Updated with new information from The Extraordinaries.

The Extraordinaries, a startup that lets users perform small, altruistic tasks on their mobile phones and web browsers, announced that it has raised $1.1 million in funding, including a just-closed round of $720,000.

The San Francisco company wants to help users take advantage of the small moments of free time they have during the day. The idea is that you may not have an entire Saturday afternoon to volunteer for a cause, but you probably have five minutes here and there — waiting for an appointment, maybe, or for the bus. With The Extraordinaries iPhone app (iTunes link), or on the beextra.org website, you can perform small tasks for nonprofits like mapping playgrounds for KaBoom. It’s a crowdsourced approach to volunteering, where lots of people can contribute tiny jobs to a larger project.

We featured The Extraordinaries in a post about online volunteering at the beginning of the year. It isn’t the only company bringing crowdsourced volunteering to the iPhone — Crowdflower and Samasource built an app called GiveWork and also teamed up to crowdsource emergency help for Haiti. But GiveWork is only one part of Crowdflower’s crowdsourcing business, whereas The Extraordinaries is really focused on micro-volunteering.

Investors include Kapor Capital, True Ventures, Alan Webber, James Currier, Ariel Poler, and Stan Chudnovsky.
