Function, Structure, and History at the World's Top Firms
Private equity firms have increasingly embraced the Operating Partner role as a core part of their value-creation strategy. An operating partner is a seasoned executive (often an ex-CEO, COO, or industry expert) who works with portfolio companies to drive performance improvements and strategic growth. Unlike deal partners who focus on sourcing investments and financial structuring, operating partners concentrate on “operational engineering” – improving how businesses are run day-to-day.
This report provides a comprehensive overview of operating partners in private equity, including their historical emergence, global development, structural models, firm case studies, responsibilities, and contributions to value creation. Both academic insights and practitioner perspectives are incorporated to illuminate how this role has evolved into a key competitive differentiator in the private equity industry.
Historical Evolution of the Operating Partner Role
The operating partner role emerged as private equity shifted from relying mainly on financial engineering to focusing on business improvement. In the early LBO boom of the 1980s, value creation came largely from leverage and financial tactics, with only ~18% of gains attributed to operating improvements. After the late-80s buyout bust, industry veterans recognized the need for stronger operational capabilities.
By the 1990s, leading PE firms began growing recognition of the value of operational engineering, investing in managerial expertise to drive portfolio company growth in addition to cost-cutting. Carl Ferenbach of Berkshire Partners noted that in the 1990s “once we started to think about growth instead of just cash flow, we then had to think much more about strategy and management,” marking a pivotal shift in PE’s approach.
One of the pioneers was Clayton, Dubilier & Rice (CD&R), founded in 1978, which is widely recognized as one of the first adopters of the “operating partner” model. CD&R’s strategy from early on centered on partnering with experienced industry executives (like former CEO Jack Welch of GE) to lead acquisitions and improve operations. This set a precedent for bringing operating expertise into the investment process.
In the mid-1990s, TPG (Texas Pacific Group) became one of the first private equity firms to establish an in-house operations group, launching TPG Ops in 1995 to institutionalize operational value-add. Other major buyout firms followed suit around the turn of the millennium. For instance, KKR formally created its dedicated ops arm, KKR Capstone, in the late 1990s as an in-house consulting team to improve portfolio company performance. KKR Capstone (founded in 2000) was a “McKinsey-style” captive firm of operating executives working exclusively on KKR investments.
Throughout the 2000s and 2010s, the operating partner role gained prominence industry-wide. By the 2010s, operational improvements accounted for nearly half of value creation in buyouts (47% since 2010), a stark increase from the 18% share in the 1980s. Concurrently, the contribution of pure financial engineering fell from over 50% of value creation to about 25%. This shift was driven by competitive and market factors: high purchase price multiples and investor expectations meant PE firms could no longer rely on leverage or multiple expansion alone to generate returns.
Limited Partners (LPs) began demanding that GPs have credible operational expertise on hand, not just financial acumen. By the late 2010s, most large private equity firms had established some form of operating partner program, and the role had evolved from a niche experiment into a standard industry practice.
Global Development Across U.S., Europe, and Asia
The adoption of operating partners has unfolded somewhat differently across regions. The United States led the trend – U.S. buyout giants were first to add operational capabilities in the 1990s and 2000s, and the role is now firmly established. As noted, firms like KKR, TPG, Bain Capital, and Blackstone were early movers in building in-house operating teams. By contrast, Europe was slightly slower to formalize the operating partner concept, but has caught up in the past decade. European PE firms historically leaned more on financial restructuring and hired outside experts ad hoc.
Now, however, most major European GPs also utilize operating specialists to drive value. For example, London-based Permira today has a “Value Creation Team” of 25+ operational experts plus a network of senior advisers, and EQT in Scandinavia embedded operational value-add into its model from inception. The role of operating partners is more established in the US than in Europe, but the gap has narrowed significantly as European funds embrace similar practices. In fact, the rise of PE operations has become a global phenomenon – by 2020, operational engineering was regarded as critical for competitive advantage in PE across all major markets.
In Asia, the operating partner role is a more recent development. Many Asian private equity deals historically were growth equity investments with a lighter touch on operations. Additionally, local firms often lacked the scale to justify full-time operating teams, and experienced operating talent could be hard to recruit. However, as Asian PE matures and focuses more on buyouts and turnarounds, the importance of operational value creation is growing.
Large pan-Asian funds and global firms active in Asia have begun deploying operating partners in the region. Some Asian GPs prefer building in-house operational teams to support their portfolios, rather than paying steep fees for external consultants. According to industry observers, Asian PE firms have lagged behind Western peers in implementing operational changes, but they are investing in operational expertise as a means to boost returns and differentiate themselves.
In sum, while the operating partner model took root first in the U.S., it has spread worldwide – becoming common in Europe’s PE landscape and increasingly adopted in Asia as firms globalize and seek value beyond financial engineering.
Structural Models for Incorporating Operating Partners
Private equity firms have developed several structural models to integrate operating partners into their organizations. These models vary in whether operating professionals are internal or external, generalists or specialists, and how they interface with investment teams. The main approaches can be summarized as follows:
Dedicated Internal Operational Teams
Some firms create dedicated in-house teams of operating professionals, essentially an internal consulting unit focused on portfolio companies. KKR Capstone is a prime example of this model. Formed in 2000, KKR Capstone is a captive team of operating executives across North America, Europe, and Asia who work exclusively on KKR’s investments. These teams are typically full-time employees (or exclusive affiliates) of the PE firm. They engage with portfolio companies on-site, driving initiatives in revenue growth, cost optimization, and organizational improvement.
Other notable dedicated teams include Bain Capital’s Portfolio Group, a large in-house group of over 115 operating professionals spanning functional areas like product, go-to-market, talent, M&A, and more. Similarly, Vista Equity Partners (a software-focused PE firm) has its Vista Consulting Group, and L Catterton created an internal consulting arm called Catterton Vault. These internal teams function as a SWAT force that can parachute into any portfolio company as needed. Under this model, the operating partner role can span the full investment cycle – from pre-investment due diligence to hands-on execution and through the exit. The in-house team often institutes structured processes like 100-day plans and weekly KPI reviews.
A benefit of this approach is tight alignment and quick deployment, since the ops team is an integral part of the firm. For instance, KKR Capstone professionals can even be installed as interim managers or board members at a portfolio company, providing a direct link between KKR and the business. The trade-off is cost – maintaining a large full-time ops staff is expensive, so this model is most common at mega-funds that can support it (and pass some costs to portfolio companies). Nevertheless, many leading firms credit their in-house operating teams as a core differentiator in achieving consistent value creation.
External Operating Advisors and Embedded Professionals
Another model relies on external operating advisors or part-time operating partners who are not permanent employees of the PE firm. In this “Operating Executive/Advisor” model, the firm maintains a network of experienced executives on retainer, deploying them to portfolio companies or deal teams as needed. These individuals often carry titles like Operating Partner, Senior Advisor, or Industry Expert, but are essentially consultants rather than full-time staff. The Carlyle Group exemplifies this approach – Carlyle lists dozens of Operating Executives and Senior Advisors (around 27–50 at any time) who are seasoned former CEOs and sector specialists engaged on a contractual basis.
These individuals have deep sector-specific knowledge and extensive operating experience, and they are brought in by deal teams for their expertise. They advise on strategy, sit on portfolio company boards, and mentor management, but typically juggle other outside board roles or pursuits as well.
A variant of this is the functional specialist model: instead of each operating advisor being a general business leader, some firms source experts for specific functional areas (pricing, supply chain, IT, etc.) on-demand. Those experts engage with portfolios on particular projects. Because external operating partners are not on payroll, this model offers flexibility and cost-efficiency – the firm can tap the right expert at the right time without carrying them year-round. However, there is a risk of less integration and slower onboarding, since these advisors are not embedded in the firm’s culture daily. Leading PE firms mitigate this by carefully integrating advisors into the investment process (inviting them to investment committee discussions, etc.).
EQT in Europe has long leveraged an external network model at massive scale: since its foundation, EQT built a global network of 600+ “Industrial Advisors” (current/former executives and entrepreneurs) who contribute to deals and portfolio governance. They participate from deal sourcing and due diligence through board service, providing operational and strategic input without being full-time staff. This extensive network is considered “a vital part of our DNA” at EQT, giving the firm a competitive edge and flexibility in matching the right advisor to each situation.
Centralized vs. Decentralized Deployment
Private equity firms also differ in how they organize operating partners internally – whether as a centralized group or decentralized within deal teams. In a centralized model, the firm has a single operations unit (or “Centre of Excellence”) that serves all portfolios across industries. KKR Capstone and Blackstone’s Portfolio Operations Group are centralized teams: they float to whichever portfolio company or project requires help, and report up through a head of portfolio operations separate from deal partners.
Centralized teams often have cross-functional experts (finance, HR, digital, etc.) that can be assigned in a plug-and-play fashion to any investment. This fosters consistency in tools and best practices, and the team can capture learnings from one company to apply to others. For example, Blackstone’s operating group has specialized subsections for talent, data science/AI, procurement, energy savings, etc., which all portfolio CEOs can draw upon.
In a decentralized model, operating professionals are embedded within individual sector teams or regional offices, and work more closely alongside investment deal principals in that vertical. This means each deal team (say the Healthcare group or European buyout team) has its own operating partner(s) who focus only on that team’s deals. Carlyle’s approach leans this way: its operating executives are aligned by fund or sector (e.g. an Operating Executive for the Aerospace & Defense sector working with that deal team).
Decentralization can ensure the operating partner has deep domain knowledge and rapport with the deal team, effectively making them an extension of the investment team. Many mid-market PE firms adopt this approach, where a few operating partners are part of each investment group (sometimes even formally part of the GP partnership) rather than one large pooled ops team. The downside is potential duplication of resources and less ability to surge a large cross-functional squad into one portfolio company, but the upside is closer integration and sector focus.
Another dimension is whether operating partners are formally part of the fund’s leadership (partners) or serve in an advisory capacity. Some firms make operating partners full partners or managing directors of the firm, giving them investment committee seats and carried interest – this structurally elevates operations as equal to deal-making. Others keep operating professionals in an advisory role without carry, to maintain clear accountability (i.e. deal partners own the P&L, ops partners support).
As industry best practices have evolved, many firms now blend models: for example, a core in-house ops team augmented by specialist advisors for certain issues, or having a global head of operations with a network of part-time regional operating advisors. “The various models are not mutually exclusive”, as one study noted – a firm might employ some full-time operating partners while also tapping external consultants for niche projects. What matters is that the operating talent is effectively integrated into the investment process. Increasingly, PE firms are formalizing governance to ensure this integration – for instance, requiring a value creation plan at deal inception and assigning an operating partner to every deal from day one.
Responsibilities and Activities of Operating Partners
Operating partners have a broad mandate but generally focus on driving value creation in portfolio companies through hands-on involvement. Their key responsibilities and daily activities include:
- Value Creation Planning: Operating partners take the lead in formulating the value creation plan for an investment. Immediately post-acquisition (if not earlier), they work with the deal team and company management to map out strategic and operational initiatives to increase value. This often includes conducting a 100-day plan outlining quick wins and longer-term projects. They set targets (e.g. margin improvement, revenue growth, working capital reduction) and detailed roadmaps for achieving them. In practice, an operating partner might facilitate workshops with the portfolio company’s leadership to brainstorm improvement opportunities and then prioritize these into an actionable plan. They ensure that the plan is integral to the original deal thesis, aligning with what the PE firm promised investors for that deal. Throughout ownership, they update and refine the plan as needed. Essentially, operating partners act as “strategic architects” of how to unlock value beyond what was paid for, translating broad investment strategies into concrete operational initiatives.
- Hands-On Portfolio Company Support: The core of the operating partner’s day-to-day work is collaborating with portfolio company management to implement improvements. They often serve as advisors, coaches, and problem-solvers for the CEO and management team. This can take many forms: reviewing weekly performance dashboards and identifying issues, rolling up sleeves to troubleshoot plant operations or IT systems, or mentoring a new executive hire. Operating partners bring an outside perspective (“fresh eyes”) to spot issues in operations that insiders might miss. They help management teams execute on strategic initiatives, ensuring plans don’t remain theoretical. For example, an operating partner might lead a project to streamline a company’s supply chain – working with procurement staff to renegotiate contracts, optimize inventory levels, and improve logistics. In another case, they might guide a portfolio company’s sales team in implementing a new CRM system and training staff to use data analytics for better sales productivity. Facilitating operational improvements is a central task, whether it’s improving manufacturing throughput, increasing marketing ROI, or enhancing product development processes. In many instances, operating partners effectively become part of the extended management team of the portfolio company, spending substantial time on-site and even holding interim management roles if necessary to fill gaps. The balance they strike is often described as “coach versus player” – they coach the existing team to perform better, but also are willing to get “deep in the weeds” to directly drive results when needed.
- Governance and Board Participation: Operating partners frequently play a formal role in governance by taking board seats or acting as board observers on portfolio company boards. This allows them to influence the company’s direction and ensure alignment with the PE owner’s objectives. As board members, they push for high-level strategic and operational decisions that support the value creation plan – for instance, approving capital expenditures for a factory upgrade or green-lighting a new product launch that the plan calls for. They also help institute appropriate controls and performance monitoring at the board level. Many PE firms deliberately appoint an operating partner as the Chairman of the Board or lead director for their portfolio companies. In that role, the operating partner can effectively supervise management (especially if the CEO is new or if the business is underperforming) and provide mentorship. They ensure that board discussions are focused on key operational KPIs and that management is held accountable for meeting targets. In board meetings, operating partners will often present on the status of various initiatives and flag any needs for additional firm resources. Beyond formal meetings, they maintain close communication with portfolio CEOs – acting as a sounding board for strategic decisions and as an early warning system if things are off track. This governance role is crucial in private equity since the compressed ownership timeline (often 3-5 years) means the board must be very proactive in driving change. Operating partners bring the voice of operational experience to the board, balancing out the deal partner’s financial perspective.
- Talent Management and Leadership Development: A subtle but important part of an operating partner’s duties is ensuring the right people are in the right roles at the portfolio company. Many value creation plans cannot succeed without upgrades in management or additions of key talent. Operating partners often assess the portfolio company’s management team early on – identifying if a new CFO or CTO is needed, or if the current team has skill gaps. They then help recruit, using their networks to attract high-caliber candidates (indeed, operating partners often know many industry executives and can tap those contacts for portfolio roles). Furthermore, operating partners may mentor and develop existing management. For example, they might coach a first-time CEO through tough decisions or help a manufacturing VP learn and apply lean Six Sigma techniques. Some firms have operating partners specifically focused on human capital for this reason (e.g., Vista Equity’s human capital operating partners, Blackstone’s Talent Operations team). The mantra is that better people = better results, so operating partners spend significant effort on leadership alignment. In cases of underperformance, they may help make the call to replace a senior exec. Conversely, they help design incentive plans to retain and motivate key managers (stock option plans, bonus linked to performance metrics, etc.). As Hunt Scanlon (an executive search observer) notes, “operating partners are now instrumental in identifying, nurturing, and retaining top talent within portfolio companies.” By actively shaping the leadership team, operating partners create an environment conducive to executing the value agenda.
- Exit Readiness and Planning: As a portfolio company approaches the end of the PE firm’s ownership period, operating partners shift focus to preparing the business for exit (sale or IPO). This involves ensuring that all the operational improvements and growth initiatives translate into demonstrable financial results and an attractive story for buyers. Operating partners help management institutionalize the gains made, so that the company can smoothly transition to new ownership without value erosion. They might, for instance, document processes and playbooks, solidify second-level management depth, and ensure key customer or supplier relationships are on solid footing – anything that a savvy buyer would diligence. During the exit process itself, operating partners often play a role in management presentations to prospective buyers, articulating the value creation achieved and even outlining further opportunities (which boosts buyer confidence in paying a high price). They make sure the portfolio company can demonstrate sustainable EBITDA margins, revenue growth run-rate, or other metrics that were targeted. If any initiatives are mid-stream, operating partners try to get them to a proof point before exit (e.g. if a new plant is being built, have it near completion). Essentially, they polish the apple – exit planning can be seen as the capstone of the operating partner’s work on that asset. A study on PE exits noted that having operating partners involved can help ensure the company “is operating efficiently and can command the highest possible valuation” at sale. Additionally, if a sale process hits a bump (say a buyer raises a concern about maintenance procedures or IT security), the operating partner is on hand to address it authoritatively. In some cases, an operating partner may remain on the company’s board even after exit (if the buyer is agreeable) to maintain continuity. Overall, by the time of exit, a successful operating partner will have helped transform the company such that it is markedly more valuable than at entry – and exit planning ensures that value is fully realized in the transaction.
It’s worth noting that the operating partner’s role can vary by firm and situation. Some operating partners have a lighter-touch, advisory approach across several companies, while others essentially act as a full-time executive at one company for a period. But across these scenarios, the common thread is that operating partners bridge the gap between the high-level investment thesis and on-the-ground execution. They translate strategy into results by working through people, processes, and projects in the portfolio companies.
Impact on Value Creation and Competitive Differentiation
The rise of the operating partner role has fundamentally altered how private equity firms create value and compete. In the past, PE firms differentiated themselves largely by financial ingenuity (e.g. clever deal structuring or willingness to take on leverage). Today, operational capability is a key differentiator. Firms with strong operating partner programs can consistently drive higher revenue growth and efficiency in their portfolio companies, leading to better investment returns. Research indicates that the industry’s returns now depend heavily on these operational improvements – since 2010 nearly half of value creation in buyouts industry-wide comes from EBITDA growth and margin expansion (operations), far outpacing the contribution from multiple arbitrage or leverage). This reflects a new reality: “The era when PE was associated with mere financial engineering is a distant memory… private equity creates value through underlying business and operational improvements.” () (). Operating partners are the agents of those improvements.
Having a robust operating team allows a PE firm to execute more ambitious transformations in companies, which can translate to higher IRRs and MOICs on their investments. For example, a firm might buy a corporate carve-out that needs significant operational fixes – without in-house expertise, this would be risky, but with seasoned operating partners the firm can undertake the challenge confidently and potentially realize a big payoff. Academic studies have started to quantify the impact: one study found that deals led by partners with operating backgrounds tend to outperform in organic growth scenarios, whereas those led by purely financial partners do better in roll-up acquisition strategies. This suggests that having the right operational expertise can tilt the outcome in situations requiring internal value build-up. Another study in Review of Financial Studies (Acharya et al. 2013) showed that abnormal performance in PE deals is often attributable to improvements at the enterprise level (beyond sector trends or leverage), reinforcing that operational alpha is real and significant.
From a competitive differentiation standpoint, operating partners have become a way for PE firms to stand out in the eyes of both investors and deal targets. LPs now scrutinize a GP’s operational resources when deciding where to commit capital. Many institutional investors will ask: Does the firm have a credible, experienced ops team? Can they give examples of value they’ve added? A firm that can demonstrate a strong track record of operational improvement (with data and case studies attributable to their operating partners) often has an edge in fundraising. This has driven even firms that historically did not use operating partners to start building these capabilities. As ON Partners (an executive search firm) observed, “Many PE firms are struggling to differentiate themselves and are starting OP initiatives if they haven’t already in order to better compete.” In today’s market, not having an operating partner strategy can be a handicap – it might signal a reliance on old-school methods that may not suffice in a more complex, high-priced deal environment.
Likewise, in competitive deal sourcing and bidding, operating expertise can be a differentiator. When pursuing an acquisition, PE firms often pitch their ability to be a better owner for the company. Management teams and family sellers tend to prefer buyers who will not only provide capital but also help the business flourish. A PE firm that can bring in respected operating partners to meet the management team during the sale process sends a positive message. It shows the firm has concrete plans to help the business (not just cut costs or flip it). In some auctions, having a known operating guru on your deal team (for instance, a former industry CEO who would become board chair) can make your bid more attractive, even if your price isn’t the absolute highest. This is especially true in carve-outs or founder-owned businesses where the seller cares about the company’s legacy. Thus, operating partners contribute to win rate on deals by enhancing the firm’s credibility and offering “more than money” to sellers.
Another aspect of competitive edge is that operating partners enable PE firms to navigate difficult market cycles better. In downturns or crisis situations (e.g. the 2020 COVID-19 pandemic), having in-house operational talent meant firms could more swiftly stabilize companies – adjusting operations, reducing costs, pivoting business models – compared to firms that had to rely on external consultants. This agility can protect and even create value in volatile times. Indeed, a 2020 study noted that PE managers – both investment and operating partners – worked hand-in-hand to steer companies through the COVID shock, which in many cases separated the top-performing funds from the rest. The operating partner role has expanded to cover new frontiers of value creation as well, such as digital transformation and ESG improvements. For instance, some firms now have “Technology Operating Partners” or even “AI Operating Partners” (as highlighted by Korn Ferry in 2023) to help portfolio companies implement AI initiatives for competitive advantage. Early adoption of such specialized roles can differentiate a firm in tech-heavy deals.
It is important to note that as the operating partner model becomes widespread, the mere existence of operating teams is no longer unique – it’s the quality and effectiveness of those teams that differentiates. All top-quartile PE firms today claim to have strong operating capabilities, but their approaches and results vary. The best firms create a culture of true collaboration between deal partners and operating partners, avoiding silos or turf wars. They clearly define decision rights and integrate ops into investment committees. Firms that get it right have operating partners who feel like “first-class citizens” in the firm, not second-fiddle to dealmakers. This cultural integration is itself a competitive advantage – it leads to better decision-making and fewer internal conflicts hampering value creation. In contrast, if a firm has operating partners but the deal teams ignore their advice or bring them in too late, the potential isn’t realized. Thus, competitive differentiation now comes from how well a firm deploys its operating partners more than just whether it has them.
