Work out SAFE conversions, dilution and option pool math for a funding round.
A cap table calculator for post-money and pre-money SAFEs, convertible notes and priced rounds. Muse can work out price per share, conversion prices, shares issued and each holder's fully diluted ownership, then hand back an Excel cap table and a PDF summary.
Try asking Muse: "If I raise $500k on an $8M SAFE and then a $5M round at $20M pre-money, what does my cap table look like?"

Zovo Cap Table Calculator is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
