The Legal Cheek View
If there’s a single phrase that captures Simpson Thacher & Bartlett, it’s this: a quiet powerhouse. Less flashy than some of its Wall Street rivals, but no less formidable for it, Simpson Thacher has spent well over a century building a reputation as one of the world’s elite corporate law firms, the kind that operates at the very top of the market without feeling the need to shout about it.
Founded by Columbia University graduates John Woodruff Simpson, Thomas Thacher and William Milo Barnum, the outfit has called New York home since 1884, making it one of the grand old names of the ‘white shoe’ set, those storied firms synonymous with blue-chip clients, big financial institutions and the upper echelons of corporate America. It was also ahead of the curve internationally, planting its flag in London back in 1971, long before the transatlantic gold rush that would eventually see US firms pile into the City en masse.
For over four decades, the London office has played a central role in the firm’s European operations, particularly in private equity and funds work, and has become a key hub for handling complex, cross-border transactions involving some of the world’s largest investment firms. It has also produced some of the City’s top lawyers, with a headcount of over 200 at its London outpost. Now, for the first time in its history, Simpson Thacher is recruiting trainee solicitors in London. The firm has historically developed a small pool of talent via an internal pipeline by sponsoring paralegals through the SQE, but this marks its first foray into external trainee recruitment this side of the pond.
Beyond the US and London, the firm has expanded its global footprint to 15 offices spanning the US, Europe, Asia and Latin America, with around 2,000 lawyers worldwide. That footprint is still growing. In spring 2026, Simpson Thacher announced plans to open an office in Singapore, returning to the city-state after a more than 20-year absence.
Simpson Thacher is widely regarded as one of the premier firms for top-tier private equity work globally. The firm acts for an enviable roster of sponsor-side clients, including the likes of KKR, Blackstone and Apollo Global Management, three of the world’s largest asset managers. Deals regularly run into the billions, and the size of acquisitions can rival the GDP of a small country. For trainee hopefuls, this means exposure to some of the largest and most complex buyouts, exits and fundraisings in the market.
Closely intertwined with its private equity strength is its funds practice. The firm is a go-to adviser on the formation and structuring of investment funds, helping clients raise vast pools of capital for deployment across markets worldwide. Add to that a formidable capital markets offering spanning IPOs, debt issuances and other securities work, alongside a strong banking and leveraged finance practice, and you have a firm right at the heart of the financial engine driving modern corporate dealmaking.
Financially, Simpson Thacher has experienced near-unparalleled growth. Global revenue has surged by an impressive 22.5% to $3.55 billion (£2.7 billion), while profits per equity partner have risen 11.8% to $8.57 million (£6.3 million), placing it among the world’s most profitable firms. The firm’s latest partner promotions round offered further evidence of its upward trajectory, with a record 59 lawyers elevated to the partnership, up from 44 the previous year. Five of those promotions were in London.
Simpson Thacher’s London base in CityPoint is expanding in step with the firm’s rapid growth, fuelled by a steady stream of high-profile lateral hires. The US outfit is set to take on an additional floor in the 36-storey tower, bringing its footprint to an impressive ten levels. It’s not the only legal heavyweight in the building either, with Willkie Farr and Simmons & Simmons both calling CityPoint home.
From its upper floors, lawyers are treated to sweeping views across the City, from the greenery of Finsbury Circus to the unmistakable brutalism of Barbican Estate, with St Paul’s Cathedral spire punctuating the skyline in the distance.
Downstairs, the building delivers just as much: a lively mix of coffee spots, lunch options and a smart business lounge make it easy to step away from the desk, while the plaza outside (often buzzing with street food vendors serving flavours from around the globe) provides a suntrap setting for informal meetings, catch-ups, or a well-earned breather.
The firm operates with the lean staffing model typical of US practices. Trainee intakes are set to be small initially, teams are tight-knit, and the expectation is that juniors will take on meaningful responsibility from an early stage. For those who thrive in this environment, the rewards are significant. Think exposure to high-value transactions, close contact with senior lawyers, and a steep learning curve that accelerates development.
Of course, the flip side is intensity. Like many US firms in London, Simpson Thacher is known for demanding hours and a fast-paced, deal-driven culture. Transactions can be unpredictable, timelines tight, and client expectations high. But this is the trade-off that defines the US firm proposition. In return for the pressure, lawyers are compensated with some of the highest salaries in the UK market. Pay at Simpson Thacher sits firmly at the top end, with trainees and newly qualified solicitors earning well above Magic Circle rates, alongside the potential for performance-related bonuses.
For aspiring lawyers weighing up their options, the appeal is clear. If you’re drawn to high-value corporate work, interested in the mechanics of private equity, and prepared to meet the demands of a fast-paced, high-performance environment, Simpson Thacher offers a compelling training ground. You’ll find yourself at the heart of some of the biggest deals in the market, learning from lawyers who are among the best in their field.
