What Is Rahul Vohra's Email Product Superhuman?

On Acquired, Superhuman CEO Rahul Vohra called the product the fastest email experience ever built. Users get through an inbox about twice as fast as in Gmail, reply sooner to the mail that matters, and many hit inbox zero for the first time in years. Speed was the bet from the start, because Vohra was living in Gmail and watching it slow down. In year one the team put up a bare landing page. You left an address and got a note from Vohra asking what you used for email and what you hated about it. He expected complaints that Gmail was slow, weak offline, and dependent on plug-ins. That test drew about 5,000 signups.
