This week’s pick: startup UX timeline. A super simple and thus great directory that lists some of the most prominent tech startups and unicorns that have been evolving their customer experience and web presence over the years. I’ll walk you through a handful of them: starting at MVP and finishing up with present-day product design and web UIs. The UX timeline is a great website to bookmark for those who love to look back and consider trends, content design evolution and UX as a whole.

Note: we’re not affiliated with the tool makers. It’s just a great UX tool you should know about.

In this new weekly UX design, user research and product design tools series I’ll share some of the best picks I’ve encountered to date. You’ll find out about the best apps, extensions, websites and other helpful tools.
