Fund managers Andrew Buchanan and Kate Tidbury join Octopus and will continue to run the funds.
The deal brings the total number of VCTs run by Octopus to 15 with £250m in assets.
Buchanan has spent 35 years in fund management. He was at Rutherford Asset Management, a specialist in small and unquoted companies, for four years until it was bought by Close in 1997. As well as VCTs, he has worked on inheritance tax and enterprise investment scheme portfolios investing in Aim.
Tidbury joined Close in 2000, after working at Chase and Panmure Gordon. She has experience in running specialist ethical and small and mid-cap funds.
Director Chris Hulatt says: “We believe the transfer of these funds further cements our position as the leading UK smaller companies house, with more than £600m invested across our 15 VCTs, our IHT and EIS portfolio services, as well as our range of Oeics. We are looking forward to working with Andrew and Kate on generating further returns for investors in these Aim VCTs.”
