auth0-check-for-domain-hook

In hook.js, you'll find a piece of code to ensure that new users' emails match certain criteria.

You'll have to deploy it as a "Pre User Registration" hook at https://manage.auth0.com/#/hooks.

Additionally, enable the "Force Email Verification" rule in https://manage.auth0.com/#/rules - otherwise, new users can sign in without confirming their email addresses first.

This script is meant to be used with a Google Sheets spreadsheet. When you edit a cell containing a
valid CSS hexadecimal colour code (like #000 or #000000), the background colour will be changed to
that colour and the font colour will be changed to the inverse colour for readability.

To use this script in a Google Sheets spreadsheet:
1. go to Tools » Script Editor » Spreadsheet;
2. erase everything in the text editor;
3. change the title to "Set colour preview on edit";

Who pays when startup employees keep their equity?

JD Maturen, 2016/07/05, San Francisco, CA

As has been much discussed, stock options as used today are not a practical or reliable way of compensating employees of fast growing startups. With an often high strike price, a large tax burden on execution due to AMT, and a 90 day execution window after leaving the company many share options are left unexecuted.

There have been a variety of proposed modifications to how equity is distributed to address these issues for individual employees. However, there hasn't been much discussion of how these modifications will change overall ownership dynamics of startups. In this post we'll dive into the situation as it stands today where there is very near 100% equity loss when employees leave companies pre-exit and then we'll look at what would happen if there were instead a 0% loss rate.

What we'll see is that employees gain nearly 3-fold, while both founders and investors – particularly early investors – get dilute
