Most agency owners spend the first 20 minutes of every AI session re-explaining the client they're working on. Growth OS for Marketing Agencies fixes that permanently. Configure your agency once, then onboard each client into their own folder. Claude knows your services, your voice, and every client's business, audience, and brand, every time you start a conversation.
Built for Multi-Client Agencies
This plugin was built specifically for teams that manage multiple clients. It has a two-tier architecture: one-time agency setup plus repeatable per-client onboarding. Run the client onboarding for Client A, Client B, Client C. Each one gets their own workspace with their own documents. Client data never crosses folders. Your agency voice stays separate from each client's voice. And every morning, Claude scans all client folders to surface what needs attention across your entire book of business.
What's Included
Agency Setup (One-Time)
A 6-phase guided interview that configures your agency workspace. Claude crawls your website and social profiles, processes uploaded materials (proposals, case studies, pitch decks, brand guidelines), and builds core documents: service packages with pricing approach and delivery process, agency brand voice with pitching and collaborating registers, and a master CLAUDE.md that wires everything together. It understands retainer models, project-based work, team structure, and the difference between agency marketing and client work.
Client Onboarding (Run Per Client)
The headline feature. Say "/onboard-client" and Claude creates a dedicated folder, crawls the client's website and social profiles, and walks through 5 phases: client discovery, products and services, target customer persona with pain/pleasure mapping, brand voice, and growth ideas framed as agency deliverables. Each onboarding takes about 30 minutes. Do it for every new client. Claude uses a generic customer journey framework that adapts to whatever industry the client is in, so it works whether your client is a SaaS company, an e-commerce brand, a law firm, or a local restaurant.
Cross-Client Morning Briefing
A daily briefing designed for agencies. Claude scans all client folders, surfaces overdue tasks across every account, flags clients with no recent activity, shows onboarding progress for new clients, and suggests 3 things to work on. Categories rotate through new business, client delivery, agency marketing, operations, and client growth. This is your agency project manager showing up before your first meeting every morning.
Agency Growth Ideas
Separate from per-client work, the plugin generates 12-20 ideas for growing your agency's own pipeline. Uses a 10-stage Agency Client Journey framework (Problem Aware through Referral and Expansion) and covers all four objectives: Client Acquisition, Pipeline Conversion, Revenue Growth, and Retention and Referrals. Ideas are specific to your agency type: case study campaigns, Clutch profile optimization, LinkedIn thought leadership, referral programs, speaking engagements, and portfolio showcases.
Client Isolation
Built into the architecture, not bolted on. Each client's data lives exclusively in their own folder. Claude never cross-references one client's strategy, metrics, or content when working on another. When you switch clients, Claude loads the right context automatically. When you write a case study, it uses the agency voice. When you write a landing page for a client, it uses that client's voice.

What Happens After Setup
Run the agency setup once: Claude learns your services, voice, and team. Then say "/onboard-client" for each of your clients. In about 30 minutes per client, Claude has their business, audience, voice, and a growth plan ready to go. Say "good morning" for your daily cross-client briefing. Mention any client by name and Claude loads their context. Every new client you sign gets the same setup, every time.
