# How to Find Companies by Technology with ChatGPT

ChatGPT discovers companies by their technology stack and explains what their tech choices reveal about their needs. It identifies complementary technology patterns that signal buying readiness, suggests positioning angles based on their current stack, and can generate tech-targeted outreach messaging for sales teams.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Find companies using React and TypeScript with 100+ developers"
3. ChatGPT searches for matching companies and presents results
4. Request: "Which of these are likely to need a component library?"
5. Ask for outreach suggestions tailored to their tech stack

## Example Prompt

```
Find companies using React and TypeScript in production. Suggest which ones would be good prospects for a UI component library.
```

## Tips

- ChatGPT can infer buying intent from technology combinations
- Ask it to explain why certain tech stacks signal readiness for your product
- Request outreach messaging that references their specific technology choices
