Overview

AI-generated overview

Ranks public VC firms for a startup from a short description and returns firm profiles, helping founders build an investor list for a fundraise.

What you can do
  • Find and rank up to 20 public VC firms for a startup from a short description, with similar companies each firm backed
  • Read one firm's public profile: location, website, thesis, stages, check size, sectors, geographies and recent portfolio companies
  • Email the founder a personal link to F4's free, longer report form with the description pre-filled
When to use it
Useful when a founder asks which venture capital investors to pitch, wants an investor list for a fundraise, or asks which VC firms back a certain kind of startup. Not intended for fundraising mechanics such as SAFEs, valuation or dilution, or for investor contact details.
Requirements
Remote endpoint at app.f4.fund over streamable HTTP; no sign-in or API key is needed. Stage, round size and location are used only when the founder states them.
Before you install
The email tool sends a message to an address the founder supplies, so confirm the address before calling it. Firm and company names come from public records and may be incomplete, and results include links to F4's report form.

Installation

In SourceWeft

  1. Open F4 Raise in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/fund.f4%2Fraise/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

find_vc_firms

Find VC firms

Use this when a founder asks which venture capital investors to pitch, wants an investor list for a fundraise, or asks which VC firms back a kind of startup. Not for fundraising mechanics such as SAFEs, valuation or dilution, or for investor contact details. Ranks up to 20 public VC firms for a startup from a plain-language description of 10 to 500 characters. Each firm comes with up to three public companies it backed that resemble the startup, and a link to its F4 page. The result also carries one link to a free, longer report on f4.fund built from the company's pitch deck, which ranks about 100 firms. The optional stage removes firms whose stated stages are all two or more steps away from it, so a firm one stage away can remain. The optional round size removes firms whose smallest cheque is more than twice the round. The optional location lists firms whose stated geography excludes it after the firms that invest there. These are applied only when given. The optional website is used for its domain, and its home page may be read. F4 stores the description, website domain, stage and round size to fill in the report form and count how the plugin is used. Each call saves a new search and prefilled report link. It sends no email and contacts no firm, and it returns no contact details.

get_vc_firm_details

Get VC firm details

Use this when the user asks about a specific VC firm by name, or about a firm in a find_vc_firms result. Returns the public profile of one VC firm: name, location, website, a short thesis, the stages it has invested at, check size, sectors, geographies and up to 10 recent public portfolio companies. The firm is a slug from a find_vc_firms result or a name. It returns no contact details and no team names, and it covers only firms that have a public F4 page.
