Zombie Fund

Definition

A private equity or venture capital fund that continues to operate beyond its intended life, holding illiquid portfolio companies that have neither achieved exit nor been written off. Zombie funds present governance challenges, carry ongoing management costs, and often reflect unrealised intangible asset potential that has failed to convert into realisable value.

Complementary Terms

Concepts that frequently appear alongside Zombie Fund in practice.

Fund of Funds (FoF)

An investment vehicle that allocates capital to a portfolio of private equity, venture capital, or hedge fund managers rather than investing directly in companies. Fund of funds provide diversification across managers, strategies, and vintages, though they involve an additional layer of management fees and carried interest.

Fund Vintage

The year in which a private equity or venture capital fund makes its first investment or its final close. Vintage year is used to group and compare fund performance because macroeconomic conditions at the time of investment significantly influence returns.

J-Curve

The pattern of returns typically experienced by private equity and venture capital funds, where early years show negative returns (due to fees and unrealised investments) before turning positive as portfolio companies mature and generate exits. The shape of a fund's J-curve reflects its deployment pace and value creation speed.

Co-Investment

A direct investment made by a limited partner alongside a private equity or venture capital fund in a specific portfolio company. Co-investments allow LPs to increase exposure to particular deals, typically at reduced or no management fees and carry, while giving the GP additional capital for larger transactions.

Total Value to Paid-In (TVPI)

A private equity and venture capital performance metric combining both realised returns (distributions) and unrealised value (remaining portfolio value) relative to total capital contributed. TVPI equals DPI plus RVPI and provides the most complete picture of a fund's overall performance.

Vintage Diversification

An investment strategy that spreads private equity or venture capital commitments across multiple fund vintage years to reduce the impact of any single economic cycle on portfolio performance. Vintage diversification is a core principle of institutional portfolio construction and helps smooth the J-curve effect inherent in illiquid fund investments.

Series A / B / C

Sequential rounds of venture capital financing that follow the seed stage. Series A typically funds scaling after product-market fit; Series B accelerates growth and market expansion; Series C and beyond fund further scaling, internationalisation, or pre-IPO preparation.

Vintage Year

The year in which a private equity or venture capital fund makes its first investment or first capital call, used to classify and compare fund performance across different economic and market cycles. Vintage year analysis is essential for benchmarking because funds launched in different years face different entry valuations, exit environments, and macroeconomic conditions.

PE funds buy companies at entry multiples, operate them to improve cash flows and competitive position, then exit at higher multiples — valuations are critical for entry/exit decisions.
