The first structural decision you make as a fund manager is whether to raise capital through a traditional fund or a special purpose vehicle. This choice affects your economics, your regulatory obligations, your investor relationships, and how you run your day-to-day operations. Getting it wrong means restructuring mid-raise or living with a vehicle that does not fit your strategy.
This guide breaks down the practical differences between funds and SPVs, when each structure makes sense, and the common mistakes managers make when choosing between them.
What Is a Traditional Fund
A traditional fund is a pooled investment vehicle, typically structured as a Delaware limited partnership. Investors (limited partners) commit capital to the fund, and the general partner deploys that capital across multiple investments over a defined investment period, usually three to five years.
The GP has discretion over which investments to make. LPs do not approve individual deals. Capital is called from LPs as needed, not contributed all at once. Returns are distributed as portfolio companies exit or generate cash flows, following a waterfall defined in the Limited Partnership Agreement.
Key characteristics of a traditional fund
- Blind pool: investors commit capital before specific investments are identified
- Multi-deal: the GP deploys capital across a portfolio of investments
- Capital calls: LPs fund their commitments over time as the GP identifies opportunities
- Fund term: typically 10 years with extension provisions
- Economics: management fee (usually 2% of committed capital) plus carried interest (usually 20% of profits above a preferred return)
A traditional fund works best when you want discretion over capital deployment, plan to make multiple investments, and need the flexibility to build a diversified portfolio over time. It is the standard structure for venture capital funds, private equity buyout funds, and most hedge fund strategies.
What Is an SPV
A special purpose vehicle is a single-deal entity. It is formed for one specific investment, raises capital for that investment, and terminates when the investment is realized. Investors know exactly what they are investing in before they commit capital.
SPVs are typically structured as Delaware LLCs rather than limited partnerships. They are governed by an operating agreement instead of an LPA. Capital is usually contributed at closing rather than called over time, and distributions happen when the underlying investment exits.
Key characteristics of an SPV
- Known investment: investors commit to a specific deal, not a blind pool
- Single-deal: the entity holds one investment and one investment only
- Capital at close: investors contribute their full amount at or around closing
- No defined term: the SPV exists until the investment is realized
- Economics: varies, but commonly a management fee (or setup fee) plus carry on profits
Series LLCs
If you plan to do multiple SPV deals, a series LLC lets you create segregated series under a single umbrella entity. Each series is a separate SPV with its own assets, liabilities, and investors. You form the master LLC once and add new series for each deal. This reduces formation costs and administrative overhead compared to forming a new entity for every transaction.
Series LLCs are recognized in Delaware and several other states. The legal segregation between series has been tested in court, though the body of case law is smaller than for traditional LPs. If your investors include institutions, check whether their counsel is comfortable with the series structure. Some institutional LPs prefer the certainty of a standalone entity.
Side-by-Side Comparison
| Traditional Fund | SPV | |
|---|---|---|
| Investment discretion | GP chooses investments (blind pool) | Investors know the specific deal |
| Number of deals | Multiple investments over time | One investment per entity |
| Capital commitment | Called over investment period (3-5 years) | Contributed at or near closing |
| Typical entity | Delaware LP + GP LLC + Mgmt Co LLC | Delaware LLC (or series under master LLC) |
| Governing document | Limited Partnership Agreement (LPA) | Operating Agreement |
| Economics | 2% management fee + 20% carry (typical) | Setup fee or reduced management fee + carry |
| Formation cost | $15,000-$50,000+ in legal fees | $2,000-$10,000 (or less with series LLC) |
| Time to launch | 6-12 weeks (documents + fundraise) | 1-4 weeks (simpler docs + known deal) |
| Regulatory filings | Form D, Blue Sky, Form ADV, potentially Form PF | Form D, Blue Sky (per deal) |
| Best for | VC/PE managers building a portfolio over time | Deal-by-deal syndicators, co-investments, one-off opportunities |
When to Use a Traditional Fund
A traditional fund is the right choice when your strategy requires discretion over capital deployment. If you want to build a portfolio of investments over time, select opportunities as they arise, and manage the portfolio as a whole, you need a fund.
Specific scenarios where a fund makes sense:
- You plan to make 5+ investments. The overhead of forming a fund is justified when you are deploying capital across a portfolio. For fewer deals, SPVs are simpler and cheaper.
- Your LPs want portfolio diversification. Institutional LPs expect fund managers to build diversified portfolios. A blind pool gives them exposure across multiple companies, stages, and sectors.
- You want to call capital over time. Funds let you draw down commitments as you find deals, which improves IRR by reducing the time capital sits idle. SPVs require full contribution at closing.
- You want management fee income during the investment period. A 2% annual management fee on $50M in commitments is $1M per year. That funds your team, your office, and your operations. SPVs generate less predictable fee income.
- You are raising from institutional LPs. Pensions, endowments, fund-of-funds, and family offices expect the traditional fund structure. They have internal processes built around LPA review, side letter negotiation, and capital call mechanics.
When to Use an SPV
An SPV is the right choice when you have a specific deal and want to raise capital for that deal only. The economics, the investor relationships, and the regulatory obligations are all simpler than a traditional fund.
- You are syndicating a single deal. You found a company you want to invest in and want to bring in co-investors. An SPV lets each investor evaluate the specific opportunity rather than committing to a blind pool.
- You are testing a strategy before raising a fund. A few successful SPVs build your track record. They demonstrate deal flow, investment judgment, and the ability to return capital, all of which make a future fund raise easier.
- You want lower formation costs. An SPV costs $2,000 to $10,000 in legal fees. A series LLC makes subsequent deals even cheaper. If you are doing early-stage venture deals at small check sizes, fund formation costs may not make economic sense yet.
- Your investors are mostly individuals or angels. Individual investors often prefer to evaluate each deal rather than committing to a blind pool. An SPV-by-SPV model lets them opt in selectively.
- You have a co-investment opportunity alongside a fund. Many GPs run a primary fund and offer co-investment SPVs for deals that exceed the fund's allocation. This lets LPs increase exposure to high-conviction deals without increasing their fund commitment.
Hybrid Approaches
Funds and SPVs are not mutually exclusive. Many managers use both.
Fund + Co-Investment SPVs
The most common hybrid: you run a traditional fund for your core strategy and spin up SPVs for co-investment opportunities. When a deal exceeds what the fund can allocate (either by size or by concentration limits), you offer the overage to LPs through a co-investment SPV. This lets LPs get more exposure to high-conviction deals while keeping the fund diversified.
SPV Track Record, Then Fund
Many first-time managers start with SPVs to build a track record before raising a fund. You do three to five deals via SPVs, demonstrate returns, and then raise a Fund I backed by verifiable performance data. This is the most common path for emerging managers coming from operating roles, angel investing, or venture scouting.
Series LLC as Platform
If you are doing deal-by-deal investing at volume, a series LLC gives you the operational benefits of a single entity with the deal-by-deal flexibility of SPVs. You form the master LLC once, add a new series for each deal, and manage them through a single platform. This works well for syndicators doing 5-20+ deals per year.
Common Mistakes
- Raising a fund when you should start with SPVs. If you do not have a track record, a committed LP base, or a clear multi-deal strategy, a fund may be premature. The formation cost, the time to fundraise, and the management company overhead are real. SPVs let you test the waters with lower upfront commitment.
- Using standalone entities when a series LLC would save time and money. If you are doing five or more SPV deals, forming a new LLC for each one creates unnecessary paperwork, state filings, EINs, and bank accounts. A series LLC consolidates that into one entity.
- Ignoring regulatory filing requirements for SPVs. An SPV still requires a Form D filing within 15 days of the first sale of securities. It still requires Blue Sky filings in applicable states. If you are advising the SPV, it still needs to appear on your Form ADV. These are not optional.
- Overcomplicating the structure. Your first fund does not need parallel vehicles, feeders, offshore structures, or aggregator entities. Start simple. You can add complexity in Fund II if your LP base requires it. Unnecessary structure adds cost, delay, and administrative burden.
- Not planning for the transition from SPVs to a fund. If you start with SPVs and plan to raise a fund eventually, think about track record portability, existing LP relationships, and how your SPV economics will compare to fund economics. LPs will compare your SPV returns to your proposed fund terms. Make sure the story is coherent.
