G-Research is a London quantitative research and technology firm. It uses machine learning and statistics to find patterns in noisy data and predict movements in global financial markets, with researchers and engineers working from its London offices.
It publishes no pay in its ads, so its UK accounts are the main public source. They need careful reading: the firm splits its staff across two partnerships, one for the non-administrative staff and one for the administrative staff, and their first accounts cover only eight months.
What does G-Research pay?
G-Research paid its non-administrative London staff £2.17 million each on average over the eight months to 31 March 2025. That is the figure in the accounts of Braunford LLP, which employed 49 people on average and spent £106.3 million on wages and salaries.
G-Research’s UK staff sit in two partnerships that started trading on 1 August 2024. Braunford employs the non-administrative staff. Alastair LLP employs the administrative staff: 257 people on average, at about £164,000 each over the same eight months.
G-Research UK partnerships, filed accounts, 1 August 2024 to 31 March 2025
| Entity | Average staff | Wages and salaries | Per employee, 8 months |
|---|---|---|---|
| Braunford LLP (non-administrative) | 49 | £106.3 million | £2.17 million |
| Alastair LLP (administrative) | 257 | £42.0 million | £164,000 |
Each partnership had two members on average in the period. Profit paid to members is not in these figures, which cover employees only.
Is £2.17 million a G-Research salary?
No. £2.17 million is an average across the 49 non-administrative staff in Braunford LLP, at every role and level, over eight months. In a group that small a few senior earners move the average a long way, and it says nothing about what a new hire is offered.
What the figure does show is how G-Research compares. Even over eight months, it is above the full-year 2025 averages that Hudson River Trading’s UK company (£1.47 million) and Jane Street’s UK partnership ($1.88 million) filed.
What does a G-Research quant researcher earn?
Across every London firm, our estimate for a quant researcher with 1 to 3 years of experience is £195,000 to £440,000 a year before tax, base and bonus together. That estimate covers the whole London market; for G-Research itself, what its researchers report is the nearest guide.
Recruiters put the base for a mid-level quant in London at £90,000 to £130,000, and up to £200,000 at the best-paying firms.
Reported by employees, 2025Reported
Quantitative researchers at G-Research in London report an average base of about £150,000 and average additional pay of about £190,000, across all levels, as of July 2025. That base is above the mid-level band recruiters give for London.
Why do other sites quote a lower G-Research average?
Because they read the wrong partnership. Some reports quote Alastair LLP’s average of about £164,000 as G-Research’s pay, but the accounts show that Alastair employs the administrative staff. The non-administrative staff are in Braunford LLP.
How do you get a G-Research offer?
G-Research hires for depth in mathematics and statistics. Its online quiz covers probability, statistics including least-squares regression, linear algebra, calculus, programming and finance, and the interviews that follow spend a full hour on one subject at a time, mathematics among them. Shallow knowledge across many topics shows quickly.
The G-Research interview guide walks through each stage and the firm’s own reading list. The practice page has problems and questions matched to the firm, so you can find your weakest subject before an interviewer does.
