Investment managers and fund sponsors are the providers that convert capital allocation decisions into specific exposures. They may manage public equity portfolios, bond mandates, hedge funds, private equity funds, venture capital funds, real estate vehicles, private credit strategies, co-investments, or access vehicles. For a family office, the issue is not whether these providers are talented. The issue is whether each provider fits the family’s mandate, risk tolerance, liquidity needs, tax profile, governance model, and reporting requirements.
This chapter focuses on how family offices should engage investment managers professionally. Manager access can be valuable, but access alone is not strategy. The family office must maintain discipline around manager selection, allocation sizing, concentration limits, reporting, and ongoing monitoring. The best families are attractive investors because they are thoughtful, patient, organized, and clear about what they expect.
A manager roster should be designed, not accumulated. Over time, many families collect funds through banker introductions, peer referrals, legacy relationships, and one-off opportunities. The result can be an expensive and confusing portfolio with overlapping exposures and unclear accountability. The family office should instead define what role each manager plays before capital is committed.
10.1 Public Market Managers and Separately Managed Accounts
Public market managers: Firms or teams that manage portfolios of publicly traded securities, including equities, fixed income, exchange-traded funds, mutual funds, and multi-asset strategies. They may operate through commingled funds, model portfolios, advisory accounts, or separately managed accounts.
Separately managed account: A portfolio of securities owned directly by the family or entity and managed by an external manager under agreed guidelines. SMAs are often attractive to family offices because they offer transparency, customization, tax management, and control over restrictions. A family may exclude certain sectors, manage concentrated stock exposure, harvest losses, align with estate planning needs, or coordinate portfolios across trusts and entities.
Public market managers are easiest to compare because performance, risk, fees, holdings, liquidity, and benchmarks are usually available. That does not make selection easy. The family office should understand whether a manager’s returns come from skill, factor exposure, sector bias, market beta, leverage, concentration, or luck. It should also evaluate tax efficiency, trading behavior, capacity, team stability, and consistency of process.
Public market mandates should be documented. The mandate should define benchmark, risk limits, eligible securities, tax constraints, cash limits, turnover expectations, reporting frequency, and termination triggers. Without written guidelines, even a high-quality manager can drift away from the role the portfolio requires.
10.2 Private Equity, Venture Capital, Hedge Fund, Real Estate, and Private Credit Managers
Alternative investment managers: Managers who invest in less liquid, more specialized, or less transparent strategies than traditional public stocks and bonds. These include private equity, venture capital, hedge funds, real estate, private credit, infrastructure, natural resources, and special situations.
Private equity managers typically seek control or influence in private companies, improve operations, and exit through sales, recapitalizations, or public offerings. Venture capital managers invest in early-stage or high-growth companies where losses may be frequent but successful investments can drive most of the return. Hedge fund managers use flexible strategies that may include short selling, derivatives, leverage, arbitrage, event-driven positions, macro views, or relative value trades.
Real estate managers may focus on core income assets, value-add redevelopment, opportunistic development, distressed assets, sector-specific strategies, or operating platforms. Private credit managers lend to companies, projects, or assets, often seeking income, downside protection, and negotiated terms. Each alternative category has different return drivers, liquidity constraints, valuation practices, and operational risks.
Family offices are often well suited to alternatives because they may have long time horizons and can tolerate illiquidity. However, alternatives can create complexity quickly. Capital calls must be forecast, valuations may lag, fees can be layered, tax reporting may arrive late, and documents may contain restrictions that are hard to change. The family office should avoid building an alternative portfolio through isolated subscriptions. It should define commitment pacing, vintage diversification, strategy limits, manager limits, liquidity reserves, and reporting standards before committing.
Alternative managers should also be evaluated on behavior under stress. Families should ask how the manager handled prior downturns, broken deals, investor communication, valuation write-downs, covenant breaches, liquidity pressure, and team departures. A manager’s discipline is most visible when conditions are difficult.
10.3 Co-Investment Platforms, Feeder Funds, and Access Vehicles
Co-investment: An investment made alongside a fund sponsor or lead investor into a specific company, property, loan, or transaction. Co-investments may reduce fee burden, increase exposure to attractive deals, and give the family more visibility into underlying assets. They can also increase concentration and require faster diligence than fund commitments.
Feeder fund: A vehicle that pools capital from investors and invests into a larger underlying fund or strategy. Feeder funds can provide access to managers, lower minimums, administrative convenience, or jurisdiction-specific structuring. They can also add fees, reporting delays, tax complexity, and another layer of documents.
Access vehicle: A platform or structure that helps investors reach managers, funds, co-investments, or private deals that might otherwise be unavailable. These platforms can be useful, especially for smaller or newer family offices. The family office should still diligence the underlying investment, the platform, the sponsor, the custody arrangement, fee layers, investor rights, and exit mechanics.
Co-investments and access vehicles are most dangerous when they create the feeling of privileged access without adequate process. A family may be told that an opportunity is scarce, relationship-driven, or closing quickly. Scarcity can be real, but it should not suspend diligence. The family office should predefine who can approve co-investments, what information is required, how conflicts are reviewed, and how each deal fits the portfolio.
Access should also be compared with administrative burden. A small feeder position can create tax filings, capital notices, side letters, valuation updates, and document retention work that outlasts the excitement of the original allocation. The family office should know the full operating cost of every vehicle.
10.4 Manager Diligence, Allocation Sizing, and Concentration Limits
Manager diligence should combine investment review, operational review, legal review, tax review, and fit assessment. A strong return history is not enough. The family office must understand how returns were generated, whether the process is repeatable, what risks were taken, and whether the manager’s organization can continue executing the strategy.
Investment diligence: Evaluation of philosophy, strategy, edge, portfolio construction, risk management, performance attribution, benchmark relevance, team quality, and decision process. The family office should look for a clear explanation of why the manager should outperform or diversify the portfolio after fees and taxes.
Operational diligence: Review of controls, valuation policies, cybersecurity, service providers, compliance, trade operations, conflicts, business continuity, and error handling. Many investment losses originate from operational weakness rather than investment thesis failure.
Allocation sizing: The decision about how much capital to place with a manager or strategy. Sizing should reflect conviction, liquidity, volatility, downside risk, correlation, transparency, fees, tax impact, and the family’s existing exposures. A compelling manager can still be the wrong size. New managers, opaque strategies, illiquid funds, and highly concentrated vehicles should usually begin with conservative sizing.
Concentration limits: Predefined boundaries on exposure to a manager, strategy, asset class, sector, geography, counterparty, currency, vintage year, or underlying company. These limits prevent the portfolio from becoming unintentionally dependent on one judgment, one market environment, or one relationship. They also help the family office say no when a favored sponsor offers repeated opportunities.
The family office should document every manager decision. The memo should state the purpose of the allocation, diligence findings, key risks, expected role, fees, liquidity terms, tax considerations, alternatives reviewed, and review triggers. This memo becomes valuable when staff changes, markets move, or family members ask why a manager was selected.
10.5 Investment Manager Monitoring Checklist
Manager selection is only the beginning. Ongoing monitoring determines whether the family office remains an informed owner of the allocation. Monitoring should be scheduled, evidence-based, and proportional to the risk and size of the relationship.
Each review should begin with the original reason for hiring the manager. A manager should not be retained because the relationship is familiar, the reporting is polished, or exit feels inconvenient. The office should compare actual behavior against the original thesis and decide whether patience is warranted.
A practical monitoring checklist should include:
- Performance: Is performance consistent with the mandate, benchmark, peer group, and stated strategy?
- Attribution: What actually drove returns, and were those drivers expected?
- Risk: Have exposures, leverage, liquidity, concentration, or drawdown patterns changed?
- People: Have key decision-makers, analysts, partners, or operations leaders departed?
- Process: Has the manager drifted from the strategy originally approved?
- Fees: Are management fees, incentive fees, fund expenses, transaction costs, and platform fees still justified?
- Operations: Have there been control issues, restatements, valuation concerns, compliance events, or reporting delays?
- Communication: Does the manager communicate candidly, especially during difficult periods?
- Fit: Does the allocation still serve the family’s current mandate, liquidity needs, and risk profile?
Monitoring should lead to decisions. The family office may maintain, add, reduce, redeem, pause new commitments, move to a watch list, or terminate the relationship. Termination criteria should be defined in advance where possible. Examples include persistent underperformance without explanation, strategy drift, undisclosed conflicts, weak communication, excessive asset growth, key-person departures, or operational failures.
This discipline also protects continuity when the family’s objectives or leadership change later.
A disciplined family office does not chase every top-performing manager or accept every exclusive opportunity. It builds a manager roster with purpose, balance, transparency, and governance. The family’s capital should be treated as scarce. Every manager must earn a role in the portfolio, continue earning that role over time, and be replaceable when the evidence changes.
