Don't you love that little "Add to calendar" button? You just click it from an event announcement or invite, and it automatically puts the event information on your calendar. No cutting and pasting needed.

Redwood City, California-based Stanza, formerly known as SpotOn.it, is taking the add-to-calendar button to the next level.

The startup's Add-To-Calendar button can integrate with any calendar client (Google, iCal, Outlook, Exchange, etc.). But it does some tricks that older, static calendar buttons can't do.

Stanza's button can:

  • Connect information to a calendar event, like score updates after a sporting game, or recipes after a cooking class
  • Connect services to a calendar event that allow users to do things like buy tickets, or upgrade their seats once at the event, or order an Uber to the event
  • Automatically show the right information to each calendar end-user, based on the users' time and location context
  • Return engagement and analytics data back to the publisher
According to the company, more than 300 sports teams (from the NFL, NBA, NHL, and NCAA) already have adopted the button. The button has already been used to sync more than 56 million sporting events to users' personal calendars, Stanza says.

Stanza has just closed a $4.3 million seed funding round, with participation from Metamorphic Ventures, Founder Collective, Tekton Ventures, Western Technology Investment, and Stanford-StartX Fund, along with a group of angel investors. Stanza says it will use the money to expand its customer base beyond sports teams.

Stanza is available for a limited preorder from now until late summer 2015, at a price of $7 per month for the first year. After the limited preorder, the price goes up to $15 per month.

Stanza was founded by CEO Smita Saxena in 2012.
