Hedge fund Two Sigma's spacious new office in London makes it Jane Street's neighbour. 3 hours ago Quant hedge fund Two Sigma has had its share of controversy in recent years, particularly regarding the squabbles between co-founders John Overdeck and David Siegel. Despite this, the fund posted its best returns of the decade so far in 2025. As it looks to improve further, the fund has found itself a new office in London. Companies House filings show Two Sigma has changed offices to the fifth floor of 7 Devonshire Square, located near Liverpool Street. Devonshire Square's website shows that the fund occupies the floor by itself. It's understood that it will also occupy the sixth floor after undergoing refurbishments. Two Sigma should recognize one of it's new neighbours, Jane Street, which has an office on the same estate, occupying the entirety of 212 Devonshire Square. This might be a fleeting arrangement, as Jane Street is reportedly looking to expand its office footprint in London and is exploring moves elsewhere. Two Sigma used to live in City Tower on Basinghall Street occupying three floors. However, the new office is thought to have a larger square footage of around 20,000 square feet (including the second floor once completed). The office will be able to house roughly 200 people; Companies House accounts for its UK entities showed it had 107 UK employees in 2024 (predominantly engineers), and its website states it still has over 100 people in London.

Hedge fund Two Sigma hired a top Goldman Sachs AI technologist in London. Goldman Sachs is one of the banks (cautiously) leading the charge on AI, so much so that it's already using the technology as a justification to cut staff. Some hedge funds have been on the hype train even earlier, however, and one that has been using generative AI as early as 2019 just poached one of Goldman's top AI technologists. Francesco Maria Delle Fave has joined Two Sigma in London as a senior vice president for AI and machine learning, working on tools that power the quant fund's research platform. He's a PhD mathematician that spent the last eight years working at Goldman across a number of roles, including EMEA head of applied AI and EMEA head of its data science and machine learning in quantitative finance (DSML QF) team. He first joined the firm as a quant strat. Delle Fave has previously professed an interest in reinforcement learning (RL), a comparatively niche AI technique compared to machine learning (ML) and natural language processing (NLP). He's also a big fan of synthetic data. Two Sigma, too, has been working on RL since at least 2021. The fund is also a veteran in the natural language processing space; AI core team lead Mike Schuster said at a Columbia University conference in 2024 that Two Sigma had used generative AI for at least five years and NLP for more than a decade. Two Sigma's London office pays staff well; 'wages and salaries' in its UK entity were £377k ($507k) per head in its most recent annual accounts via Companies House, above the likes of Citadel and Brevan Howard. In the US, Two Sigma employs AI researchers on $220k in salary alone. Have a confidential story, tip, or comment you'd like to share? Contact: Telegram: @AlexMcMurray, WhatsApp: (+1 269 237 3950).
