Build a Market Sizing Report in Hours (Claude Cowork Self-Install Kit)

Hand your client a sourced market sizing report the same day they ask for it.

Right now half your project timeline disappears into gathering numbers before you can write a single useful slide. And you are still not sure the figures will hold up when someone pushes back.

The framework was never your bottleneck. Pulling data by hand from a dozen tabs is, and that is a workflow gap, not a skill gap.

What this kit does

This kit sets up a research workflow that scopes a market on demand. You name the segment, the geography, and the year, and your agent runs a top-down TAM calculation with a bottom-up cross-check, names its sources, and flags anything thin. You get a structured TAM, SAM, and SOM table with assumptions documented, and what used to eat four to eight hours of research compresses to under 90 minutes of directed prompting on Claude, no connector required.

What you can expect

Expect to recover three to six hours on every market sizing engagement. You deliver a cite-able TAM, SAM, and SOM breakdown in one working session instead of spreading it across two days of tab-hopping. The numbers arrive with their sources attached, so they survive a second look.

Who it's for

Built for consultants, agencies, and solopreneurs who size markets for client decks and want the research done without losing a day to it. This is a self-install kit you run yourself with your own AI agent, built for Claude Cowork first.

What's included

Skip building from scratch. No coding. You get the complete kit your own AI agent reads, sets up, and runs for you, step by step:

• A Start Here guide, so you know exactly what to open first
• The agent install instructions, the part that lets your own AI agent stand the workflow up for you
• A guided setup that interviews you about your business, so the workflow fits how you actually work
• Workflow Briefing: the plan, the inputs, and what done looks like
• Task List your agent follows to build it
• MCP Connection Guide for the tools involved
• Tool Setup notes for accounts, keys, and permissions
• Prompt Library, including the ready-to-run prompt for this workflow
• Troubleshooting and maintenance guide for the common snags
• A Next Steps and Roadmap, so you know what to automate next once this one is running
• A Run Guide you keep, so you can run it any time with no setup again

This is a small kit that earns its keep on repetition. You install it once and rerun it for every new segment, geography, or client, so the setup pays for itself the second time you scope a market.

What you'll need (not included)

The kit is the workflow, the prompts, and the setup guide. To run it you bring your own Claude with Cowork account and the segment details you want sized. No extra tools and no connector are required beyond your Claude with Cowork account.

You'll also need your Claude account on Cowork's Pro plan or higher, so your agent can connect your tools and use the most capable model while it installs the workflow.

Not on Claude? The kit is plain files that describe what to achieve rather than which buttons to press, so a capable AI agent on another platform, like ChatGPT Work, can follow the same steps. If anything doesn't map to your setup, email support and we'll get you working.

How to install this kit

Open Claude Cowork and connect any tools the workflow uses at claude.com/connectors; this one needs none, so point your agent straight at the agent install instructions. It stands the workflow up and interviews you about your typical engagements as it goes.
