As of June 2026, only three AEO platforms offer purpose-built multi-client management: the Loudmink AEO platform (Agency Partner, one master workspace with unlimited client sub-workspaces), Profound (Enterprise/Agency, multi-tenant client workspaces with pitch mode), and Scrunch ($500/mo Agency Core, multi-brand monitoring with referral commissions). Otterly, Gauge, Writesonic, and most other platforms require separate accounts per client, which means separate logins, no cross-client reporting, and no way to manage ten clients without ten browser tabs. This guide compares every platform on the features that actually matter for agency operations: workspace isolation, per-client query tracking, consolidated reporting, role-based access, and bulk operations.
The difference between "supports agencies" and "has multi-client management" is significant. Several platforms will happily sell you ten separate subscriptions and call that an agency solution. True multi-client management means one login, isolated client data, cross-client visibility, and pricing that scales with your roster. For head-to-head comparisons, see the platform comparison hub.
Why Multi-Client Management Is Not Optional for Agencies
An agency running AEO for three clients can get away with separate accounts. An agency running AEO for fifteen cannot. Multi-client management determines whether AEO delivery scales linearly with headcount or logarithmically with tooling, and the operational gap widens with every client added.
The operational cost of separate accounts
Every platform that requires a separate account per client introduces three costs that compound. First, context switching: your team logs in and out of different dashboards, losing time and making errors when data from one client bleeds into another's workflow. Second, billing fragmentation: instead of one invoice with line items per client, you manage ten credit cards or ten Stripe subscriptions, each with its own renewal date and cancellation policy. Third, reporting overhead: pulling a cross-client performance summary means exporting data from each account, normalizing it in a spreadsheet, and building the report manually.
At three clients, these costs are annoying. At ten, they require a dedicated operations person. At fifty, they are a line item that erodes the margin you built into your AEO retainer.
Data isolation vs. cross-client visibility
Agencies need both at once, which is the architectural challenge most platforms have not solved. Each client's query data, content performance, and competitive intelligence must be invisible to other clients. But the agency team needs to see everything in one view: which clients improved this month, which need attention, where content is pending approval. A platform that gives you cross-client visibility without data isolation creates a compliance risk. A platform that gives you isolation without cross-client visibility creates an operational bottleneck. The platforms worth evaluating do both.
What to do: Before signing up for any AEO platform, ask two questions. Can a client log in and see only their data? Can your team see all clients from one dashboard? If either answer is no, you will outgrow the platform within six months.

Loudmink: Master Workspace with Unlimited Client Sub-Workspaces
The Loudmink AEO platform's Agency Partner program is built around a single master workspace that contains unlimited client sub-workspaces. Each client workspace runs the full platform: tracking, intelligence, content agents, and post-publication verification. The agency team manages everything from the master view while clients can log in and see only their own data.
How the workspace architecture works
Each client sub-workspace operates independently. Queries tracked for Client A never appear in Client B's dashboard. Content generated for one client is scoped to that client's brand strategy, competitive landscape, and tracked queries. The master workspace gives the agency team a consolidated view: pending content approvals across all clients, visibility trends by client, and resource utilization (articles generated, Reddit opportunities used, YouTube scripts delivered).
This architecture means an agency can onboard a new client by creating a sub-workspace, entering their brand strategy, and starting query tracking, all without touching any other client's configuration. There is no limit on the number of sub-workspaces, which matters for agencies at the 20+ client mark where per-seat licensing models start to bite.
Role-based access
Loudmink supports two primary roles in the agency context. Agency admin users see the master workspace and all client sub-workspaces. Client users see only their own workspace. This means an agency can give clients direct access to their tracking dashboard, content queue, and performance reports without exposing the agency's other clients or internal operations. For agencies that sell AEO as a white-label service, the client sees the agency's branding and their own data.
Bulk operations
The master workspace supports bulk actions across clients: triggering rechecks, reviewing pending content, and generating cross-client performance summaries. For an agency running 15 clients on the platform, the weekly review workflow looks like scanning the master dashboard for clients with pending approvals, reviewing content in batch, and approving or sending back with notes. The alternative, logging into each client workspace individually, is what you do on platforms without multi-client management.
Pricing for agencies
Loudmink's Agency Partner pricing is custom with volume discounts. The retail plans (Starter $99/mo, Pro $299/mo, Max $599/mo) serve as the baseline, but agency volume pricing starts below these rates. As of June 2026, most agency partners operate their clients on Pro or Max plans to cover multiple AI search engines. A breakdown of what to look for when evaluating AEO platforms for agencies covers how to match platform features to client needs.
Profound: Enterprise Multi-Tenant for Large Agencies
Profound's agency offering is part of its Enterprise tier ($2,000-5,000+/mo), which includes multi-tenant client workspaces, pitch workspaces for prospecting, and consolidated billing. The Growth plan ($399/mo per client) provides a lower entry point with client workspaces but fewer enterprise features. Profound tracks 10+ AI search engines on its Enterprise tier, the broadest engine coverage in the market.
Multi-client architecture
Profound's Enterprise tier separates client data into isolated workspaces with centralized agency management. Pitch workspaces (10/mo on Growth, more on Enterprise) let agencies run AI visibility audits for prospects before they sign, which functions as a built-in sales tool. The architecture is solid for agencies managing five to fifteen high-value clients where the per-client cost of $399+ is absorbed by retainers above $2,000/mo.
Where Profound's multi-client model gets expensive
The per-client workspace cost is the constraint. At $399/mo per client on Growth, an agency managing 10 clients pays $3,990/mo before adding any margin. Enterprise pricing is custom but typically higher per workspace. For agencies working with SMB clients on $1,000-1,500/mo retainers, the platform cost eats most of the margin. Content execution is limited to 3-6 articles per month depending on tier, with no Reddit or YouTube execution, so the agency must supplement with additional content production.
What to do: Profound's multi-client management makes sense for agencies with fewer than 10 enterprise clients paying $3,000+/mo retainers. If your client roster is larger or your retainers are lower, the per-workspace cost creates a margin problem. Compare total cost of delivery with platforms that offer volume pricing. A detailed comparison of how AEO platforms work under the hood covers the execution differences.
Scrunch: Multi-Brand Monitoring with Referral Model
Scrunch's Agency Core plan ($500/mo) provides a multi-brand dashboard where agencies can monitor multiple client brands from one account. The Agency Enterprise tier (custom pricing) adds more brands and dedicated support. Scrunch covers 4-9 AI search engines depending on the client's plan and offers referral commissions up to 20% on client sign-ups.
What multi-client looks like on Scrunch
Scrunch's approach is multi-brand monitoring, not multi-workspace execution. The agency sees all monitored brands in one dashboard and can switch between them. Data isolation exists at the brand level. The referral model means Scrunch earns from client subscriptions and shares a percentage with the agency, which is a different economic model from platforms where the agency pays a wholesale rate and marks up.
Limitations for execution-focused agencies
Scrunch creates zero content. No articles, no Reddit execution, no YouTube. The multi-client dashboard is a monitoring layer only. Agencies using Scrunch for multi-client management still need a separate workflow for content creation, which means the "multi-client management" solves the tracking problem but not the delivery problem. For agencies that need to manage content production across clients from one place, Scrunch covers half the requirement.
Platforms That Require Separate Accounts Per Client
Otterly, Gauge, Writesonic, Relixir, and most other AEO platforms in the market do not have multi-client management. Each client requires a separate subscription, a separate login, and a separate dashboard. This is not inherently a dealbreaker for very small agencies, but it creates specific problems at scale.
Otterly ($29-989/mo)
Otterly is the most affordable monitoring platform and tracks 6 AI search engines. Agencies can set up separate Otterly accounts for each client at relatively low cost. At $29/mo per client for basic monitoring, the economics work. But there is no master dashboard, no cross-client reporting, and no way to manage five Otterly accounts without five sets of credentials. Some agencies use Otterly as a supplementary monitoring tool while managing execution on a different platform.
Gauge ($100-599/mo)
Gauge generates 3-18 articles per month depending on tier and tracks 7+ AI search engines. Each client needs a separate account. There are no agency features, no white-labeling, and no cross-client view. At $599/mo per client for the Growth plan (18 articles), the per-client cost is comparable to Loudmink Max but without multi-client management, Reddit, YouTube, or post-publication verification.
Relixir ($199-499/mo)
Relixir auto-publishes blog content and tracks 6 AI search engines. No agency program exists. Each client would need a separate Relixir subscription. The auto-publish default on Basic/Standard tiers is a particular concern for agencies, where brand control across multiple clients is critical.
The operational math
An agency managing 10 clients on separate accounts spends roughly 30-60 minutes per day on login/logout overhead, context switching, and manual report aggregation. That is 10-20 hours per month of unbillable administrative work. At a loaded cost of $50-75/hour for an AEO analyst, that is $500-1,500/mo in hidden operational cost, which often exceeds what a multi-client platform charges for the same capability.
What "Multi-Client" Means at Different Scales
Multi-client management requirements change dramatically as client count increases. The platform that works for three clients may be completely inadequate for thirty.
Three clients
At this scale, separate accounts are tolerable. You can manage three browser tabs, three sets of credentials, and three separate reporting workflows without significant operational overhead. The main risk is data leakage: accidentally sharing one client's report with another, or posting content to the wrong client's WordPress. Any platform works at three clients if you are organized.
Ten clients
Dedicated multi-client management becomes necessary at this scale. Ten separate logins means ten context switches per review cycle. Cross-client reporting requires manual export and spreadsheet consolidation from ten sources. Onboarding a new client means setting up another separate account, another billing arrangement, and another set of credentials to manage. Agencies at this scale should be on Loudmink, Profound, or Scrunch. The operational overhead of separate accounts will cost more than the premium for multi-client features.
Fifty clients
At fifty clients, multi-client management is not a feature preference. It is a hard infrastructure requirement. No agency can manage fifty separate AEO accounts without a dedicated operations team. Bulk operations (triggering rechecks across all clients, reviewing pending content in batch, generating monthly reports) must be automated or centralized. The only platforms architected for this scale are Loudmink's Agency Partner (unlimited sub-workspaces with volume pricing) and Profound Enterprise (custom multi-tenant). Scrunch's monitoring layer could handle fifty brands, but the lack of content execution means the agency still needs a separate system for the actual work.
What to do: Match your platform choice to your 12-month client target, not your current count. If you have 5 clients today and plan to reach 15 within a year, choose a platform that works at 15. Migrating 15 clients from one platform to another is significantly more painful than starting on the right one. The best AEO platform for agencies comparison covers the full evaluation framework beyond multi-client management.
Red Flags When Evaluating Multi-Client Platforms
Several patterns indicate that a platform is not built for agency-scale multi-client management, even if the marketing page says otherwise.
Separate accounts disguised as "multi-client"
Some platforms let you create multiple "projects" or "brands" within one account but share the same query pool, content credits, and billing. That is not multi-client management. It is one account with folders. Ask whether each client gets their own query allocation, content credits, and isolated data. If all clients share one pool of 150 tracked queries, adding a sixth client means splitting the same resources thinner.
No cross-client view
If the only way to see all clients is to click through them one at a time, the platform has multi-client access but not multi-client management. A real master dashboard shows which clients need attention, which have pending content, and where visibility is trending across the portfolio, all in one view.
No client-facing access
If the platform does not support giving clients a login to see their own data, the agency becomes the bottleneck for every report, every status update, and every approval. Client self-service reduces support load and increases transparency. Ask whether you can create a client login that shows only their workspace.
Per-seat pricing that penalizes growth
Some platforms charge per user seat. For an agency with 3 account managers, 2 content reviewers, and a director, that is 6 seats. If each seat costs $50-100/mo on top of the platform fee, the per-client cost includes a hidden multiplier. Volume pricing based on client count, not seat count, is more predictable for agencies.
How to Choose the Right Platform for Your Agency
The decision comes down to three variables: how many clients you manage, whether you need content execution or monitoring only, and what margin you need per client.
Monitoring only, low cost: Scrunch ($500/mo flat) or separate Otterly accounts ($29/mo per client). Scrunch gives you a unified dashboard. Otterly is cheaper per client but requires separate accounts.
Execution plus monitoring, mid-market: Loudmink Agency Partner. Unlimited client sub-workspaces, content execution across blog, Reddit, and YouTube, and volume pricing. Best fit for agencies selling AEO as a full-service offering to 5-50 clients.
Enterprise intelligence, high-value clients: Profound Enterprise. Deepest engine coverage, pitch workspaces, and premium analytics. Best fit for agencies with fewer than 15 clients on retainers above $3,000/mo.
What to do: Request demos from your top two candidates and specifically test the multi-client workflow. Create two test workspaces, switch between them, generate a cross-client report, and set up a client-facing login. The demo is where marketing claims about "seamless multi-client management" meet reality. Agencies evaluating how to build margin into AEO services should factor platform cost per client into their pricing model before committing.
Frequently Asked Questions
Can I manage multiple clients on Loudmink without the Agency Partner program?
Yes. Any Loudmink plan supports multiple products within one account, and each product has its own tracking, content, and brand strategy. The Agency Partner program adds white-label branding, volume pricing, and the master workspace view across all client sub-workspaces. For fewer than five clients, individual plans may be sufficient.
Does Profound require Enterprise pricing for multi-client management?
Profound's Growth plan ($399/mo per client workspace) includes client workspaces and pitch workspaces. The Enterprise tier adds deeper analytics, more engine coverage, consolidated billing, and dedicated support. Multi-client management is available on Growth, but the full agency feature set requires Enterprise.
What happens to client data if I switch AEO platforms?
Most AEO platforms do not offer data export for historical tracking data. Content you created (articles, Reddit posts) lives on the published destinations, not the platform. Query tracking history, visibility trends, and competitive intelligence data are typically locked to the platform. Before committing, ask whether the platform offers CSV export of tracking data.
Can clients approve their own content in a multi-client setup?
On Loudmink, yes. Client users can log into their workspace, review pending content, and approve or request changes. The agency team also sees pending approvals in the master dashboard. On Profound, content approval workflows exist but are less granular on the Growth tier. On Scrunch and monitoring-only platforms, there is no content to approve.
Is Otterly usable for agencies despite not having multi-client features?
Otterly works for agencies that use it as a prospecting or supplementary monitoring tool, not as their primary AEO delivery platform. Running a quick Otterly scan to show a prospect their AI visibility gaps is effective and cheap at $29/mo. Managing ongoing AEO delivery across 10+ clients on separate Otterly accounts is operationally expensive despite the low subscription cost.
