A market sizing question answered in ClaudeYou ask Claude to size your market for 9,000 companies at an ACV of $24,000. Claude uses the ICP Intelligence connector. It answers: TAM 9,000 times $24,000 equals $216.0M; SAM $64.8M at a 30% ICP match; SOM $1.9M at a 3% year 1 share. The 30% and 3% are example figures to replace with your own.Claude, with ICP Intelligence connectedYouSize my market: 9,000 companies, ACV $24,000ClaudeUsing ICP Intelligence: TAM, SAM, SOMTAM: 9,000 x $24,000 = $216.0MSAM: $64.8M at a 30% ICP match (example)SOM: $1.9M at a 3% year 1 share (example)Example figures: replace with your own
A real answer from the ICP Intelligence connector. The question gave no match rate or share, so the tool used labelled examples.

Guides that use these tools

Worked examples from live runs of the Helix tools, with how to read each output and what to do next.

Use a B2B marketing tool in ChatGPT

Two connectors are also ChatGPT plugins. Install them from the ChatGPT plugin directory with no setup: Helix Positioning connects to the 8 IMPACT tools, and Helix Sales Enablement connects to the 12 Revenue Enablement tools.

For the other connectors, add a custom MCP server:

  1. Open ChatGPT Plugins and choose the option to add a custom MCP server. Your account and workspace must allow custom connections.
  2. Give the connection a name and paste one address below. Choose no authentication and review the connection notice.
  3. Create the connection, check the discovered tools and install it. Start a chat and select the connection with an @ mention, then ask your question using your own facts.

Menu names and plan access can change. Check the current OpenAI instructions.
