Common Sticking Points and How Firms Work Through Them in Practice
Closed-end drawdown funds, as white-labeled “custom funds,” are not new. They’ve been part of institutional private market investing for decades, and many RIAs already use them today.
What continues to make them strategic is not novelty. It is leverage.
Private markets have evolved well beyond niche allocations. In 2025, roughly 80% of advisors across channels now include alternatives in accredited client portfolios. Nearly as many expect to increase those allocations this year as private equity, private credit, and other illiquid strategies become core components of diversified wealth portfolios.
“Custom funds” give RIAs a way to bring structure, consistency, and scale to private market investing. Instead of scrambling every time a new opportunity appears, firms can create a repeatable vehicle that aligns with their investment philosophy. This simplifies the client experience and strengthens their position with managers. For some firms, the appeal is negotiating leverage and operational efficiency. For others, it is differentiation and the ability to deliver a more institutional experience to clients. Often, it is all of the above.
I’m Charles Patton, Director of Investments at Gridline. I spend my days talking with RIAs and General Partners and working directly with firms that are launching, running, or refining custom fund strategies. What follows are lessons that surface repeatedly across RIAs of different sizes and stages of growth, but that share an interest in firm differentiation and alpha generation for their clients. Whether you’re an RIA launching your first custom fund or have done so before and are looking to do it better, my hope is that these lessons prove a valuable resource as you further your private market strategy.
Gotcha 1: “We’ll just stitch this together ourselves.”
This is often the first moment when enthusiasm meets operational reality.
At a high level, a custom fund feels manageable: form a vehicle, elect managers, raise capital, let it ride.
What this looks like in practice
- Legal formation sits with one provider.
- Fund administration with another.
- Subscriptions handled somewhere else.
- Performance reporting tracked separately.
- Client documents stored in yet another place.
None of these pieces are inherently problematic on their own. The challenge emerges when the fund moves from setup to live operation and capital starts moving.
Why this trips firms up
The work extends beyond finding vendors. It is managing the handoffs between them. Reconciling data across systems. Making sure subscription information matches capital calls. Catching inconsistencies before clients notice. Over time, the RIA often becomes the integrator, carrying much of the coordination and oversight responsibility. This is true for firms launching their first custom fund and for firms that have done this before but are now trying to scale.
What changes when this is handled well
Firms that move through this successfully tend to reach the same conclusion: fragmentation is the risk. Consolidation is the release valve. When firms design the operating model so the heavy lifting lives in one place, advisors can spend time on portfolio decisions and client conversations rather than coordination.
Gotcha 2: “Putting our name on this elevates the risk.”
Some RIAs perceive that launching a custom fund elevates the brand reputation risk for their firm and individual advisors because the vehicle carries their name and is built specifically for their clients. Yet this is usually precisely why they’re often drawn to the strategy in the first place: market differentiation and well-thought-through asset class allocation.
What this looks like in practice
While allocating to the most well-known interval funds can feel like a problem solved, this can kick the can down the road should returns remain pedestrian or promised liquidity fail to materialize. When advisors answer their key questions on privates early and align on how their firm is differentiated, the dynamic shifts. What feels like a liability becomes a source of competitive edge.
Why this trips firms up
What’s sometimes less visible is that RIAs are already accountable for private market outcomes through manager selection, portfolio construction, and client guidance, regardless of whether their name is on the fund. The difference with a custom fund is the RIA isn’t beholden to the rigidity of an off-the-shelf third party fund when creating a bespoke bundle of funds or FoF (fund of funds) that’s been structured based on the investment thesis and risk tolerance profile the RIA is comfortable with.
What changes when this is handled well
When firms are clear about how the vehicle will operate and how expectations will be set over time, the focus tends to shift from perceived exposure to intentional ownership of the structure.
Gotcha 3: “Clients are going to be confused, and we’ll spend all our time overcoming objections.”
Most advisors can point to a moment when a client reacted negatively to something unfamiliar. Perhaps it was a capital call, an account value that didn’t move, or a statement that looked nothing like a brokerage report.
What this looks like in practice
During the launch quarter, client questions spike. Advisors find themselves explaining capital calls, why committed capital has not yet been fully deployed, and why early account values or statements do not look like public market reporting.
Why this trips firms up
The fear is not that clients will dislike private markets. It is that the mechanics will overshadow the strategy, especially early on.
What changes when this is handled well
In practice, much of the confusion centers on pacing and expectations. Firms that anticipate this use models to show how capital calls and distributions typically unfold and explain what clients will see before they see it. Once that initial work is done, the model becomes simpler to run and significantly more scalable over time.
Gotcha 4: “We don’t have the team for this.”
Custom funds often feel like something only very large firms can support.
What this looks like in practice
Firms assume launching a custom fund requires significant new headcount to manage subscriptions, documentation, and ongoing administration. The effort starts to feel out of reach, even when investment conviction and client interest are there.
Why this trips firms up
This often brings staffing to the foreground of the decision. In reality, the work is real, but it is concentrated. Most of the effort shows up during the launch quarter, when clients are onboarded, documents are collected, and questions are answered.
What changes when this is handled well
Across firms of all sizes, the gating factor is rarely headcount. It’s clarity. Who owns the process, where documents live, and how information flows once capital starts moving. When those pieces are defined, and the initial work is absorbed, the model becomes far more scalable than managing private investments fund by fund. In practice, firms that navigate this well pair clear internal ownership with an infrastructure partner that absorbs much of the operational lift.
Gotcha 5: “All the good managers are locked up.”
This concern comes up frequently, even among firms that have allocated to private markets for years. That concern isn’t entirely misplaced; some established managers are fully spoken for and may remain that way for some time.
What this looks like in practice
Discussions tend to center on a short list of well-known managers. If access to those names feels limited or unavailable, it can create the impression that the broader opportunity set is closed.
Why this trips firms up
This can make private markets feel like a fixed universe. In reality, some established managers are fully spoken for, but the market itself is constantly changing. Fund sizes grow. Teams evolve. New managers emerge. The dynamics that made a firm exceptional at one scale do not always persist at another.
What changes when this is handled well
Rather than anchoring on a static list of names, firms focus on understanding how manager quality evolves over time and where the next generation of strong managers is emerging. For RIAs in the wealth channel, this creates an opportunity to access strategies and talent that are still early, rather than competing for capacity that may already be fully allocated.
How Firms De-Risk the Move as a Whole
Across successful custom fund strategies, a few patterns show up consistently. These are not theoretical best practices. They reflect what I’ve seen work first-hand across firms of different sizes and levels of experience.
1. They model pacing before committing to structure.
Firms model capital calls and distributions in advance, so they understand how cash will move over time and what that means for client portfolio planning.
2. They shape the portfolio with real client input early.
Rather than launching cold, firms have early conversations with a small group of clients to understand preferences, pressure test assumptions, and build alignment before commitments are requested.
3. They align internally before fundraising begins.
Investment leadership takes time to align on philosophy and conviction, so the rationale carries through client conversations, fundraising, and the inevitable questions that surface early on.
4. They treat the launch quarter as front-loaded work, not ongoing friction.
Firms plan for a concentrated period of effort around onboarding, documentation, and education, secure in the knowledge that they are building a more scalable system.
Infrastructure is What Makes All of This Viable at Scale
In practice, many of the perceived risks around custom funds, staffing burden, client confusion, and operational drag come from private investments being bolted onto workflows that were never built to support them. Firms that de-risk the move treat infrastructure as foundational, not ancillary. Onboarding, subscriptions, document management, capital calls, reporting, and performance visibility live in systems designed for private assets, often supported by a dedicated partner that absorbs much of the operational lift.
When that foundation is in place, the complexity of private markets doesn’t disappear; it becomes contained. Responsibilities are clear, effort is front-loaded, and the strategy scales intact rather than becoming more fragile as assets grow.
Closing
Custom funds carry real complexity. In practice, outcomes tend to hinge on whether that complexity is addressed deliberately and supported by the right operating model.
When firms approach these structures with clarity and intention, closed-end drawdown funds become a powerful way to deliver differentiated exposure, strengthen alternatives programs, and offer clients an experience that feels institutional rather than improvised.
Across customers Gridline has partnered with, they’ve noticed increased client buy-in, a higher barrier to exit given the long-lived nature of the funds, and excitement from forward-thinking advisors with a greater variety of tools to use to improve client outcomes.
That is what it looks like to set a new standard in private market investing.
