The team acquired from Pantor (who number around 30) have been integral to the complete rebuild of Goldman's algo execution platform, which has been overseen by Chicago-based Michael Blum, who joined Goldman as a partner from KCG Holdings last year. The addition of several hundred Goldman Sachs staff in Continental Europe should raise eyebrows in the UK. Average pay per head at Goldman Sachs International in London is around £400k, suggesting the British government makes around £830m in income tax receipts alone from Goldman's 4,700 front office staff each year (plus employer's national insurance, plus the tax paid by another 1,200 employees in the back office). Last week, Goldman CEO David Solomon said that a hard Brexit will have, "an impact on where we invest in where we put people." For the moment, however, Goldman's new European staff are understood to be additive rather than substitutes for staff in London.
