The Custodian-Minimum Myth That Distorts RIA Startup Budgeting

The Myth That Stops People Before They Start

'I don't have enough AUM to get a custodian' is one of the most common reasons prospective independent advisors give for staying at a wirehouse or broker-dealer longer than they want to. It's worth separating from every other, legitimate reason to wait — this specific belief is, for the major retail-RIA custodial platforms, simply not accurate. Treating it as a real constraint means budgeting time and capital around a barrier that doesn't exist at the platforms most solo and small RIAs actually use, while under-budgeting for the costs that are real: compliance setup, insurance, and software. It also delays a decision that has a real cost of its own — every additional year spent waiting for a book that feels 'big enough' is a year of income and equity building at someone else's firm instead of your own.

What the Custodians Themselves Actually Say

Altruist states on its own site that there are no AUM minimums. Betterment Advisor Solutions states the same thing in its own words — no minimum AUM requirement. Axos describes itself as welcoming opportunities to work with RIA firms of all sizes. Beyond those explicit statements, Schwab, Fidelity, Pershing, Raymond James, Interactive Brokers, Apex, RBC, and Goldman all publish no firm minimum for working with a new RIA either. This is a case where checking the primary source — the custodian's own published language — settles a question that a lot of secondhand commentary gets wrong. Before you take any secondhand claim about a custodian's requirements at face value, including anything in this guide, pull up that custodian's own RIA-onboarding page and read the actual language yourself — it takes a few minutes and removes any doubt.

Where the $2M–$5M Number Actually Comes From

The figures most often cited as a Schwab minimum — $2 million, rising to $5 million — are real numbers, but they describe something different from custody: they're the per-client asset floors for the Schwab Advisor Network, a separate referral program that connects Schwab's own retail clients to independent RIAs. Confusing that referral-program floor with a custody minimum is, by a wide margin, the single most common error people make researching this question, and it's worth checking any source that states a Schwab AUM minimum against this distinction directly rather than repeating it. If you're evaluating Schwab for custody and separately wondering whether the referral network is worth applying to once you're established, keep the two programs mentally separate — you can use one without the other, and neither is a prerequisite for the other.

One Small Correction Worth Knowing: Fidelity's Platform Has a New Name

If your research turns up references to 'WealthCentral' as Fidelity's custodial platform for RIAs, that name is retired — the current platform is Wealthscape, and Fidelity's own 'Start an RIA' materials confirm no AUM minimum applies there either. This matters less for the substance and more as a signal: if a source you're reading uses the old name, treat everything else in it as potentially dated too, and verify the current details directly against the custodian's own site rather than the secondary source. Platform names and program details in this industry change more often than founders researching it for the first time expect, which is exactly why primary sources are worth the extra few minutes over a blog post or forum thread that may be a few years stale.

Scale Cuts Both Ways: What Schwab's Own Numbers Show

Schwab's own published figures put roughly 15,000 RIAs on its platform, custodying over $5.5 trillion in client assets. That scale is proof there's no artificial capital gate keeping small firms out — a platform serving that many RIAs isn't screening for size at the door. It's also a reminder that differentiation still matters: a crowded platform means your actual edge has to come from your niche, your service model, and your fee structure, not from having cleared some imagined minimum that, per the custodian's own statements, was never a real barrier. If you're weighing a single large custodian against a newer platform like Altruist specifically because you're worried about being too small to matter to either one, that worry is misplaced either way — neither publishes a size gate, and both actively court small and newly formed RIAs as a growth strategy of their own.

So What Should You Actually Budget For?

If custody access isn't the capital constraint, redirect that budgeting attention to what actually costs money at launch: compliance setup (whether DIY, a consultant, or a securities attorney), your E&O policy, portfolio management and financial planning software, and CRM — all covered in more cost detail in our startup-costs guide. Get your bookkeeping running from day one so you can see these costs clearly as they hit, and keep your business bank account separate from personal funds so there's no ambiguity about what the business actually spent to get to its first client. Your state's net-worth and bonding requirements — a genuinely real capital question, unlike the custodian myth — are covered in our Location guide, since the specific figures depend on which state you designate as your principal office.
