The Product Operating Partner Model for Private Equity
Executive Summary
Private equity firms create value through capital, strategy, governance, financial discipline and active ownership.
Portfolio company management teams contribute sector knowledge, customer relationships, technical capabilities and operational experience.
However, in companies whose performance depends on physical or industrial products, a specialised capability is often missing between the investment thesis and operational execution:
The product operating layer.
SARDI PRO CAPITAL is a Product Operating Partner for private equity firms and PE-backed companies.
SARDI PRO CAPITAL works alongside investors, operating partners, boards and portfolio company teams to transform product-related opportunities into measurable improvements in:
- Gross margin
- Product-market fit
- Development speed
- Pricing power
- Competitive differentiation
- Profitable growth
- Enterprise value
SARDI PRO CAPITAL is not a private equity fund, a traditional consultancy or a design agency.
SARDI PRO CAPITAL is an execution-focused and investor-aligned product operating capability.
Its purpose is clear:
To increase the performance of invested capital through better product decisions, stronger product assets and disciplined execution.
A New Operating Capability for Active Ownership
Private equity is not passive capital.
Invest Europe defines private equity through its combination of finance and active ownership, with investors supporting portfolio companies throughout their growth journey.
Operating partners have consequently become increasingly important throughout the investment lifecycle.
PwC describes the operating partner or operating team as a capability that supports portfolio companies through the value creation plan, from pre-diligence to exit. PwC also emphasises the importance of making management teams genuine partners in value creation.
The logic is straightforward:
Capital provides potential.
Execution converts that potential into investment performance.
Private equity firms have already developed specialised operating resources in areas such as:
- Finance
- Commercial excellence
- Procurement
- Technology
- Data
- Artificial intelligence
- Human capital
- Supply chain
- Organisational transformation
Product-centred companies require an equivalent operating capability focused on the complete product system.
That system includes far more than product design.
It includes:
- Market relevance
- Customer and stakeholder needs
- Product strategy
- Product architecture
- Materials and components
- Manufacturing decisions
- Development processes
- Product economics
- Portfolio complexity
- Technical feasibility
- Product intelligence
- Future growth platforms
These variables directly influence the financial outcomes followed by investors.
What Is a Product Operating Partner?
A Product Operating Partner is a specialist value creation partner that works with private equity firms and portfolio company management teams to identify, prioritise and execute product-related improvements.
The Product Operating Partner connects four domains that are frequently separated:
- The investment thesis
- The market
- The physical product
- Operational execution
This connection is important because product decisions often precede their financial consequences by months or years.
A product architecture decision can affect future gross margin.
A weak roadmap can affect revenue growth.
Excessive product complexity can increase inventory, engineering and service costs.
A poorly understood customer need can lead to development expenditure without market relevance.
A strong product platform can create several years of scalable growth.
The Product Operating Partner gives the investor greater visibility and control over these variables.
SARDI PRO CAPITAL Is Not the Capital Investor
The distinction between investment and operating responsibility is fundamental.
SARDI GROUP is a capital investor.
SARDI PRO CAPITAL is not the capital investor.
SARDI PRO CAPITAL operates as the specialist Product Operating Partner serving investors and portfolio companies.
This separation creates a clear operating architecture:
SARDI GROUP
SARDI GROUP can deploy capital and participate in investment opportunities through its own investment activities.
SARDI
SARDI provides industrial product strategy, innovation, design and development expertise.
SARDI publicly describes its work as strategic design advisory for industrial machinery, automation, manufacturing equipment, scientific instruments and medical devices, with experience across more than 350 industrial equipment projects and other advisory engagements.
SARDI PRO CAPITAL
SARDI PRO CAPITAL applies specialised product capabilities to the objectives, governance and investment horizons of private equity firms and their portfolio companies.
SARDI PRO CAPITAL does not present itself as the owner of the capital.
SARDI PRO CAPITAL works for capital.
That is also the meaning of the name:
PRO means “for”, “in support of” and “in the interest of”.
SARDI PRO CAPITAL means SARDI for Capital.
Skin in the Game Without Role Confusion
SARDI PRO CAPITAL’s skin-in-the-game business model does not mean that SARDI PRO CAPITAL must act as the capital investor.
It means that SARDI PRO CAPITAL can connect part of its economic compensation to agreed execution milestones, operating indicators or value creation outcomes.
Depending on the engagement, the commercial structure may combine:
- Professional fees
- Defined execution milestones
- Performance-linked compensation
- Success-based components
- Longer-term participation structures
The exact model depends on the mandate, measurability of the initiative, allocation of responsibilities and governance agreed with the investor and portfolio company.
This distinction matters.
A traditional supplier is paid principally for delivering work.
A traditional consultant is paid principally for analysis, recommendations and professional time.
A Product Operating Partner with skin in the game accepts a stronger connection between compensation and execution outcomes.
However, alignment does not eliminate discipline.
A credible skin-in-the-game structure requires:
- A documented baseline
- Explicit objectives
- Measurable indicators
- Clearly allocated responsibilities
- Realistic time horizons
- Transparent reporting
- Appropriate governance
- Recognition of external factors
Skin in the game is therefore not a slogan.
It is an operating and commercial design choice intended to improve alignment.
Not Designers
SARDI PRO CAPITAL uses design expertise, but SARDI PRO CAPITAL is not a design agency.
A design agency is generally engaged to create or redesign a defined product, interface, brand or experience.
Its mandate usually begins with a brief and ends with a deliverable.
SARDI PRO CAPITAL begins with the investment thesis.
The relevant questions are different:
- Which product decisions can increase enterprise value?
- Where is product-related margin being lost?
- Which customer needs deserve investment?
- Which product lines should grow, change or disappear?
- Which product assets can create pricing power?
- Which development programmes should be accelerated?
- Which programmes should be stopped?
- Which product capabilities will matter at exit?
- Which product risks are invisible in the financial reporting?
Design can form part of the answer.
Design is not the definition of the mandate.
Not Traditional Consultants
SARDI PRO CAPITAL uses strategic analysis, but SARDI PRO CAPITAL is not a traditional consultancy.
Traditional consulting engagements often concentrate on:
- Diagnosis
- Benchmarking
- Strategic recommendations
- Organisational design
- Presentation of an implementation roadmap
These activities can be valuable.
The Product Operating Partner model goes further.
SARDI PRO CAPITAL can remain involved in:
- Product intelligence
- Opportunity definition
- Product strategy
- Concept development
- Product architecture
- Design-to-value
- Prototype development
- Engineering coordination
- Supplier integration
- Validation
- Industrialisation
- Product launch preparation
- Performance measurement
Kearney identifies product innovation, product design and the discovery of hidden product value as relevant capabilities for private equity investors.
SARDI PRO CAPITAL integrates those capabilities within an investor-aligned operating model rather than treating them as isolated design or consulting assignments.
The difference is not simply what SARDI PRO CAPITAL recommends.
The difference is what SARDI PRO CAPITAL helps make operationally real.
Not a Parallel Management Team
SARDI PRO CAPITAL does not exist to work around portfolio company management.
SARDI PRO CAPITAL works hand in hand with management.
This is not merely a matter of organisational diplomacy.
Management teams possess essential knowledge:
- Customers
- Technology
- Manufacturing
- Employees
- Suppliers
- Historical decisions
- Regulatory constraints
- Commercial relationships
- Sector dynamics
The Product Operating Partner contributes a different perspective:
- Investor alignment
- Independent product intelligence
- Cross-sector product experience
- External challenge
- Structured prioritisation
- Specialist execution capacity
- Speed
- Connections between product and enterprise value
Neither side replaces the other.
The operating model combines their capabilities.
Bain describes successful portfolio value creation as the alignment of shareholders and management around priorities and a practical path to execution.
SARDI PRO CAPITAL applies the same principle to product-led value creation.
Working Hand in Hand
The relationship can involve four interconnected groups.
The Investment Team
The investment team defines the investment thesis, return objectives, holding-period priorities and capital-allocation logic.
The Operating Partner or Portfolio Team
The operating team coordinates the broader Value Creation Plan and monitors operational progress.
Portfolio Company Management
Management leads the company, owns operating decisions and mobilises internal capabilities.
SARDI PRO CAPITAL
SARDI PRO CAPITAL provides the specialist product intelligence, strategy and execution capabilities required by the investment thesis.
The model functions when information flows in both directions.
The investor gives SARDI PRO CAPITAL access to:
- The investment thesis
- Value creation priorities
- Financial objectives
- Identified risks
- Governance expectations
- Relevant reporting requirements
The portfolio company gives SARDI PRO CAPITAL access to:
- Product teams
- Technical information
- Customers and stakeholders
- Existing research
- Development processes
- Manufacturing constraints
- Supplier relationships
- Portfolio economics
SARDI PRO CAPITAL converts this access into:
- Product evidence
- Prioritised opportunities
- Product Value Creation Plans
- Product assets
- Execution programmes
- Investor-grade product intelligence
- Measurable operational progress
The objective is not to create another layer of bureaucracy.
The objective is to create a missing layer of capability.
The FORMULA SARDI Approach
SARDI PRO CAPITAL applies the proprietary FORMULA SARDI to product-led value creation.
FORMULA SARDI is a structured and evidence-led approach developed through SARDI’s experience in industrial product strategy and development.
SARDI publicly refers to FORMULA SARDI as part of the methodology and expertise developed within its product teams.
In the private equity context, the scientific mindset behind FORMULA SARDI means that product decisions are not treated as matters of taste, intuition or internal politics.
Product decisions are treated as hypotheses that must be investigated.
This requires:
- Observation
- Evidence collection
- Stakeholder intelligence
- Identification of relevant variables
- Development of alternative hypotheses
- Rapid conceptual exploration
- Technical feasibility analysis
- Economic evaluation
- Testing
- Validation
- Iteration
- Measurement
The exact tools and sequence depend on the product, market and investment thesis.
The underlying discipline remains consistent:
Assumptions must be made visible.
Relevant evidence must be collected.
Alternatives must be compared.
Product decisions must be connected to economic consequences.
Execution results must be measured.
This is particularly important in mature industrial companies, where long-standing assumptions can become confused with objective facts.
A product may exist in a certain form because of:
- A former customer
- An obsolete manufacturing constraint
- A past supplier
- An inherited technical decision
- An internal preference
- A historical market condition
FORMULA SARDI challenges these assumptions without dismissing the technical and industrial knowledge accumulated by the company.
The purpose is not disruption for its own sake.
The purpose is evidence-based value creation.
From Financial Thesis to Product Hypothesis
An investment thesis is usually expressed in financial and strategic terms.
For example:
- Increase gross margin
- Enter an adjacent market
- Accelerate organic growth
- Strengthen pricing power
- Reduce operational complexity
- Professionalise innovation
- Consolidate a fragmented product portfolio
- Prepare the company for international expansion
The Product Operating Partner converts each financial thesis into product hypotheses.
Investment thesis: Increase gross margin
Possible product hypotheses:
- The product contains functions customers do not value.
- Product architecture creates unnecessary component variety.
- Excessive customisation is reducing scale benefits.
- The company has failed to differentiate premium features.
- Several SKUs generate revenue but destroy contribution margin.
Investment thesis: Accelerate growth
Possible product hypotheses:
- The company is addressing the wrong stakeholder.
- The roadmap does not reflect emerging customer needs.
- Existing technology can be reused in an adjacent market.
- A product platform could support several market-specific variants.
- Development capacity is being consumed by low-value projects.
Investment thesis: Improve pricing power
Possible product hypotheses:
- The product’s economic value is not visible to customers.
- Differentiation exists technically but is not expressed physically.
- Product configurations are not structured around customer value.
- Premium characteristics are being offered without price segmentation.
- The sales team lacks evidence supporting value-based pricing.
These hypotheses create a bridge between financial objectives and operational decisions.
Product Intelligence for Investors
One of the most valuable functions of SARDI PRO CAPITAL is to create an independent view of the product system.
Financial reporting explains what has already happened economically.
Product intelligence can help explain why it happened and what may happen next.
SARDI PRO CAPITAL can provide visibility into:
- Product-market fit
- Product competitiveness
- Roadmap quality
- Development performance
- Product portfolio profitability
- Product complexity
- Customer relevance
- Product lifecycle risk
- Supplier and technology dependencies
- Internal product capabilities
- Emerging opportunities
- Execution barriers
This intelligence must be produced transparently and through appropriate governance.
SARDI PRO CAPITAL does not operate covertly inside portfolio companies.
SARDI PRO CAPITAL does not seek privileged or improperly obtained information.
SARDI PRO CAPITAL creates proprietary operational intelligence through authorised involvement in the product system.
That distinction protects trust between:
- Investor
- Board
- Management
- Employees
- SARDI PRO CAPITAL
The objective is not surveillance.
The objective is informed active ownership.
How the Product Operating Partner Creates Value
SARDI PRO CAPITAL can contribute across the complete ownership cycle.

A Solid Model Requires Clear Boundaries
The Product Operating Partner model becomes credible only when the roles remain clear.
SARDI PRO CAPITAL Does Not Control the Fund
Investment decisions, capital allocation and fund governance remain with the investor.
SARDI PRO CAPITAL Does Not Replace the Board
The board retains its governance and supervisory responsibilities.
SARDI PRO CAPITAL Does Not Replace Management
Management remains responsible for leading the portfolio company.
SARDI PRO CAPITAL Does Not Own Every Outcome
Company performance depends on multiple internal and external variables. Accountability must correspond to the scope of influence and execution responsibility.
SARDI PRO CAPITAL Does Not Promote Innovation Without Economic Logic
Every significant product initiative must connect to a relevant strategic or financial objective.
These boundaries make collaboration stronger, not weaker.
They allow SARDI PRO CAPITAL to act decisively without creating confusion about authority.
Why Employees Should Understand the Model
Employees may initially interpret the arrival of an external operating partner as:
- A management replacement
- A cost-cutting exercise
- A surveillance mechanism
- A criticism of existing capabilities
- Another consultant producing presentations
A well-structured Product Operating Partner mandate should communicate the opposite.
SARDI PRO CAPITAL exists to give internal teams:
- Greater strategic clarity
- Faster decision-making
- Additional specialist resources
- Access to external experience
- Better connections with customers and stakeholders
- Stronger development methods
- Improved prioritisation
- The ability to turn valuable ideas into real products
Internal knowledge remains indispensable.
The purpose is to combine that knowledge with additional product intelligence, execution capacity and investor alignment.
The best results emerge when portfolio company employees are treated as contributors to the value creation process rather than passive recipients of external instructions.
The Product Side of Investment Performance
Private equity firms possess significant financial intelligence, strategic creativity, governance capability and investment experience.
SARDI PRO CAPITAL brings corresponding depth to the product side.
That includes the ability to understand:
- What customers genuinely value
- Why a product wins or loses
- Where margins are created or destroyed
- Which development projects deserve capital
- How physical decisions affect economic performance
- Which product opportunities can become growth engines
- Which risks remain invisible in conventional reporting
- How to convert strategy into market-ready products
The two capabilities are complementary.
Private equity defines the investment objective.
Management leads the company.
SARDI PRO CAPITAL connects product evidence and execution to the value creation plan.
All three work hand in hand.
