The company
Arabesque was born in 2013, when its management bought the business out of Barclays to chase one idea: investment management run by AI. It launched its first funds in 2014, spun up a dedicated AI research division in 2019, and incubated ESG Book, a sustainability data platform now covering tens of thousands of companies, in 2018.
The flagship today is AutoCIO, an AI platform that builds, optimises and manages equity portfolios, producing daily forecasts across more than 50,000 equities. It launched in 2021 as a way for investment teams to generate customised strategies at scale, runs on Google Cloud, and in 2026 became available inside Google’s Gemini Enterprise Agent Gallery. ESG Book, meanwhile, raised a £29 million Series B in 2022 led by Energy Impact Partners with Meridiam and Allianz X.
Portfolio managers, wealth advisors and institutional investment teams, buyers who want AI-driven and sustainability-aware strategies without building the machinery themselves. The group’s named partners and users include Google Cloud, DWS, eToro and HSBC.
