By default the app assumes your founding team will consist of 3 founders, a strategic hire and 1 employee. If your starting configuration is different, add or remove row entries as needed

Here is a dictionary that details the differences between each row entry that asks for options. If you are a founder or a VC, you will need to memorize these definitions in the course of your business

Term Definition
Options outstanding An outstanding stock option refers to an option contract that has not been exercised and has not expired. An example of this would be when you hire an employee sign a stock option contract with them. The option contract has not yet been exercised yet.
Promised Option Promised options mean options you haven’t officially granted to your team. These options could be in connection with a scope of work contract. Perhaps you signed a contract with a contractor where options would be part of the compensation conditional upon complete delivery of the agreed upon scope. And the work is currently in progress.
Options available These are options or essentially shares of your company not yet allocated to a person or to a stock option plan. Typically, when a startup is first formed there will be 10,000,000 shares created. If the company has not completed all of their hiring yet prior to a priced round, the remaining or “available” set of those shares would be rolled over to the sized option pool associated with the terms of the price round investment

Modify the numbers for each of the 3 row values for options. The total for all shares should sum up to 10,000,000 matching the number of shares specified on your Certificate of Incorporation (also known as your Articles of Incorporation).

The numbers in blue represent fields that you as a user should modify - they represent the input variables of the spreadsheet. The next step is to fill in the values for cells C16 and C18. They represent respectively the amount of capital they deploy into your company and the valuation cap associated. In this spreadsheet, we make the assumption that the Safe note contains no discount, and has a valuation cap. In the industry this is the most common case.

In this guide we assume that you will have 2 Safe investors. If there are more, you are able make a copy of the template
