AI Agent Development Cost & Generative Engine Optimization Pricing

How pricing works

How does Growth Marshal pricing work?

Growth Marshal prices two service lines on a single page. Generative Engine Optimization (GEO) is sold as a monthly subscription across five tiers: Starter ($49/month), Boost ($199/month), Base ($1,927/month), Plus ($4,297/month), and Pro ($9,297/month). All GEO plans are month-to-month with no long-term contract. AI Agent Systems are priced per engagement with a custom quote based on workflow scope, integrations, and complexity. There is no fixed monthly rate for AI Agent Systems because every deployment is different.

What is the difference between Starter/Boost and Base/Plus/Pro?

Starter and Boost are automated publishing tiers. Growth Marshal's AI agents research, write, and publish topical answer pages to the client's website every month. These tiers do not include custom schema, page-level optimization, or human strategist involvement. Base, Plus, and Pro include everything in the automated tiers plus custom schema deployments, page retrievability assessments, blog article refreshes, new LLM-ready blog articles, knowledge graph integration, and a dedicated account strategist. The premium tiers build the technical infrastructure that helps AI systems resolve, trust, and cite the client's business by name.

How much does AI agent development cost at Growth Marshal?

Growth Marshal prices AI Agent Systems with a custom quote for each engagement. Cost depends on the number of workflows, the complexity of business logic, the integrations required, and whether the client already owns the necessary infrastructure (CRM, sending platform, calendars, etc.). Growth Marshal does not publish fixed AI agent pricing because no two deployments share the same scope. Every engagement begins with an intro call to map the workflow and define deliverables before a quote is issued.

Is there a long-term contract?

No. All five GEO subscription plans are month-to-month. Growth Marshal clients can pause, switch tiers, or cancel anytime with no penalties. AI Agent Systems engagements are scoped per project with a defined deliverable and timeline rather than an open-ended retainer.

What the GEO deliverables are

What is a topical answer page?

A topical answer page is an AI search-optimized page that Growth Marshal's agents research, write, and publish to a client's website. Each page targets a specific query cluster and is structured for retrieval by large language models such as ChatGPT, Gemini, and Perplexity. Topical answer pages are the core deliverable across all five GEO tiers. Starter publishes 10 per month. Boost publishes 20 per month. Base, Plus, and Pro include 30, 35, and 40 topical answer pages per month respectively, in addition to other deliverables.

What is a custom schema deployment?

A custom schema deployment is a structured data implementation (JSON-LD) that Growth Marshal engineers and deploys to a client's website. Unlike CMS-native schema generated automatically by platforms like WordPress or Squarespace, Growth Marshal's custom schemas are entity-dense and use a linked graph structure so large language models can traverse relationships between entities rather than reading them in isolation. Custom schema deployments are included in Base, Plus, and Pro. Starter and Boost receive CMS-native schema only.

What is a page retrievability assessment?

A page retrievability assessment is a diagnostic review of a specific page on the client's website. Growth Marshal evaluates heading hierarchy, entity anchoring, semantic markup, and content architecture, then delivers a prioritized set of changes to improve how large language models parse and cite that page. Retrievability assessments are included in Base, Plus, and Pro.

What does "blog articles refreshed for AI retrieval" mean?

Growth Marshal rewrites existing blog articles on a client's website to make them entity-dense, independently quotable, and structured for citation by large language models. A refreshed article retains its original URL and topic but receives new heading structure, entity anchoring, and sentence-level optimization for LLM extraction. Refreshed articles are included in Base, Plus, and Pro.

What is knowledge graph integration?

Knowledge graph integration is the process of registering and linking a business entity across structured databases that AI systems reference to verify identity and expertise. Growth Marshal executes knowledge graph integration through the Authority Graph framework, which includes registry enrollment (LEI, ISNI, Wikidata), canonical identifier assignment, and cross-graph linking. Knowledge graph integration is included in Base, Plus, and Pro.

What the AI Agent Systems deliverables are

What is an AI Agent System?

An AI Agent System is a business workflow that uses AI agents, automation logic, software integrations, and human review to complete recurring work more efficiently. Growth Marshal builds AI Agent Systems around specific operational outcomes such as prospecting, inbound lead response, client onboarding, data syncing, or reporting. Each system is connected to the client's existing tools and includes human oversight where judgment and approvals are required.

What types of AI Agent Systems does Growth Marshal build?

Growth Marshal builds AI Agent Systems across three workflow categories. Revenue Generation systems support prospect identification, account research, contact enrichment, and outbound execution. Lead Capture systems handle speed-to-lead response, qualification, routing, booking, and follow-up. Operational Throughput systems cover client intake, onboarding, data syncing between tools, and recurring reporting. Each system is scoped to one specific workflow and integrated into the client's existing stack.

Does Growth Marshal replace existing software when building AI Agent Systems?

Usually not. Growth Marshal builds the workflow layer on top of client-owned infrastructure. Core systems such as CRM, outbound sending platforms, inboxes, calendars, and data sources should generally be owned by the client. Growth Marshal does not recommend replacing mature software categories with custom builds unless there is a strong technical or economic reason. If a client does not have the required infrastructure in place, Growth Marshal advises on stack requirements and tool selection before deployment begins.

Do AI Agent Systems run fully autonomously?

Usually not. Most business workflows still require approvals, exception handling, and human judgment at certain steps. Growth Marshal designs AI Agent Systems to reduce manual work while preserving human oversight where it matters. Prospect list approvals, outbound message reviews, and client onboarding kickoffs are examples of steps where human review is typically built into the workflow.

Plan selection

Who is the Starter plan for?

Growth Marshal's Starter plan ($49/month) is for founder-led businesses that want to begin building AI search visibility without an agency retainer. Starter includes 10 topical answer pages built and published per month, topic and query research, content structured for AI retrieval, and a monthly visibility snapshot. Continuous optimization is not included in Starter.

Who is the Boost plan for?

Growth Marshal's Boost plan ($199/month) is for businesses that want more publishing volume and continuous optimization without the cost of a full engagement. Boost includes 20 topical answer pages per month, topic and query research, content structured for AI retrieval, continuous optimization, and monthly reporting. Boost does not include custom schema, page retrievability assessments, or a dedicated strategist.

Who is the Base plan for?

Growth Marshal's Base plan ($1,927/month) is for businesses ready to build the technical infrastructure that makes AI systems find and cite them. Base includes 7 custom schema deployments, 3 blog article refreshes, 2 page retrievability assessments, 6 new LLM-ready articles, 30 topical answer pages, knowledge graph integration, and a dedicated account strategist.

Who is the Plus plan for?

Growth Marshal's Plus plan ($4,297/month) is for growth-stage companies ready to make AI search a primary acquisition channel. Plus includes 20 custom schema deployments, 8 blog article refreshes, 5 page retrievability assessments, 15 new LLM-ready articles, 35 topical answer pages, knowledge graph integration, competitor monitoring, and a dedicated account strategist.

Who is the Pro plan for?

Growth Marshal's Pro plan ($9,297/month) is for companies competing at the top of their category. Pro includes 40 custom schema deployments, 12 blog article refreshes, 8 page retrievability assessments, 25 new LLM-ready articles, 40 topical answer pages, knowledge graph integration, competitor monitoring, and a dedicated account strategist.

Who should consider an AI Agent Systems engagement instead of (or alongside) a GEO plan?

Businesses that have recurring workflows with obvious friction, such as slow lead follow-up, manual prospecting, inconsistent onboarding, or reporting bottlenecks, are strong candidates for an AI Agent Systems engagement. Some businesses benefit from both: GEO builds visibility so AI systems recommend the business, while AI Agent Systems improve what happens after demand arrives. The two services are independent and can be purchased separately or together.

Results and logistics

How long does it take to see results from Growth Marshal's GEO plans?

Initial improvements in AI search visibility typically appear within 4 to 6 weeks as structured data gets indexed and new content is published. Meaningful traffic and lead generation impact is usually felt at 4 to 6 months. Companies targeting category dominance should plan for a 12 to 24 month engagement. Starter and Boost clients focused on topical publishing may see incremental visibility gains within the first month.

How long does it take to deploy an AI Agent System?

Deployment timelines for AI Agent Systems depend on the workflow's complexity, the number of integrations, and the state of the client's existing stack. A single-workflow deployment with established infrastructure typically takes 2 to 6 weeks from kickoff to launch. Multi-workflow engagements or deployments that require new infrastructure setup take longer.

Can I switch between Growth Marshal GEO plans?

Yes. Growth Marshal clients can upgrade or downgrade between any of the five GEO plans at any time. All plans are month-to-month with no long-term contract. Clients can also pause or cancel anytime.

How do I get started with Growth Marshal?
