Zombie funds and tail-end portfolio companies: the options when no buyer is near
Tail-end portfolio companies in a zombie fund usually have six routes: a continuation vehicle, a secondary sale, a recapitalization, a sale at a reset price, holding for cash, or an orderly wind-down. A one-time data license adds another: cash into the company with no change of ownership, subject to board, lender and fund approvals.
What a zombie fund is, and why the options narrow
A zombie fund is an informal label, not a legal category, for a private equity fund past its planned life that still holds portfolio companies with no near-term exit, often while running on term extensions. For a tail-end company in that position the realistic routes are a continuation vehicle, a secondary sale, a recapitalization, a sale at a reset price, holding for cash or an orderly wind-down. A one-time data license is a different kind of option: cash into the company with no change of ownership.
The backlog behind these funds is large. Bain's Global Private Equity Report 2026 counts about 32,000 unsold companies worth $3.8 trillion, puts buyout holding periods at exit at around seven years against five to six in 2010-2021, and notes distributions as a share of NAV below 15% for four years. PitchBook looks at the same problem from the other side: the median holding period of US PE-backed companies still in portfolios reached 3.4 years at the end of 2024, the longest in over nine years, with more than 30% held at least five years. One figure measures exits and the other measures companies still held, so do not compare them directly.
For private equity operating partners, the result is a portfolio tail that needs a plan even when no buyer is in sight. The guide to extended hold periods covers the wider playbook; this page compares the options for the oldest assets.
The options for a tail-end portfolio company
| Option | What happens | Ownership change | Where the cash goes | Main approvals |
|---|---|---|---|---|
| Continuation vehicle | The GP moves the company into a new vehicle; existing LPs sell or roll | At fund level | Selling LPs | LPAC, LP elections, often a fairness opinion |
| LP-led or strip secondary | LPs sell fund interests or a slice of the portfolio | At fund level | Selling LPs | GP consent under the LPA |
| Dividend recap or fund-level loan | The company or fund borrows against value | None | Fund, then LPs | Lenders, board, LPA limits |
| Sale at a reset price | A strategic, sponsor or management buyer acquires the company | Company level | Fund, then LPs | Board, lenders, LPAC if conflicted |
| Hold and run for cash | The company pays down debt and distributes when it can | None | Lenders first, then the fund | Board and credit agreement |
| Orderly wind-down or asset sale | Operations close or assets are sold off | Assets move | Creditors, then equity | Board, lenders, sometimes a court |
| One-time data license | The company licenses an agreed records dataset for AI training | None; the company keeps ownership | The company | Board, lenders, fund documents |
How a data license works for a tail-end company
The license is a contract between the portfolio company and a buyer; the fund and its LPs stay where they are. The sequence runs like this.
- The company applies, or a partner introduces it, through SourceX.
- SourceX checks fit: 50+ full-time employees at peak (contractors excluded), years of documented operations, breadth of data and rights to license it.
- The company inventories its systems and history without moving any records.
- Price and terms are agreed; the company gets one all-in price with SourceX's fee included and no separate charges.
- AI labs and data buyers review the opportunity; once a company is deal-ready, buyers typically respond within about two weeks.
- After signing, data is prepared under the agreed redaction rules and delivered, and the one-time payment typically arrives within about 60 days of invoicing once the buyer selects the data.
The license is typically exclusive for AI training over an agreed term, and the company is not bound by anything until it signs. Status alone does not rule a company out: one that is still operating, has been acquired or is winding down can qualify, as long as the data still exists.
Approvals when the fund is near the end of its term
| Approval | Who gives it | What to prepare |
|---|---|---|
| Portfolio company board | Directors, under the company's governance documents | Scope, price, exclusivity, data handling and a conflicts note |
| Lenders | The agent and required lenders, where the credit agreement restricts IP licenses or dispositions | Lender counsel's reading of disposition and collateral clauses |
| Fund governance | The GP, and the LPAC where a conflict arises, such as an affiliate earning a referral reward | A conflicts memo; the fee offset guide lists the questions |
| Fund term | The GP, under the LPA's extension and wind-up provisions | Confirmation that the fund may still approve new material contracts at its companies |
| Co-investors and management equity | Holders with consent rights | Shareholder agreement review |
| Customers and employees | Not an approval, but a rights check | What contracts, privacy policies and notices promised |
This is general information, not legal, tax or financial advice. Confirm the approvals your fund and company documents require with fund counsel.
What it means for the exit you still want
A license is not a substitute for a sale, and it does not fix a broken capital structure. It can do three useful things for a tail-end asset. It brings cash into the company without issuing equity. It produces a documented inventory of systems and history, which a later buyer's diligence team may also ask about. And it can preserve archives that cost cutting might otherwise destroy; the guide to PE digital transformation shows how to review an archive before a modernization project retires it.
The exclusive term has to be disclosed to any later buyer, as set out in how to disclose a data license in M&A due diligence. If an exit is plausible within a year, agree the order with the deal team; the guide on when to start preparing a portfolio company for exit helps with timing.
Limits and open questions
- It is one-time cash, not run-rate earnings. Expect valuation work to treat it as non-recurring, and confirm the accounting with your auditors.
- Cash reaches LPs only through permitted distributions. Proceeds land in the company, and credit agreements may require prepayment or limit distributions.
- Not every tail asset qualifies. Companies below the headcount baseline, companies whose data is mostly consumer or health information without a licensing basis, and companies whose records belong to their clients are poor fits.
- Wind-downs destroy evidence. If systems are already being retired, preserve exports first; deleted archives cannot be licensed.
- Market figures describe the market. Bain's and PitchBook's numbers say little about your fund's position, and they measure different things.
What to say to the fund CFO or portfolio CEO
Next step
Run the oldest companies in the fund through the company fit checker, a preliminary, non-binding screen. If one fits, register as a partner once fund counsel has cleared the fee question, or have the CEO apply directly at sourcex.si/apply.
Partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company. The reward is payable only after the buyer pays and SourceX receives its fee, it is never deducted from what the company receives, and no reward is guaranteed.

- Step 3Buyer selects and paysThe buyer selects and pays for the data and SourceX receives its fee.
- Step 4You get your rewardYour share of SourceX fees becomes payable.
Common questions
Is zombie fund a legal or regulatory term?
No. It is industry shorthand for a fund past its planned life that still holds assets it has not been able to sell, often while charging fees through extensions. The legal position is set by the fund's limited partnership agreement, including its term, extension and wind-up provisions, and any LP or LPAC consents those require. Read those documents rather than relying on the label.
Can a fund in its extension period approve a new license at a portfolio company?
Often, because the license is signed by the portfolio company, not the fund, and approved by the company's board. The fund's documents may still limit what the GP can approve during an extension or wind-up, and a conflict, such as an affiliate earning a referral reward, may need LPAC review. Fund counsel should confirm both points before the company signs anything.
Does license cash go straight to LPs?
No. The payment goes to the portfolio company, which licenses the records and keeps ownership of them. Moving cash from the company to the fund depends on the credit agreement's prepayment and distribution terms, the board's approval and the company's solvency. In a leveraged company, lenders may have the first claim on one-time proceeds, so check the restricted payments and disposition clauses early.
Will a data license make a tail-end company harder to sell later?
Not necessarily. A later buyer will want to see the executed agreement, the exclusive term and any obligations that survive it, and some buyers will care if they planned to use the same records themselves. Because the license is time-limited and the company keeps ownership, the main task is clear disclosure, and the inventory the license required may help answer the buyer's diligence questions.
What happens to a company's records if it is wound down?
It depends on who controls the assets and what the wind-down plan says. Records are often lost when subscriptions lapse, servers are recycled or assets are sold without anyone considering the archive. A company winding down can still qualify for a license if the data exists and the people controlling the assets are involved, so preserve exports before systems are retired.
