* Liquid (www.doliquid.com) - Connects bicycle owners with visitors who want to rent a bike. Owners submit photos and details of their sweet chariot; Liquid verifies the offer, and then posts it online. Visitors search by location, bike size and type, then deal with the owner directly to rent their wheels. It's like AirBnB for pedalers! So far Liquid is in the US only, but it plans to branch out to 400 cities in 80 countries.

* Gidsy (www.gidsy.com) - “Gids” is the Dutch word for “guide.” The service matches locals who lead offbeat activities - say, mushroom hunting in an Austrian forest or snowboarding on a Washington mountain - with visitors looking for novel experiences of a place. Tour/activity prices are cheap compared to their professionally led counterparts. For details, read this article about a Gidsy guy who leads a food scavenging tour through New York City. Ashton Kutcher is an investor in the Berlin-based company (he also invests in AirBnB, by the way).
