly floating and already listed AIM companies.”
Investors will have the option to split their investment 60/40 between the two VCTs or place 100% into just one.
The minimum investment is £5,000.
