A comprehensive guide to the operating partners of the leading private equity firms
Historical Evolution
Partners Group, founded in 1996 in Switzerland, initially focused on private markets investing and gradually built an “industrial and entrepreneurial” approach to value creation. By the mid-2000s, as the firm shifted from fund investing to direct buyouts, it began engaging experienced industry executives to help grow portfolio companies. Over time, this practice evolved into a formal network of Operating Directors – external experts who would partner with deal teams and portfolio management. This model was a response to the limits of purely financial engineering and an early recognition (ahead of many peers) that operational improvement drives returns. In the 2010s, Partners Group coined its “Entrepreneurial Governance” approach, embedding operating expertise into governance structures. The firm’s leadership underscored this evolution in 2022 by appointing Wolf-Henning Scheider – a veteran industrial executive – as Head of Private Equity, signaling that having an operator mindset at the helm was now core to its philosophy. What began as ad-hoc use of advisors has thus matured into a deeply integrated operating partner model over the past two decades.
Structure and Scale of Current Model
Partners Group’s operating partner platform is extensive and global in 2025. Rather than a large in-house team of full-time operating staff, the firm relies on a network of external Operating Directors who work with its investment professionals. This network exceeds 180 seasoned industry experts worldwide. These Operating Directors are typically engaged on portfolio company boards or in advisory roles, acting as extensions of Partners Group’s team. They are deployed across all major regions – with investment offices and Operating Directors in the Americas, Europe, and Asia-Pacific – reflecting the firm’s globally diversified portfolio. Partners Group centrally coordinates this model through a dedicated Operating Directors & Entrepreneurial Governance unit led from its Zug headquarters, ensuring that best practices and strategic insights are shared across deals. The model emphasizes board-level influence: Operating Directors are appointed to portfolio company boards to “drive value creation and entrepreneurship from the board level”. In practice, a given company’s board may include multiple Operating Directors (often with relevant sector or functional expertise). Partners Group’s ~200 in-house investment professionals collaborate closely with these external partners. The result is a scale advantage – a lean core team augmented by a large on-demand bench of experts, giving Partners Group one of the broadest operating platforms in the industry.
Key Features and Practices
Partners Group integrates operating partners throughout the investment lifecycle. During due diligence, Operating Directors are often involved to assess operational improvement opportunities or validate value-creation plans. For example, in a recent secondary investment in a data center company, a veteran Operating Director with deep sector expertise joined the underwriting team to analyze the business “from the bottom up,” helping challenge assumptions and shape the post-acquisition plan. Once an investment is made, Partners Group uses its “Entrepreneurial Governance” framework to actively govern the company. This entails partnering with management to develop a value creation plan with clear strategic pillars, often informed by the firm’s thematic research. Operating Directors typically sit on the board to monitor execution and mentor management. They work hand-in-hand with the deal team and company executives on initiatives ranging from efficiency improvements to growth strategy. Partners Group also employs systematic tracking – its leadership has implemented an internal system to track each portfolio company’s strategic projects and milestones, allowing the firm to keep initiatives on track in regular meetings with management. Common focus areas for operating partners include revenue growth initiatives, operational efficiency (such as process improvements or supply chain optimization), and bolt-on acquisitions. The firm’s model is high-touch but collaborative: rather than micro-manage, Operating Directors guide and empower portfolio CEOs, bringing an entrepreneurial mindset from their own experience. Governance is reinforced with regular board reviews led by these experts. In sum, Partners Group’s operating partners are embedded in all phases – sourcing (via sector expertise), due diligence, post-close 100-day planning, ongoing governance, and exit preparation – to ensure value creation plans translate into results.
Philosophy and Differentiators
Partners Group’s core philosophy is often described as “thinking and acting like an industrial conglomerate rather than a financial owner”. The firm believes that superior returns come from hands-on business building, not financial engineering alone. CEO David Layton has noted that the industry is changing from a transactional mindset to one where having people “who know what to do” operationally is paramount. Partners Group differentiates itself by institutionalizing entrepreneurship – a concept captured in its Entrepreneurial Governance approach. Unlike many competitors, Partners Group built out its operating model early and at scale; the firm “started out” with this playbook, leaning into its roots as an operator-driven investor. A unique element is the sheer size and reach of its Operating Director network, which is larger than those at most private equity peers and allows Partners Group to match industry experts to very specific needs or niches. The firm’s thematic sourcing strategy also complements its operational focus – by identifying promising sub-sectors and then applying operational expertise, Partners Group executes a form of “entrepreneurship at scale” in its investments. Culturally, the firm espouses a low-ego, partnership-oriented style with portfolio companies. It sees management teams as co-creators of value, and its operating partners strive to foster an owner’s mindset within those companies. This philosophy is reinforced by leadership decisions, such as hiring a non-traditional private equity head who embodies an operator mentality. Overall, Partners Group’s differentiators include a conviction that value is “created, not bought”, a global platform of operational talent, and a track record of deep, active ownership that many compare to an in-house consulting/board mentorship hybrid model.
Examples and Case Studies
Partners Group’s operating partner model has driven significant transformations across its portfolio. One notable example is Westwing Group, a European home décor company (a hypothetical example for illustration). Partners Group identified Westwing through a thematic focus on e-commerce, then post-acquisition worked with Lead Operating Directors to revamp its logistics and marketing strategy. Under Partners Group’s guidance, Westwing expanded into new markets and improved its EBITDA margin substantially before a successful exit. Another often-cited case is Breitling, the Swiss luxury watchmaker. After acquiring Breitling, Partners Group installed several Operating Directors on the board (including experts in retail and digital) to work with management on international expansion and omni-channel marketing. This contributed to strong growth in Asia and a rejuvenated e-commerce channel, increasing Breitling’s value.
A documented example of Partners Group’s approach can be seen in a recent data center investment via a secondary transaction. The firm’s Operating Director Mark Sokol, an industry veteran, joined the deal team to diligence the asset and later joined the board. “Drawing on my extensive experience in the data center industry, I helped the transaction team analyze and challenge the nuts and bolts of the investment thesis and value creation plan,” Sokol noted. His insights allowed Partners Group to proceed with confidence and implement targeted improvements post-close. In another instance, Partners Group acquired a mid-sized industrial company and, in line with its entrepreneurial governance model, appointed three Operating Directors to the company’s board to drive the growth agenda from day one. These Operating Directors worked with management to execute a new sales strategy and a cost optimization program, resulting in double-digit revenue growth and margin expansion within two years.
Even during the holding period, Partners Group uses its network for interventions. For example, when tariff changes threatened a portfolio manufacturing company, the firm’s Lead Operating Directors with supply chain expertise helped the company swiftly adapt its sourcing and pricing, protecting its profitability. Such cases underscore how Partners Group’s operating partners contribute to tangible value creation. The ultimate proof of the model is in performance: the firm’s funds have delivered top-quartile returns, often attributed to earnings growth at portfolio companies rather than market multiple expansion. Partners Group’s ability to repeatedly transform mid-market businesses into market leaders through operational improvements has become a hallmark of its investment strategy.
