How do you find investors for a startup?
Start with the firms that lead the most rounds in your sector and stage, check their recent deals and check sizes, then find the partner to contact. This tool builds that list with each partner's email and flags firms that back your competitors.
Fill in the prompt
Edit the details in brackets with your sector, stage and round size, then pick the AI assistant to run it in.
Firecrawl Alexandria runs the lookups
Your assistant calls 4 tools in order, from Fireround, Apollo and FullEnrich, and cites the record behind every figure.
Get the answer
You get each firm's recent relevant deals and typical check, the partner's name, title and email, and any portfolio conflicts. Anything a source couldn't find is marked, not guessed.

Frequently asked questions
- How does it pick investors?
- It starts from the most active lead investors in your sector and stage over a recent window, then reads each firm's recent deals and typical check size.
- Does it flag conflicts?
- Yes. It lists portfolio companies that compete with yours so you can skip those firms.
- Is this tool free?
- Yes. The prompt, the steps and the instructions are free to use. When your assistant runs the tool through Firecrawl Alexandria, each data call bills its listed price in credits, and every data source shows that price before it's called.
- Which AI assistants can run it?
- Any assistant connected to Firecrawl with an API key, including ChatGPT, Claude, Claude Code, Codex and Cursor. Pick one in the prompt box and your request opens there with a link to this tool.
- Do I need to sign up?
- You need a Firecrawl account, with your assistant connected through its API key. Firecrawl Alexandria doesn't run in keyless mode. If your assistant isn't connected yet, the prompt tells it how to set that up. Some data providers ask an admin on your Firecrawl team to accept their terms before the first call.
