Starting a private investment fund requires forming a legal entity, registering under a securities exemption, drafting offering documents, and building an operational infrastructure before you accept a single dollar from investors. Most domestic funds launch for $40,000 to $70,000 in initial legal and administrative costs, though that figure climbs if you add an offshore feeder structure. Here’s what the process looks like from start to finish.
Choose a Legal Structure
Nearly all private investment funds are organized as limited partnerships. This structure creates two distinct roles: a general partner (GP) who manages the fund and makes investment decisions, and limited partners (LPs) who contribute capital but have no say in day-to-day operations. LPs can only lose what they invest. The GP, by contrast, bears full liability for the fund’s obligations, which is why most GPs are themselves set up as a limited liability company rather than operating as an individual.
A typical setup involves at least three entities. First, the fund itself, structured as a limited partnership. Second, a GP entity (usually an LLC) that serves as the fund’s manager and decision-maker. Third, a management company (also an LLC) that employs the team, collects management fees, and handles operations. Some fund sponsors consolidate the GP and management company into one entity, but separating them gives you cleaner liability boundaries and more flexibility if you launch additional funds later.
Most fund sponsors form these entities in Delaware because of its well-developed body of partnership law and business-friendly court system, then register to do business in whatever state they actually operate from.
Pick a Securities Exemption
Private funds don’t register their securities with the SEC the way a public company would. Instead, they rely on exemptions under Regulation D, most commonly Rule 506(b) or Rule 506(c). The one you choose shapes how you find investors and what verification burden you carry.
Rule 506(b) prohibits any general solicitation or advertising. You cannot post about your fund on social media, run ads, or pitch at public conferences. You’re limited to investors you already have a relationship with. The tradeoff: investors can self-certify that they meet accredited investor standards. You don’t have to independently verify their financial status. You can also accept up to 35 non-accredited but financially sophisticated investors, though doing so triggers additional disclosure requirements that most emerging managers prefer to avoid.
Rule 506(c) lets you advertise freely, with no cap on how much capital you raise. The tradeoff here is significant: you must take “reasonable steps to verify” that every investor is accredited. That means collecting tax returns for the prior two years (for income-based qualification), or bank and brokerage statements within the past three months (for net-worth-based qualification). Alternatively, you can obtain written confirmation from the investor’s attorney, CPA, broker-dealer, or registered investment adviser that they verified accreditation within the past three months.
Most first-time fund managers choose 506(b) because they’re raising from their existing network and want to avoid the verification paperwork. If you plan to market broadly or use online fundraising platforms, 506(c) is the path.
Understand Who Can Invest
Under either exemption, the vast majority of your investors will need to be accredited. An individual qualifies as accredited if they have a net worth above $1 million (excluding their primary residence), or income above $200,000 individually ($300,000 with a spouse or partner) in each of the prior two years with a reasonable expectation of the same in the current year. Holders of certain securities licenses, including the Series 7, Series 65, or Series 82, also qualify regardless of income or net worth.
Entities qualify if they own more than $5 million in investments, or if every equity owner in the entity is individually accredited. Banks, insurance companies, registered investment companies, and employee benefit plans with assets above $5 million also qualify.
If your fund relies on the “investment company” exemption under Section 3(c)(7) of the Investment Company Act rather than the more common 3(c)(1) exemption, your investors must meet a higher bar: “qualified purchaser” status, which generally requires $5 million in investments for individuals or $25 million for institutions. Most emerging managers start under 3(c)(1), which caps the fund at 100 investors but only requires accredited investor status.
Draft Your Fund Documents
Three core documents govern your fund. The limited partnership agreement (LPA) is the backbone. It spells out the fund’s investment strategy, the GP’s authority, fee structure, profit-sharing arrangement (carried interest), fund term, investment period, restrictions on withdrawals, and the process for winding down. This is a negotiated contract between you and your LPs, and institutional investors will scrutinize every clause.
The private placement memorandum (PPM) is your disclosure document. It describes the fund’s strategy, risks, fees, conflicts of interest, tax treatment, and the backgrounds of the management team. Think of it as the prospectus equivalent for a private offering. A well-drafted PPM protects you legally by ensuring investors were informed before committing capital.
The subscription agreement is what each investor signs to formally commit capital. It includes representations that the investor is accredited, acknowledges the risks disclosed in the PPM, and confirms the amount of their commitment.
Hiring an experienced securities attorney to draft these documents is not optional. Template documents exist online, but fund formation is one area where cutting corners creates real legal exposure. Attorney fees for the full document package typically run $25,000 to $50,000 depending on complexity, and represent the largest chunk of your launch budget.
Register as an Investment Adviser
If you manage $150 million or more in assets, you generally must register with the SEC as an investment adviser. Below that threshold, you register with your state’s securities regulator. Some managers qualify for an exemption from registration entirely, particularly if they manage only private funds, have limited assets, and don’t hold themselves out publicly as advisers. The most common exemptions are the “exempt reporting adviser” exemptions for venture capital fund advisers and private fund advisers managing less than $150 million.
Even exempt reporting advisers still file Form ADV with the SEC, which is a public document disclosing your business, fees, disciplinary history, and conflicts of interest. Registration or exemption filing should happen before you begin accepting investor capital.
Build Your Operational Infrastructure
Investors, especially institutional ones, expect you to have professional service providers in place before they commit capital. Three are essential.
- Fund administrator: Handles net asset value (NAV) calculations, investor reporting, capital call processing, and distribution tracking. For funds investing in illiquid assets like private equity or real estate, the administrator also manages loan accounting, cash flow modeling, and covenant monitoring. Having an independent administrator signals to investors that a third party is validating your numbers.
- Fund auditor: Provides annual audited financial statements, which most LPAs require. The auditor reviews your valuation methodologies and pricing models, which becomes especially important for funds holding assets that don’t have a market price. Most institutional investors will not invest in an unaudited fund.
- Custodian: Holds the fund’s assets independently from the manager. Institutional investors increasingly scrutinize the custodial arrangement during due diligence as a safeguard against fraud or mismanagement.
You’ll also need a prime broker (if you trade public securities), a tax adviser experienced in partnership taxation, and potentially a compliance consultant to help you build your compliance manual and code of ethics.
Budget for Launch Costs
Fund sponsors should expect to spend at least $40,000 to $70,000 to get a domestic fund off the ground. That covers legal fees for entity formation and document drafting, state registration and filing fees, initial compliance setup, and the first round of administrative costs. Adding an offshore feeder fund for non-U.S. or tax-exempt investors pushes costs higher.
After year one, ongoing costs typically decline because organizational expenses are largely one-time. Recurring expenses include fund administration fees, audit fees, insurance (errors and omissions coverage), compliance costs, and legal counsel for ongoing matters. These ongoing costs usually run $50,000 to $100,000 or more per year depending on fund size and complexity.
Most fund managers cover launch costs out of pocket or through the management company, then reimburse themselves from the fund once it reaches a certain size, as specified in the LPA.
Set Your Fee Structure
The standard private fund fee model is “2 and 20”: a 2% annual management fee on committed or invested capital, plus 20% carried interest on profits above a specified return threshold. In practice, emerging managers often need to offer more favorable terms to attract early investors. That might mean a lower management fee (1% to 1.5%), a reduced carry percentage, or a preferred return (sometimes called a “hurdle rate”) that LPs must earn before the GP takes any carry.
Your management fee funds day-to-day operations: salaries, rent, research, travel. Carried interest is your performance incentive and typically only pays out after the fund returns investor capital plus the preferred return. Many LPAs include a “clawback” provision requiring the GP to return excess carry if later investments underperform and the overall fund doesn’t meet its return threshold.
Raise Capital and Close the Fund
With your legal documents, exemption filing, and service providers in place, you can begin accepting investor commitments. Most private funds raise capital over a defined fundraising period, often 12 to 18 months, with an initial close when you’ve hit a minimum viable fund size and one or more subsequent closes as additional investors come in.
For a first fund, your initial investors will almost certainly come from your personal and professional network. Institutional investors like pension funds and endowments rarely commit to a manager without a multi-year track record. Building a compelling track record from prior personal investments, a separately managed account, or a smaller fund is the most reliable path to attracting institutional capital for a second or third fund.
Each investor signs the subscription agreement, makes representations about their accredited status, and commits a specific dollar amount. Capital is typically not wired upfront. Instead, the GP issues “capital calls” as investment opportunities arise, drawing down a percentage of each LP’s commitment as needed. This structure means you need a clear capital call process and a responsive administrator from day one.
