Athena vs. Prialto vs. Double vs. Outsourced Scale: Which EA Service Is Right for You?

The four services in this comparison take fundamentally different approaches to EA support. Pricing, commitment terms, and who each service is built for vary enough that a wrong fit costs real money, not just subscription fees, but onboarding time, workflow disruption, and the management overhead of switching. One page that does the comparison work honestly is more useful than four vendor websites that each make the same case for themselves.

This article covers the same four criteria for each provider: who the service is specifically built for, how pricing and commitment terms work, what onboarding looks like in practice, and where the service breaks down for buyers outside its intended fit. If you are still building your shortlist, the best executive assistant outsourcing companies overview covers the broader category before this level of comparison.

Why this comparison matters, and what to look for before you pick

Comparison shopping for an EA service is not the same as comparing software subscriptions. You are evaluating an ongoing relationship with real onboarding costs, commitment terms, and replacement risk. Getting to the right answer requires looking past marketing language at the actual structure of each service.

The four things that actually separate EA services

Every provider in this comparison will tell you they deliver consistent, high-quality executive support. What actually separates them is more specific. The evaluation criteria this article uses for each provider are:

• ICP fit. Who the service is specifically designed for, and whether your firm type matches that profile.
• Pricing model and commitment terms. What you pay, how billing works, and what it costs to exit if the fit does not hold.
• Onboarding structure. What the first 30 to 60 days look like in practice and what you are responsible for versus what the provider handles.
• Where the service breaks down. The buyer types and situations where each service is a poor fit, stated plainly.

A note on pricing transparency in this category

Several providers in this space do not publish full pricing publicly. Where confirmed pricing is available from first-party sources, it is cited here. Where pricing requires a sales call to confirm, that is noted. No pricing figures in this article are estimated or fabricated.

Athena, built for full-time executive partnerships at a premium price

Athena is the highest-cost service in this comparison and the most structured. At $3,000 per month on a 12-month commitment, it is built for founders and executives who want a full-time dedicated Executive Partner, not a fractional or task-based arrangement.

Who Athena is actually built for

Athena’s intended buyer is a high-volume founder or executive who needs full-time, deeply embedded support and who may have struggled to delegate effectively in the past. Their model pairs each client with a Philippines-based Executive Partner working US business hours, plus an executive coach who helps the client delegate better.

That coaching layer is a genuine differentiator. Athena trains both the EA and the client. For a buyer who has hired support before and found themselves micromanaging or struggling to hand off work, that structured delegation training has real value. It is less relevant for an operator who already has documented workflows and needs steady execution rather than coaching on how to build them.

Athena pricing and commitment structure

Confirmed pricing: $3,000 per month on a 12-month commitment, totaling $36,000 per year. A $24,000 buyout fee applies if the client wants to hire their Executive Partner directly. There is no fractional or part-time option; Athena is full-time only.

This pricing sits at roughly two to three times the cost of comparable offshore managed services. That premium is justified by the coaching infrastructure and the managed performance model. For a founder who has not successfully delegated before, the overhead may pay back. For an operator who already runs documented workflows, it likely does not.

Where Athena breaks down

Athena is not built for small firms on tight margins, for firms that need fractional coverage, or for buyers who already have strong delegation habits and do not need the coaching layer. The 12-month lock-in with a $24,000 buyout fee is a real risk for a sub-15-person firm if the match does not work. Athena also does not specialize in industry-specific workflows. A CPA firm owner who needs an EA trained in SmartVault, TaxDome, or the specific rhythms of tax season will find a generalist executive support model requires additional workflow training on their end.

Prialto, managed team infrastructure for executives who need redundancy

Prialto‘s model is structurally different from the others in this comparison. Rather than matching one EA to one client, Prialto assigns a primary assistant, a backup assistant, and an engagement manager. The redundancy is the product. You are buying coverage continuity, not a dedicated individual relationship.

Who Prialto is actually built for

Prialto targets individual executives, teams, and enterprise organizations. As of 2025, Prialto is the only SOC-2 Type 2-compliant managed VA service, which matters for buyers in regulated industries or enterprise security environments.

The engagement manager model means the buyer is insulated from individual EA turnover. If your primary assistant leaves, the backup and engagement manager maintain continuity and context. This is the right model for buyers who have been burned by single-point-of-failure arrangements before, or for organizations where information security compliance is a procurement requirement.

Prialto pricing and commitment structure

According to Prialto’s published FAQ, one unit of support covers approximately 55 hours per month and costs $1,500, which works out to $27 per hour with all management overhead included. Full-time equivalent coverage requires three units at $3,600 per month. A $250 setup fee applies, waived on a one-year commitment. The minimum contract is 90 days.

Prialto’s billing model requires the buyer to track unit allocation. You are managing hours consumed, not just outcomes. For a buyer comfortable with that level of tracking, the model is clear. For a founder-operator who wants to hand off work and not think about hour consumption, the unit-based structure adds a layer of overhead.

Where Prialto breaks down

Prialto’s team model means you are not always working with the same person. For executives who need high-context, relationship-dependent support, such as someone who remembers communication preferences, relationship history, and tone for specific contacts, the team handoff model creates friction that a dedicated individual does not.

The unit-based billing also adds cognitive overhead. A buyer managing Prialto is tracking hour consumption in addition to managing the work itself. For a sub-15-person service firm with a single founder and no dedicated operations manager, this model may be more structure than the situation requires.

Double, US-based fractional EAs for executives who need part-time flexibility

Double is the most flexible option in this comparison on commitment and minimum hours. Starting at $549 per month for 10 hours, it is designed for executives who need part-time coverage without locking into a full-time arrangement.

Who Double is actually built for

Double matches clients with US-, Canada-, or France-based college-educated EAs with an average of five years of executive support experience. The matching process accounts for location, task expertise, industry fit, and working style.

Double’s differentiation is its technology layer: a purpose-built delegation platform, desktop and mobile apps, and structured onboarding that includes tech setup support. This makes it a better fit for executives who want to use a structured tool environment rather than operating through email and Slack alone. The $300 onboarding fee covers matching, an onboarding call, tech setup support, and first-month check-ins.

Double was acquired by Zirtual in September 2024 and now operates under PennSpring Capital’s portfolio of VA providers. The withdouble.com brand and pricing remain active, but the service is no longer an independent company. Buyers comparing Double should factor in this ownership change when evaluating continuity risk, as the long-term direction of the brand has not been publicly disclosed.

Double pricing and commitment structure

Confirmed from withdouble.com/faq: plans start at $549 per month for 10 hours with no long-term contract required. Higher-tier plans reduce the effective hourly rate. Team plans are available for organizations bundling hours across multiple users. This is the most accessible entry point in this comparison for a buyer who wants to test before committing.

Where Double breaks down

Double is US-based, which means the cost per hour is higher than offshore alternatives. For a founder who needs full-time coverage, the economics at higher tiers are not materially better than offshore managed services, and the buyer does not get ICP-specific workflow training in the process.

Double also has no specialization in professional services industry workflows. A CPA firm owner will receive a generalist EA, not one trained in the specific tools and seasonal rhythms of an accounting practice. The Zirtual acquisition introduces continuity uncertainty that a buyer committing to a long-term arrangement should weigh explicitly.

Outsourced Scale, offshore EAs built specifically for CPA, payroll & HR firms

Outsourced Scale occupies a different position from the other three services. Rather than building a generalist EA model and selling it broadly, Outsourced Scale’s offshore EA model recruits, AI-trains, and embeds offshore EAs specifically for founder-led service businesses, with particular depth in CPA firms, payroll service companies, and HR consulting firms.

Who Outsourced Scale is actually built for

The OS buyer is a founder or owner of a sub-15-person service firm who is currently the bottleneck for marketing operations, client follow-through, and administrative execution. These buyers are not looking for a general executive partner. They need someone trained on their specific tools and processes, embedded in their daily workflow, and managed without the founder absorbing the HR overhead.

OS handles recruiting, AI training, integration into the client’s tools, and ongoing performance management. The buyer does not absorb the management overhead that comes with direct offshore hiring. That distinction matters for a firm with no dedicated operations manager, where every management relationship routes back to the founder.

Outsourced Scale pricing compared to the field

OS pricing runs at 60 to 70 percent less than Athena’s full-time rate and below Prialto’s full-time equivalent rate, while delivering full-time dedicated coverage. The how much an offshore EA costs in 2026 breakdown covers the full cost structure in detail. For a direct side-by-side on total cost of ownership, the offshore vs US-based EA cost comparison covers what each model actually costs when management time is included.

The trade-off versus Athena is the coaching layer: OS does not include executive coaching on how to delegate. The trade-off versus Prialto is the redundancy model: OS provides a dedicated individual, not a team pod. For buyers who already have documented workflows and want steady execution at a lower cost structure, OS fits. For buyers who need coaching on delegation or enterprise-grade redundancy with SOC-2 compliance, it may not.

What an AI-trained EA actually does differently

A generalist EA and one trained specifically on the tools and workflows of accounting and professional service firms are not the same hire. For a CPA firm owner, an EA who arrives knowing SmartVault, TaxDome, QuickBooks, and the seasonal rhythm of tax prep is a different category of support than one who needs workflow training from scratch. The onboarding period is shorter, the ramp time is lower, and the EA’s output is useful earlier.

The what an AI-trained EA can actually do resource covers the practical difference in capability, including which tool categories and workflow types the training addresses.

Where Outsourced Scale breaks down

OS does not fit buyers who need US-based availability for real-time in-person tasks. Buyers who require SOC-2 Type 2 compliance for enterprise security environments should look at Prialto instead. OS also does not offer fractional hour-by-hour plans, the model runs full-time embedded support only. Buyers who need 10 to 15 hours per month of light coverage will get more from Double’s entry-tier plan.

How to choose, matching provider to situation

The comparison comes down to four variables: how many hours you need, whether you want a dedicated individual or a team model, how much you can spend, and how much industry-specific workflow depth matters for your practice.

Decision map by situation

• Full-time support, high-volume founder, budget not the primary constraint, needs delegation coaching: Athena is the fit. The coaching layer and managed performance model are what justify the premium.
• Full-time or near-full-time support, enterprise or regulated environment, redundancy and SOC-2 compliance required: Prialto is the fit. The team pod model and compliance certification address requirements the other three services do not.
• Part-time support, US-based EA, flexibility and no long-term commitment required, lower volume: Double is the entry point, with the Zirtual acquisition noted as a continuity consideration.
• Full-time support, CPA, payroll, or HR firm, cost efficiency with ICP-specific workflow training, founder-led business with no dedicated ops manager: Outsourced Scale targets this buyer specifically.

The questions to ask before you book any demo

Before committing to any provider, get direct answers to these questions:

• What happens if my EA leaves or is unavailable? How long is the replacement process and who manages it?
• Is the pricing I see all-in, or are there setup fees, coaching fees, or platform fees that come later?
• What does onboarding look like in the first 30 days? What is my responsibility versus the provider’s?
• Who owns my day-to-day relationship: a dedicated individual or a team?
• Is there an early termination option, and what does it cost?

Ready to see which model fits your firm

If your firm is in the CPA, payroll, or HR services space and you have been comparing managed EA options, the pricing and ICP fit in this article should narrow the field. The right next step is not a generic demo. It is a conversation about what your firm specifically needs covered and whether the service can deliver it. To understand whether the investment makes sense for your situation, the whether the investment pays off resource walks through the calculation directly.

If your firm is in professional services and you want to see how Outsourced Scale compares to what you have already been looking at, a short conversation is the fastest way to get a direct answer. No presentation, no pressure, just a clear look at whether the fit makes sense. You can see if this is the right fit in 20 minutes.

FAQs About Choosing the Right EA Service

Q: How much does Athena executive assistant service cost?

Athena charges $3,000 per month on a 12-month commitment, totaling $36,000 per year for a full-time dedicated Executive Partner based in the Philippines working US business hours. A $24,000 buyout fee applies if the client wants to hire their assistant directly.

Q: What is Prialto’s pricing model?

Prialto prices in units of approximately 55 hours per month at $1,500 per unit, an effective rate of $27 per hour. Full-time equivalent coverage requires three units at $3,600 per month, with a 90-day minimum contract and setup fees waived on a one-year commitment.

Q: Is Double still operating as an independent company?

Zirtual acquired Double in September 2024, and the service now operates under PennSpring Capital’s portfolio. The withdouble.com brand and pricing remain active, with plans starting at $549 per month for 10 hours and no long-term contract required.

Q: What type of businesses is Outsourced Scale built for?

Outsourced Scale focuses on founder-led service businesses with fewer than 15 employees, particularly CPA firms, payroll service companies, and HR consulting firms. Outsourced Scale recruits, AI-trains, and embeds EAs in the client’s specific tools and workflows rather than placing them as generalist support.

Q: Which EA service is best for a small CPA firm?

For a small CPA firm, the relevant criteria are ICP-specific workflow training, cost structure relative to a full-time hire, and who handles management overhead. Outsourced Scale builds specifically for this buyer type; Athena and Prialto serve as generalist services that can work for CPA firms but do not specialize in their tools or workflows.

Q: What is the difference between a fractional EA and a full-time offshore EA?

A fractional EA provides support for a defined number of hours per month, useful for buyers with limited or variable administrative volume. A full-time offshore EA provides 40 hours per week of dedicated coverage at a cost well below a US-based equivalent. If you have 30 or more hours of recurring administrative work per week, a full-time offshore arrangement typically costs less in aggregate and delivers more consistency than hourly fractional plans.
