500 Startups‘ second class of startups showed their stuff at the incubator’s Demo Day today in Mountain View, Calif. The incubator is run by Dave McClure, a super-angel who has invested in the likes of Mint.com and Twilio.

Here’s 500 Startups’ first batch of companies in its second class.

Vayable: Vayable connects individuals who want to go explore new places and “hosts.” Hosts are able to earn money by coordinating events like shopping tours in New York City or giving travelers a place to stay.
