- You deliver content marketing retainers and need to automate blog drafting, email writing, and social scheduling in client brand voice across Slack, email, and web interfaces.
- Your clients use Salesforce or HubSpot and need daily automated reporting, lead scoring, or pipeline summaries without manual CRM queries.
- You manage multiple client accounts and require white-label customer portals so clients interact with agents under your agency branding, not Stacker's.
- Your clients operate in healthcare, finance, or regulated industries requiring HIPAA, PCI-DSS, or FedRAMP compliance beyond SOC 2 Type II.
- You need agents to handle sensitive customer data without any human review step; Stacker agents operate autonomously and may require audit trails your clients demand.
- Your tech stack relies on proprietary or legacy systems without APIs; while Stacker supports computer use for web-based tools, deeply custom integrations may still require manual workarounds.

Platform Features
Core capabilities of Stacker
Autonomous task execution across tools
Agents connect to Salesforce, HubSpot, Airtable, Stripe, Notion, Google Sheets, Snowflake, Postgres, and 2,000+ other apps to pull data, execute workflows, and deliver results without manual intervention. Agencies resell this as a retainer service to handle client repetitive tasks like daily reporting, lead routing, and data synchronization.
White-label customer portals
Agencies deploy unlimited white-label portals so clients interact with agents under agency branding, not Stacker's. Included in Standard plan at $50/month, enabling agencies to present automation as proprietary IP and charge client retainers without exposing the underlying vendor.
Multi-agent coordination for complex workflows
Agencies can orchestrate specialist agents to hand off tasks across steps, so one agent pulls data, another analyzes it, and a third publishes results. Useful for content pipelines, lead qualification workflows, and end-of-month financial closes.
Content generation in brand voice
Agents draft publish-ready blog posts, emails, and social content using client style guides and past work samples. Agencies can automate content calendars and reduce client revision cycles by training agents on brand tone upfront.
Ad spend monitoring and optimization
Agents monitor campaign performance across channels, reallocate budget to top performers, and pause underperformers autonomously. Agencies can offer this as a managed service retainer without building custom dashboards or manual reporting workflows.
Scheduled and triggered automation
Set agents to run on a schedule (daily standups, Monday recaps, end-of-month reports) or trigger them via Slack, email, or webhook. Agencies reduce client support tickets by automating routine requests like 'send me yesterday's sales summary.'

Bottom Line
Stacker deploys autonomous agents that execute multi-step tasks across marketing, sales, finance, and operations by connecting to 2,000+ integrations including Salesforce, HubSpot, Airtable, and Stripe. Agencies can white-label customer portals and resell agent automation as a retainer service without building custom integrations.

The $50/month Standard plan includes unlimited agents and white-label portals, making per-client MRR viable for agencies bundling automation into service packages.
Reality Check
Stacker agents require clear task definition and connected data sources to function; vague or poorly structured requests may produce incomplete results. Agencies reselling to non-technical clients must provide ongoing prompt engineering and workflow refinement, adding support overhead. SOC 2 compliance is confirmed, but HIPAA certification is not mentioned, limiting use cases in healthcare or regulated verticals.

Core concepts
The mental model you need to price and scope the work.
- Wiring Over WidgetsConcept
The AI agent itself is a commodity, but the value for agencies lies in the integration layer: connecting a pre-built agent to a client's CRM, calendar, and review cycle. This framework shifts focus from selecting the 'best' agent to mastering the wiring process. For example, an agency using Vendasta's white-label AI receptionist for a local business must configure it to match the client's booking rules and follow-up cadence, turning a generic tool into a tailored service. As agentic AI adoption grows (77% of decision-makers now run agents in production), clients expect this customization. Agencies that treat agents as components and invest in repeatable wiring processes can charge retainers for ongoing optimization, rather than one-off setup fees.
- Wiring Over WidgetsConcept
The AI agent market sells finished workers, but the strategic value for agencies lies not in the agent itself, which is increasingly a commodity, but in the wiring that connects it to a specific client's CRM, calendar, and review cycle. This framework, 'Wiring Over Widgets,' argues that agencies that treat agents as components rather than products win. The agent is the widget; the wiring is the integration, customization, and ongoing optimization that turns a generic tool into a tailored solution. For example, a white-label platform like Vendasta provides AI employees, but the agency's role is to configure them for each local business's unique lead flow and follow-up process. This wiring is where retainer pricing originates, as it requires ongoing maintenance and adjustment. Recent research shows that 88% of B2B marketers face foundational gaps, meaning clients need help not just deploying agents, but ensuring their operations can support them. Agencies that master the wiring can charge a premium for the irreducible value they add.
- Integration MoatConcept
The Integration Moat framework holds that the durability of an AI agent engagement is determined by how deeply the agent is wired into a client's existing systems, not by the agent's underlying capability. Since the agent itself is increasingly a commodity, the switching cost for the client lives in the integrations: the CRM fields mapped, the calendar sync, the review-cycle triggers, and the exception-handling rules. Agencies that invest in this wiring create a moat that competitors offering generic agents cannot cross. For example, a white-label platform like Vendasta lets an agency deploy an AI receptionist for a local business, but the real value is in configuring it to the client's booking flow and follow-up cadence. With 77% of AI decision-makers now running agentic AI in production, clients expect this depth, and agencies that deliver it convert one-off projects into retainers.

- Productized Agent Service vs Custom Agent BuildDecision Framework

Frequently Asked Questions
Answers about pricing, setup, implementation
Stacker deploys AI agents that autonomously execute multi-step business tasks by connecting to your existing tools and data sources. Agents pull and summarize data from Salesforce, HubSpot, Airtable, Stripe, and 2,000+ other apps; generate publish-ready content in brand voice; monitor and optimize ad spend; schedule and post content across platforms; send and reply to emails; and coordinate multiple specialist agents for complex workflows. Agencies resell agents as retainers to automate client marketing, sales, finance, and operations workflows.
Stacker offers 2 pricing tiers, at $50/mo (Standard). Agencies typically achieve 74% profit margins when reselling to clients.
Yes. Stacker includes white-label customer portals in the Standard plan at $50/month, allowing agencies to deploy unlimited branded portals so clients interact with agents under your agency name, not Stacker's. This enables agencies to present automation as proprietary IP and charge client retainers without exposing the underlying vendor.
Yes. Stacker natively supports both Salesforce and HubSpot as core integrations. Agents can pull and write data to both CRMs, enabling agencies to automate lead scoring, pipeline reporting, contact enrichment, and deal tracking without manual CRM queries or external data tools.
Setup time depends on workflow complexity and data source configuration. Connecting a single tool like HubSpot or Slack typically takes 5-10 minutes per client account once the agency parent account is configured. More complex workflows involving multi-step agent coordination or custom data transformations may require 30-60 minutes of initial prompt engineering and testing. Standard plan includes unlimited agents, so agencies can build and test workflows before deploying to clients.
Stacker is built for marketing agencies automating content creation and ad spend optimization, operations teams handling repetitive data tasks, SMB service businesses managing client workflows, and real estate agencies automating lead nurturing and property listing updates. Any client with repetitive tasks across connected tools (CRM, spreadsheets, email, ad platforms) is a fit.
Stacker agents operate autonomously without built-in approval gates. For high-stakes workflows like financial reconciliation, legal document generation, or customer data handling, agencies should implement manual review steps or configure agents to flag decisions for human sign-off before execution. SOC 2 compliance is confirmed, but agencies should audit agent outputs in regulated verticals before deploying to production.
Stacker does not publish explicit data retention or export policies in available documentation. Agencies should confirm data ownership and export procedures with Stacker sales before signing client contracts, especially if clients store sensitive information in connected tools or expect data portability on contract termination.
