Neil McNamara examines two seismic shifts in the consulting industry: the emergence of direct Big Four competitors backed by major private equity firms, and the aggressive legal responses these departures are triggering. The episode focuses on two concrete cases - EY partner WTS UK (backed by EQT) and the launch of Unity Advisors by the former head of EY UK and PwC UK's former COO (backed by Warburg Pincus) - where senior partners are now founding firms explicitly competing with their former employers rather than serving underserved niches. McNamara unpacks the tension between enforceable partnership agreements and the broader reputational and strategic risks of aggressive enforcement: PwC's legal threats, withholding deferred compensation, and stripping former partners of healthcare access raise questions about firm culture, market perception, and whether the Big Four's response risks damaging client relationships with PE firms who own competing ventures. For consulting operators, firm leaders, and career consultants, this episode reveals how consolidation and partner retention are reshaping competitive dynamics and raising stakes for how partnerships govern departures.

Key takeaways

  • →The Big Four are facing a new competitive threat from well-funded boutique startups founded by their own senior partners, marking a shift from traditional boutique firms targeting underserved markets.
  • →PwC's aggressive legal tactics against departing partners - including compensation withholding and healthcare elimination - raise questions about firm culture and how this aggressive posture appears to the market.
  • →Private equity backing of competing boutiques creates complex conflicts for Big Four firms, as their litigation against PE-backed startups may jeopardize relationships with major PE clients like Warburg Pincus.
  • →Non-compete restrictions and partnership agreements create serious handcuffs for Big Four partners wanting to leave, complicating the competitive landscape and raising questions about fairness and enforcement strategy.
  • →The departure of global practice leaders and COO-level executives to direct competitors represents a significant shift in industry dynamics that was historically rare.

Questions this episode answers

What are the two recent examples of Big Four partners launching direct competitor firms?

WTS UK, launched by a formal global practice leader at EY and backed by EQT, and Unity Advisors, launched by the former head of EY UK and former Chief Operating Officer of PwC UK, backed by Warburg Pincus.

How is PwC responding to former partners who joined Unity Advisors?

PwC is threatening legal action and taking specific action against departing partners, including withholding deferred compensation and eliminating their access to healthcare plans.

What does Neil McNamara identify as a potential risk of PwC's aggressive response to Unity Advisors?

PwC may be damaging relationships with global clients like Warburg Pincus by suing a company owned by that client, which could pose serious risk to the client relationship.

How is the current wave of Big Four partner departures different from earlier boutique firm creation?

Historically, boutique firms were founded by former Big Four partners to serve new or underserved markets; today's departures are explicitly forming firms to compete head-to-head with the Big Four itself.

What complications do Big Four partners face when leaving to start competing firms?

Partners must comply with partnership agreements and face serious handcuffs including potential legal action, withheld compensation, and other contractual consequences.

What our scoring noted

Our reviewer’s read on each dimension, with quotes from the episode.

Insight Density

8 / 20

The episode is a short solo monologue that surfaces one genuinely novel observation - the conflict-of-interest risk created when a Big Four firm sues a company owned by one of its own global PE clients - but the rest is surface-level industry commentary with no real analytical depth or density of ideas per minute.

what about the relationship with a global private equity firm like Warburg Pincus? Uh, at Warburg Pincus Size, I have to think that it's a multimillion dollar account for pretty much most of the Big four? So when you are suing a company that your global client owns that seemingly would come with some serious risk to the client relationship
Many of these former partners are retired. Many of them have very good friends that remain at their former firms. What are the current partners to take from the firm so aggressively and viciously attacking former retired partners? What does that do to a firm's culture?

Originality

8 / 20

The Warburg Pincus client-conflict angle is a legitimately under-covered and counterintuitive point not widely written about, but the rest of the commentary - non-competes are complicated, boutiques are growing, Big Four can be bullies - is well-worn industry narrative.

something else that I haven't seen written about yet, but I have to think is is involved here is what about the relationship with a global private equity firm like Warburg Pincus
Boutique firms have been founded by former Big Four partners for a number of years now, but it's only recently that they are forming firms to directly compete against the Big Four

Guest Caliber

4 / 20

This is an unaccompanied solo monologue; there are no guests at all, which structurally caps the dimension. The host has 20 years of Big Four experience and has founded his own firm, giving him some practitioner credibility, but the format eliminates any guest-caliber signal.

I do my best to call balls and strikes layered with my own personal knowledge and experience from having worked in one of these large firms for 20 years
for almost three years. I know for a fact that there were leaders at KPMG speaking to former employees and colleagues of mine

Specificity & Evidence

9 / 20

The episode names specific firms (WTS UK, EQT, Unity Advisors, Warburg Pincus), specific roles (former head of EY UK, former COO of PwC UK), and specific retaliatory actions (withholding deferred compensation, eliminating healthcare access), but provides no financial figures, deal sizes, revenue metrics, or sourced data to substantiate claims.

Unity Advisors. This is a firm that was recently launched by the former head of Eyuk and the former chief operating officer for PwC UK. They are also backed by another global private equity fund, Warburg pincus
PwC is threatening serious legal action against Unity and taking specific action against former partners that have joined Unity, including withholding, deferred compensation

Conversational Craft

3 / 20

There is no actual conversation - this is a solo editorial monologue with no guest, no follow-up dynamic, and no productive disagreement. The host raises a few rhetorical questions at the end but they go entirely unanswered and unexamined.

Well, we clearly have many more questions here than answers, but as these industry matters evolve and develop, we will continue to report, analyze and give our opinions
Does this potentially look like a firm just being a big bully and trying to come after a new startup competitor because they're concerned about the competitive landscape?

Episode notes

The consulting industry is entering a more volatile phase as the Big Four (Deloitte, PwC, EY, and KPMG) face a new kind of competition: former partners building well-funded firms designed to compete directly with them. As industry giants respond with aggressive legal action, they are forced to balance protecting their market share with broader risks around culture, talent, and long-term positioning. In this episode, Neal explores whether these hardball tactics could backfire, impacting how firms are perceived internally and by the private equity players they rely on as major clients. Listen in to hear about the shift in power that’s reshaping the industry from the inside.

Narrator: Welcome to Consulting Uncensored, the podcast that pulls back the curtain on the good, the bad and the ugly of the consulting world. This is where real conversations happen about leadership, strategy, culture and careers in consulting. Hosted by industry veteran Neil McNamara, each episode features candid discussions with consultants, executives and firm leaders who are building, challenging and reshaping the industry from the inside. No filters, no fluff, just honest insight into what actually works and what needs to change. This is Consulting Uncensored.

Neil McNamara: Here's Neil for many years now, I've been writing about the good, the bad and the ugly of the Big Four. And for those of you who are unfamiliar with that vernacular, the Big Four refers to the four largest consulting firms in the world, PwC, EY, Deloitte and KPMG. Now, some argue that I spend outsized time on the bad and the Ugly, for which one could have a rebuttal of Sometimes they make it just way too easy to go there. In all seriousness, I do my best to call balls and strikes layered with my own personal knowledge and experience from having worked in one of these large firms for 20 years. Now I'll also be interviewing guests on their personal, unique and under the tent experiences in these firms for, of course, an uncensored view, an inside look as to what it's like in the largest firms in the world that have historically dominated our industry. Today, though, I want to touch on a couple of recent events. One literally came out the day of this recording, so we'll start with that one. It was announced today that a formal global practice leader at EY is starting his own tax firm, WTS uk. Also confirming that accountants are still not creative at all in coming up with names for their firms. Name aside, this firm has been backed by one of the largest private equity funds in all of Europe, eqt. This continues the trend of senior partners leaving Big Four firms to form competing firms. Now, this is a relatively new development in our industry. Boutique firms have been founded by former Big Four partners for a number of years now, but it's only recently that they are forming firms to directly compete against the Big Four. Until recently, boutique consulting firms were formed by people that were going after either a new or underserved market. This is what I did when I found my firm. I found a firm to be completely different than the Big Four in effectively every way, from its talent strategy to its compensation to its execution model and ultimately to the end market that we were serving. Now, building a firm to compete head to head with your former firm comes with some serious complications, primarily due to the serious handcuffs that are put on Big Four partners if they ever do want to leave. Which leads nicely into the next news topic on firms being founded to compete against the Big Four, Unity Advisors. This is a firm that was recently launched by the former head of Eyuk and the former chief operating officer for PwC UK. They are also backed by another global private equity fund, Warburg pincus. Well, now PwC is threatening serious legal action against Unity and taking specific action against former partners that have joined Unity, including withholding, deferred compensation and what some are rightfully referring to as a bit petty eliminating their access to their healthcare plans. So listen, these partners sign partnership agreements and they should be compliant with these partnership agreements or deal with the consequences when they choose not to. I had to deal with this myself in founding my own firm and for almost three years. I know for a fact that there were leaders at KPMG speaking to former employees and colleagues of mine and were told to keep an eye out and ensure that I wasn't competing with the firm in any way. That said, this is much more complicated than just simple legal agreements. Many of these former partners are retired. Many of them have very good friends that remain at their former firms. What are the current partners to take from the firm so aggressively and viciously attacking former retired partners? What does that do to a firm's culture? What does this say to the market? Does this potentially look like a firm just being a big bully and trying to come after a new startup competitor because they're concerned about the competitive landscape? And something else that I haven't seen written about yet, but I have to think is is involved here is what about the relationship with a global private equity firm like Warburg Pincus? Uh, at Warburg Pincus Size, I have to think that it's a multimillion dollar account for pretty much most of the Big four? So when you are suing a company that your global client owns that seemingly would come with some serious risk to the client relationship. Well, we clearly have many more questions here than answers, but as these industry matters evolve and develop, we will continue to report, analyze and give our opinions as this is a very exciting time in our industry.
