Octopus has promoted Ruth Handcock as chief executive of its investment business as company co-founder Simon Rogerson steps back.
Rogerson will remain CEO of the wider group and executive chair of Octopus Investments, which runs tax efficient investments and planning, in addition to a peer-to-peer secured lending service.
The unit runs £6 billion in retail funds, the bulk of the wider group's £8.5 billion in wider assets under management.
Handcock joined the business in July 2018 as chief customer officer. She previously worked in the same role at fledgling bank Tandem.
Rogerson said: 'We’re thrilled Ruth has agreed to take over the reins and lead Octopus Investments through its next exciting stage of growth.
'She has already made a big contribution to the business and brings with her great skills and a shared passion to see more people benefit from financial advice.
'This goal remains unchanged: we passionately believe in the difference that great financial planning can make to people, their families and lives.
'I will continue to be involved with Octopus Investments and I am looking forward to working alongside Ruth, as we support more advisers across the UK by developing meaningful financial solutions and services for them and their clients.'
Jonathan Digges, formerly head of specialistfinance at the company, becomes the new chief investment officer (CIO).
Sam Handfield-Jones, formerly head of p2p lending, will become growth and innovation director for Octopus Investments.
Handcock added: 'I’m looking forward to the challenges and opportunities that lie ahead as the company grows and continues to innovate. Technology is a huge driving force for change within financial services and we want to lead the charge.
'Octopus remains an entrepreneurial business at its core and has a talented team of people working hard to make a real difference to both our advisers and their clients. My focus will be on ensuring we continue to invest and deliver on our commitment to advisers.'
