Leaving a Multi-Manager Platform to Launch Your Own Hedge Fund: The Portfolio Manager's Launch Sequence

To launch your own hedge fund after leaving a multi-manager platform, a portfolio manager has to do three things the platform previously did for them: build or source the operating infrastructure around the strategy, establish a fund and a manager entity that investors will accept, and raise outside capital against a track record that was earned inside someone else's fund. The notice period and any garden leave are the launch window: formation, service provider onboarding and account opening can commonly be prepared during it, subject to the individual's contract, while approaches to restricted investors and colleagues wait. The investment edge travels with the manager. Almost everything around it has to be rebuilt.

A portfolio manager leaving a multi-manager platform has spent years with risk, financing, execution and compliance handled by someone else. The strategy is ready on the first day. The fund around it is not. The managers who launch well treat the notice period as a build period, decide early which parts of the platform they need to replicate, and accept that their first fund will be smaller than the book they ran. That is a starting point, not a setback.

Executive Summary

A book on a multi-manager platform and an independent hedge fund are different businesses. The first is a risk-taking role inside an operating structure; the second is the operating structure. The launch sequence is about closing that gap in the right order.

• The platform's central functions, risk oversight, financing, execution, compliance and reporting, become the new manager's responsibility, either built in-house or sourced through a fund platform and service providers.
• The notice period and garden leave are the build window; what may be done during them is set by the individual's employment contract, not by market convention.
• The performance of a book run inside another firm's fund is not freely portable. For an SEC-registered adviser, the Marketing Rule sets specific conditions for presenting predecessor and extracted performance.
• Launch AUM is commonly a fraction of the capital the manager deployed on the platform, so position sizing, financing terms and the manager's own break-even need to be recalibrated.
• The structural choice between a segregated portfolio on a platform and a standalone fund, and the location and licensing of the manager entity, should be made before the capital raise starts.

What the Platform Provided That the New Manager Must Replace

On a multi-manager platform, a portfolio manager is commonly allocated capital, given risk limits by a central function, financed through the platform's prime brokerage relationships, and supported by central execution, technology, compliance and operations. Payout is linked to the book's results. The manager's job is to generate risk-adjusted returns within that framework.

An independent fund reverses the arrangement. The manager is now responsible for the framework, and every function the platform supplied has to be answered for, to investors, to the fund's board and to the service providers that will onboard the fund.

The question for each row is not whether to replicate the platform but what level of control the strategy actually needs at launch size, and whether that control is built in-house, delegated to service providers or provided by a fund platform.

The Notice Period and Garden Leave as the Launch Window

Portfolio managers at large platforms commonly have notice periods, garden leave provisions and post-termination restrictions on competing, soliciting investors and soliciting colleagues. Their content and length vary by firm, by seniority and by jurisdiction, and they are matters of the individual's own employment contract. The first task, before resignation, is to read that contract closely and establish the earliest date on which the manager can trade, the date from which investors can be approached and which investors and colleagues are covered.

Within those limits, the restricted period is the most productive time in the launch. Much of the work that delays a fund launch does not involve trading or marketing.

Two disciplines matter throughout. Nothing belonging to the former employer, including code, models, position data and investor information, should be taken or used. And any approach to a covered investor or colleague, directly or through an intermediary, should wait until the relevant restriction has ended. Our analysis of non-competes, garden leave and lift-outs sets out what a departing team can and cannot take and how restricted periods shape launch timing.

Track Record: What a Former Platform PM Can Present

The returns a manager generated on a platform are the manager's professional history, but the records behind them belong to the former employer, and the book was a subset of a larger fund. That creates three practical constraints.

First, evidence. A return series without underlying records is a claim, not a track record. Allocators will ask how the numbers were produced and who can confirm them, and the supporting records sit with the former firm.

Second, regulation. For an investment adviser registered or required to be registered with the SEC, Rule 206(4)-1 under the Investment Advisers Act permits predecessor performance in an advertisement only if four conditions are met: the people primarily responsible for the prior results manage accounts at the new adviser; the prior accounts are sufficiently similar to those now managed; all substantially similar accounts are included, unless excluding any would not result in materially higher performance; and the advertisement clearly and prominently discloses that the results were achieved at another entity. The rule separately treats extracted performance, meaning the results of a subset of investments taken from a portfolio, and requires that the total portfolio's results be provided or offered promptly. A book inside a multi-manager fund may engage both provisions, and the analysis depends on the facts.

The same rule requires gross performance to be accompanied by net performance, and Rule 204-2(a)(16) requires the adviser to keep the records necessary to demonstrate the calculation of any performance it advertises. A manager who cannot obtain those records should not expect to present the figures in regulated marketing. Our guide to the SEC Marketing Rule for offshore fund managers explains which advisers the rule covers; exempt reporting advisers are outside it, but the general anti-fraud provisions of section 206 of the Act apply to any investment adviser.

Third, relevance. Even a fully documented book record reflects platform conditions: central risk limits, platform financing and a capital allocation the manager did not raise. Allocators assessing the record will want to understand how the strategy will run without them. The most persuasive answer is a verifiable live record from the new fund's first month, produced by an independent administrator.

Risk, Financing and Execution Without the Platform

The functions a platform PM is least likely to have run directly are the ones investors in a new fund will examine closely.

Risk. On a platform, the manager's drawdown limits and exposure limits are imposed from outside the book. In an independent fund, the manager writes them. Investors and the board will expect a documented framework, covering gross and net exposure, concentration, liquidity and drawdown triggers, with someone other than the person taking the risk monitoring it. A former platform PM is well placed to design this, having worked within one; the discipline is to keep it as firm when it is self-imposed.

Financing. A platform negotiates financing on the strength of its combined assets and relationships. A new fund is a new client. Margin rates, haircuts, borrow availability and the terms on which a prime broker can change them are negotiated afresh, and at launch size they are often less generous than the PM is used to. Strategies that depend on leverage or on hard-to-borrow shorts need this resolved before launch, not during it. Our guide to choosing a first prime broker as an emerging manager covers what to test.

Execution. Broker panels, algorithms and market access that came with the platform have to be re-established, with a best execution policy and a process for reviewing it.

Compliance. The new manager entity needs its own compliance programme: personal account dealing, inside information controls, trade allocation and record keeping, scaled to the entity's licensing and the strategy's markets.

Capacity and Economics: Launching Smaller Than the Book You Ran

The capital a PM deployed on a platform was the platform's allocation. The new fund's capital is whatever investors commit, and it is commonly a fraction of the book. That has consequences for the strategy and for the business.

For the strategy, position sizing, turnover and the number of names need to work at launch AUM and with the financing actually available. A strategy calibrated to a large allocation with platform leverage may need a different gross exposure, and that should be reflected in the offering document's risk disclosures.

For the business, the economics change from a payout on results to a management company that must cover its own costs. Platform pass-through models commonly charge costs to investors in a way a new fund cannot replicate. The independent manager lives on its management fee until performance fees arrive, and performance fees are uncertain. Our analysis of break-even mathematics for emerging hedge funds sets out how fixed costs, fee rates and runway determine the AUM a manager needs.

Fee terms with first investors are part of the same calculation. Discounts that win early capital also lower revenue at the point it matters most, so the size, duration and capacity limits of any discount should be modelled before they are offered.

First Investors

A departing PM's first investors commonly come from four sources: the manager's own capital and that of partners; individuals who know the manager's work, which can include former colleagues, subject to any non-solicitation restriction; allocators who have followed the PM's career and are prepared to back an emerging manager; and seed investors, who provide larger commitments in exchange for a share of the management company's revenue or other economics.

Founder share classes are the common tool for rewarding early investors without a revenue share, through reduced fees for a defined period or up to a capacity limit. Our guide to founder share classes for hedge funds covers duration, conflicts and operational handling. A seed arrangement is a different transaction, a sale of part of the business, and should be assessed as one.

Choosing the Structure and the Manager Entity

Two decisions shape everything else. The first is the fund vehicle. A segregated portfolio on an established platform gives the manager a fund with an existing board, administration, audit and regulatory framework already operating; a standalone fund gives full control of the vehicle and its service providers, at the cost of building and maintaining them. For a manager who has just left a platform, the comparison often turns on time to launch and fixed cost at launch AUM.

The second is the manager entity: where the investment management business is incorporated and where its people sit. That determines its licensing. In the United States, an adviser must register with the SEC under the Advisers Act unless an exemption applies; Rule 203(m)-1 exempts an adviser with its principal office in the United States that acts solely for qualifying private funds and manages private fund assets of less than $150 million. In the United Kingdom, section 19 of the Financial Services and Markets Act 2000 prohibits carrying on a regulated activity unless the person is authorised or exempt. Licensing applications have their own lead times and are commonly started during the restricted period.

The Launch Sequence from Resignation to First Trade

1. Before resigning, read the employment contract to establish the notice period, garden leave, non-compete and non-solicitation terms, and the earliest dates for trading and for approaching investors.
2. Decide the target strategy at launch scale: gross and net exposure, financing needs, markets and liquidity.
3. Choose the fund vehicle and the manager entity's location, and begin any licensing or registration process.
4. Agree fund terms: dealing frequency, notice periods, lock-ups, fees and any founder share class.
5. Onboard the administrator, auditor, prime broker and bank, and negotiate financing terms for the new fund.
6. Document the risk framework, compliance programme and best execution policy.
7. Prepare investor materials, with any performance presentation reviewed against the rules that apply to the manager.
8. Once restrictions end, approach investors, accept subscriptions and fix the first dealing day.
9. Fund accounts, begin trading and reconcile the first positions with the administrator.

The First 100 Days

For a former platform PM, the first months after launch test whether the replacement infrastructure works. The first NAV strike, the first investor report and the first board meeting are where gaps appear: a reconciliation that the platform's middle office would have caught, a risk limit nobody else is monitoring, a financing term that tightens after a volatile week. Our guide to a fund manager's first 100 days after launch sets out the operating checklist; the point for a departing PM is that each of those milestones also builds the verifiable record the platform book could not provide.

Common Mistakes

• Resigning before reading the employment contract and establishing the restricted periods and covered investors.
• Assuming platform financing terms will be available to a new fund at launch size.
• Presenting a platform book's returns without the supporting records, or without checking the marketing rules that apply.
• Calibrating the strategy to the old allocation rather than to realistic launch AUM.
• Leaving fund formation and service provider onboarding until the restricted period has ended.
• Offering founder discounts without modelling their effect on the manager's break-even.

The CV5 Implementation Perspective

CV5 Capital is the Cayman-headquartered institutional fund infrastructure platform for hedge fund and digital asset managers who need to launch quickly, operate properly and satisfy serious investors from day one. It operates CV5 SPC for traditional strategies and CV5 Digital SPC for digital asset strategies, both registered with CIMA under the Mutual Funds Act. Each manager receives a segregated portfolio with an independent board and coordinated fund administration, audit, banking, custody and compliance arrangements. CV5 Capital is not the investment manager of the strategies on its platforms.

For a portfolio manager leaving a multi-manager platform, a Cayman hedge fund platform for independent managers replaces part of what the old platform provided at the fund level: governance, administration, audit and coordinated service provider arrangements. The manager remains responsible for the strategy, its risk limits and its investment decisions, and can use the restricted period to complete the fund-level work so that the launch follows soon after restrictions end.

Key Takeaways

• Read the employment contract before resigning and fix the earliest trading date and the earliest date for approaching investors.
• Use the restricted period for formation, licensing, onboarding and documentation, and take nothing belonging to the former employer.
• Treat the platform book's returns as history that needs evidence, and check the presentation against the marketing rules that apply.
• Replace central risk, financing, execution and compliance deliberately, and document each before launch.
• Recalibrate the strategy and the business to realistic launch AUM and model fee concessions against break-even.
• Decide the fund vehicle and the manager entity before the capital raise begins.

Frequently Asked Questions

Can a portfolio manager set up a fund during garden leave?

Often, yes, but the answer depends on the individual's employment contract. Fund formation, licensing applications, service provider selection and account onboarding do not involve trading or approaching investors, and are commonly prepared during the restricted period. Trading, and approaching investors or colleagues covered by a non-solicitation restriction, commonly wait until the relevant restriction ends. The contract should be read before resignation.

Can a former multi-manager PM use their platform track record?

The returns are part of the manager's professional history, but the supporting records belong to the former firm and the book was part of a larger fund. For an SEC-registered adviser, predecessor performance may be advertised only if specific conditions are met, including similarity of accounts and clear disclosure that the results were achieved at another entity, and the adviser must keep records supporting the calculation.

Why is launch AUM often smaller than the book the PM ran?

Capital on a multi-manager platform is allocated by the platform from its own investor base and can be withdrawn at its discretion. An independent fund starts with the capital its own investors commit, which is commonly a fraction of the previous allocation. The strategy, financing and the manager's cost base therefore need to be calibrated to realistic launch AUM.

What does a new fund need to replace from the platform?

The central functions: risk limits and their monitoring, financing and leverage arrangements with prime brokers, execution and broker relationships, compliance controls, and operations including reconciliation and reporting. Some are built within the manager entity, some are provided by service providers such as the administrator and prime broker, and fund-level governance and administration can be provided by a fund platform.

Should a departing PM use a fund platform or a standalone fund?

A segregated portfolio on a platform provides an existing board, administration, audit and regulatory framework, which shortens the build and lowers fixed cost at launch AUM. A standalone fund offers full control of the vehicle and its service providers at greater cost and time. The choice depends on launch AUM, investor expectations and how much infrastructure the manager wants to own.

Does the manager entity need to be licensed?

The answer depends on where the manager entity and its people are located. In the United States, an adviser must register with the SEC unless an exemption applies, such as the private fund adviser exemption for advisers that act solely for qualifying private funds with less than $150 million in private fund assets. In the United Kingdom, regulated activities require authorisation or an exemption. Other jurisdictions apply their own regimes.
