Aggregators and therapist independence:

Every therapist who’s joined Alma or Headway had a reason. Credentialing is slow and opaque. Insurance billing is a time sink. Starting a caseload from zero is hard. These aggregators stepped into genuine pain points, and for many therapists they delivered. That’s worth saying plainly before anything else because this piece isn’t an argument against aggregators. We want to help you understand how they work, so you can decide whether it’s still a good fit.

But aggregators are also businesses with their own economics, and the structure of those economics affects your practice in ways that aren’t always obvious when you’re signing up and that compound over time in ways that can impact your practice.

The appeal is real, but so is the cost

Aggregators typically handle insurance credentialing, payer contracting, and billing in exchange for a percentage of your reimbursement on every session. For a therapist starting out, that tradeoff often makes sense. Credentialing alone can take 90 to 120 days and requires navigating payer-specific processes that vary significantly. Outsourcing credentialing is a reasonable decision if it helps you get into practice faster.

The issue is that the tradeoff doesn’t change as your circumstances evolve. The aggregator takes the same cut whether you’re building your first caseload or running a full schedule you’ve maintained for three years.

We’ve already written about why we think it’s worth it to get credentialed on your own. At the same time, we’ve written a few credentialing guides, so we see just how much work goes into it, and why a therapist may not have the time to do it.

And let’s not forget the elephant in the room: reimbursement rates. Many therapists partner with these services not because they can’t handle getting credentialed, but because these aggregators often negotiate higher reimbursement rates from insurance companies. That would be difficult for a practice to negotiate without collective action.

How the revenue math works

Most aggregators retain a percentage of your reimbursement per session (some charge a flat monthly fee rather than a percentage), in exchange for handling credentialing, billing, and client referrals. It becomes an ongoing operational expense.

On a full caseload, that adds up to a meaningful annual sum that, at a certain point, exceeds what you’d pay to run your own billing and credentialing infrastructure.

The exact crossover varies depending on your session rate, payer mix, and how much administrative work you’re willing to take on. But the principle holds: aggregators front-load the value and back-load the cost. When you most need the help, the fee feels small. As your practice matures and the help you needed most is no longer what you need, you’re still paying for it.

The point at which independent infrastructure costs less than the aggregator percentage arrives well before a full caseload for most therapists.

It’s also worth noting that the negotiated rates may start much higher than what you could negotiate on your own, but they may not stay that way. Reporting from ClearHealthCosts in late 2024 documented Alma and Headway notifying clinicians of pay cuts on Optum codes, with some therapists reporting reductions of $30 or more per session and projected annual income losses ranging from $6,000 to $28,000.

While the fees may seem small and the reimbursement rates high, you should do some digging. A 2025 study from the Psychotherapy Action Network surveying 667 therapists found that half of clinicians using these aggregators reported earning the same or less than they would in independent practice, and 84% said they were not informed about fee-splitting arrangements before joining.

The inflection point

For most therapists, the financial case for independence starts to emerge somewhere around a consistently full or near-full caseload. At that point, the aggregator is no longer solving a capacity problem, it’s processing sessions you would have had anyway, and charging for the privilege. Whether that inflection point is worth acting on depends on factors specific to your practice, but knowing it exists is the starting point.

What you’re trading beyond money

Revenue share is visible and quantifiable. The less-discussed costs are harder to measure but worth taking seriously.

Client relationships

On most aggregators, the clients you see are technically the aggregator’s clients, not yours. If you leave, your ability to continue seeing those clients or even to notify them, may be constrained by the aggregator’s terms. Policies vary and do change, so your specific contract is what matters. This is a question worth getting a clear answer to before you’re in a position where it matters.

Aggregator dependency

Your practice’s administrative infrastructure, referral flow, and billing processes are built on someone else’s system. When that system changes its terms, adjusts its reimbursement structure, or makes decisions about which specialties or geographies to prioritize, your practice absorbs those changes whether or not they suit you.

Many aggregators also require you to use their telehealth software or EHR, and set their own documentation and productivity standards. That’s not unique to aggregators, but if you left a group practice for more autonomy, these constraints can feel like the same trap in a different form.

Practice identity

Clients often find you through the aggregator’s marketplace, which means your visibility and client acquisition are tied to how the aggregator presents you: its algorithm, its filters, its brand. When the aggregator’s reputation takes a hit, yours does too. Building a recognizable independent practice presence takes longer but creates something you own.

They’re part of the problem

ClearHealthCosts’ 2025 reporting documents that Alma has investment from Cigna Ventures and Optum Ventures, Headway has investment from Health Care Service Corporation (the largest customer-owned Blue Cross Blue Shield licensee), and Rula has investment from the Blue Venture Fund. While that means they often have good relationships to get you better rates, it also means they benefit directly from keeping the system broken.

A self-assessment framework: Five questions

These questions are designed to be run against your actual situation, not idealized ones.

1. Is your caseload consistently full? If you regularly turn away clients or maintain a waitlist, the aggregator’s client acquisition function is no longer serving you. You’re paying for it anyway.
2. Do you know what you’d pay for independent billing and credentialing? Most therapists haven’t priced this out. The number is often lower than assumed, especially with the automated billing available in some EHRs and revenue cycle management (RCM) services incentivized to help you bring in revenue.
3. Have you read the client transition terms in your contract? Not a general summary, the actual language. This is the highest-stakes detail for long-term practice continuity.
4. Are your clinical decisions or scheduling affected by aggregator requirements? Some aggregators have session minimums, documentation requirements, or payer constraints that shape how you practice. If you’re working around those, that’s a real cost.
5. What would it take to be off this aggregator in 18 months? If you can’t answer that question, you don’t have an exit, you have a dependency. That’s not necessarily wrong, but it should be a conscious choice.

Vetting an aggregator? Here’s the question list we’d start with.

When staying on an aggregator is the right call

There are circumstances where the aggregator model is genuinely the right fit, and it’s worth being direct about them.

If you’re in the first one to two years of practice, the credentialing support and built-in referral pipeline may be worth the cost, not as a permanent structure, but as scaffolding while you build a caseload and learn the business side of practice.

If you have a high tolerance for clinical work and a low tolerance for marketing or administrative complexity, outsourcing that layer may be worth the ongoing percentage. If you’re in a market where the aggregator’s payer contracts give you access you couldn’t replicate independently, that access has real value.

And if the aggregator’s negotiated reimbursement rates are materially higher than what you could secure on your own, the math may favor staying, especially in markets where solo practitioners have little leverage to negotiate with payers and no realistic path to collective bargaining. A larger cut of a larger number can still beat a full cut of a smaller one.

The therapists who benefit most from aggregators tend to be early-career, in high-demand markets, or genuinely uninterested in the operational side of running a practice. Like much of our technology nowadays, they bank on you choosing ease and convenience.

What does building towards independent look like?

Independent practice infrastructure means holding your own payer contracts, running your own billing, and owning your client relationships outright.

In practice, that usually involves three things: an EHR that handles documentation, billing, and scheduling, a billing process (in-house or through an RCM service) that manages claims and follow-up, and direct credentialing with the payers your clients use. Tools like TheraNest pair EHR functionality with revenue cycle management services specifically built for mental health practices, which means therapists can replicate what an aggregator does administratively without the per-session fee and without ceding control over how the practice operates.

This infrastructure requires setup time and some upfront decision-making. It’s not passive. But once it’s in place, it scales with your practice instead of extracting from it.

Ask yourself

If you built your practice from scratch today, knowing what you know now, would you choose the same structure you’re in?

For some therapists the answer is yes, the tradeoff still holds. For others, the honest answer is that the setup made sense at a particular moment and that moment has passed. Neither answer is wrong. The goal isn’t to convince you one way or the other. It’s to make sure the structure you’re in is one you’d still choose, not just one you’ve stayed in.
