What is this?

A venture capital financial model that calculates founder secondary stock sales, equity ownership dilution, and net cash proceeds.

How does it work?

1. Enter company valuation, total shares, and founder shares owned. 2. Input target secondary dollar amount and price discount %. 3. Review post-secondary ownership % and estimated net cash after tax.

Why use it?

Helps founders de-risk personal wealth while understanding exact cap table ownership consequences.

Technical Scope & Calculation Limitations

Assumes common shares sold to secondary buyers; does not model complex conversion of common into preferred shares.
