Two Sigma Investments has launched three new hedge funds this year and brought in more than $1.1bn in fresh capital, as investors remain largely unfazed by ongoing internal tensions between its billionaire founders, according to a report by Bloomberg. Assets under management have reportedly risen to a record level of more than $70bn, up from about $60bn in January.

The quantitative manager introduces a multistrategy vehicle, an equity market-neutral fund, and is seeking to raise for a tax minimising strategy.

The Titan multistrategy fund raised more than $1bn as of May, while the Aurora equity market-neutral fund gathered around $70m. The Beacon tax-aware fund attracted $54m by August, with a separate Goldman Sachs feeder fund having raised a further $11m. The firm's flagship Absolute Return Enhanced fund gained about 13% through November.

Two Sigma now operates more than two dozen funds and employs roughly 1,700 staff across technology, research and portfolio management.
