What if you didn’t have to choose between growth and stability? Accordion’s London office offers the entrepreneurial spirit of a growing firm alongside the expertise, reputation, and infrastructure of a global leader. As part of the founding team in Europe, you’ll help shape the future of the business, work on high-impact challenges in the PE ecosystem, and be on the forefront of the firm that’s leading in AI – all while accelerating your career alongside exceptional colleagues.

It’s an experience you don’t get at other firms – and our London-based, Big 4 alumni know it best. We asked them for their Big 4 reasons for leaving Big 4:

Reason #1: You want to build something new, without starting from scratch.

Joining Accordion means getting in early and helping shape the future of a growing business, while benefiting from the experience, infrastructure, and reputation of an established global leader. There’s a unique opportunity to build something meaningful at pace, without sacrificing the support and resources needed to succeed.

Joe Niembro, Managing Director

“We have a dynamic start-up feel of the London office but supported by the proven US experience and solutions sets.”

Dani Rawson, Managing Director

“Accordion had quickly built a strong reputation in the PE market... and it felt like it was genuinely shaping the space rather than following it.”

Lucy Preston, Director

“It’s a very exciting and inspiring time to join. The team is growing, the work is growing, the list of PEs we are working with is growing...”

Carmen Harabagiu, Director

“It's a choice between being part of something disruptive and being part of something comfortable: a boutique firm moving fast and winning new ground, versus an established name with better hours but fading relevance in a rapidly shifting market.”

Reason #2: You’re looking to solve problems, not navigate red tape.

At Accordion, teams are empowered to move quickly, take ownership, and focus on creating value for clients. The result is a more hands-on, impactful way of working where outcomes matter more than process.

Dani Rawson, Managing Director

“The reduction in red tape is noticeable; decisions are made quickly, and we can engage with clients far more efficiently. There's less time spent navigating internal processes and more time working directly with clients and solving problems.”

Lucy Preston, Director

“I feel like I am doing work that makes a positive impact on our clients.”

Joe Niembro, Managing Director

“Our work is about meeting clients where they are, using AI where it helps, and rolling up our sleeves to build real capacity within their teams.”

Reason #3: You want a front row seat to value creation.

Accordion’s PE focus gives teams direct access to senior stakeholders and the opportunity to influence outcomes that matter. That means accelerated learning, greater responsibility, and a clearer connection between your work and business performance.

Dani Rawson, Managing Director

“You're much closer to decision-making and value creation, particularly in the PE space.”

Carmen Harabagiu, Director

“There’s a unique opportunity to directly influence client outcomes through the interconnected relationships between Accordion, the PE sponsor, and the portfolio company's C-suite.”

Joe Niembro, Managing Director

“Every effort is focused on an outcome aligned to the PE focus on growth, EBITDA, the multiple, and how Finance can up its game and start to lead the performance agenda.”

Nikhil Kuplish, Vice President

“You're getting real exposure to senior leadership, internally and on the client side, and that level of responsibility adds up quickly when it comes to your development.”

Reason 4: You’re looking for a team who will challenge and support you.

Accordion combines the expertise of a larger firm with the agility of a smaller one, bringing together professionals from a wide range of backgrounds and experiences. It breeds a collaborative environment where every perspective adds value, and the best teams come together quickly to solve complex problems.

Joe Niembro, Managing Director

“There are no organizational barriers that prevent putting the best team together quickly.”

Dani Rawson, Managing Director

“The diversity of experience, from former CFOs and operating partners to Big Four and boutique consultants, creates a very practical, commercially focused-approach to problem-solving.”

Nikhil Kuplish, Vice President

“The quality of the team here is excellent. Everyone had a unique perspective that genuinely adds value in every client interaction.”
