interactive investor (ii) is the UK's second-largest direct-to-consumer investment platform and its leading flat-fee provider, founded in 1995 and administering £95 billion in assets for more than 500,000 customers. The platform operates on a flat-fee pricing model rather than the percentage-based charges common among competitors - a structural distinction that shapes both its product architecture and its customer base.
The platform's core offering covers pensions, ISAs, and general investment accounts, with access to over 20,000 UK and international investment options spanning shares, funds, investment trusts, and ETFs. Alongside account administration and trade execution, ii provides daily market analysis, award-winning financial journalism, and a suite of tools designed to support investment decisions across experience levels - from first-time investors to active traders.
The technology stack supports a broad digital platform combining brokerage infrastructure, content delivery, and a social trading network where customers share investment insights and strategies. Engineering and product work at ii therefore spans areas including platform reliability and custody systems, data and analytics, content and media tooling, and community features - all within a regulated UK financial services environment.
