When renting out rooms over online services like Airbnb, property owners can use tools like PriceLabs, Smart Host, and Beyond Pricing to automatically adjust prices according to supply, demand, and other market variables.

Beyond Pricing, which launched in early 2014, is now available in 26 cities, and according to Techcrunch, it controls $1 million worth of Airbnb bookings a week. But Joe Fraiman and Andrew Kitchell still believe the market is underserved.

Today, their startup, the San Francisco-based PriceMethod, unveiled a new dynamic pricing tool for people who rent rooms over Airbnb and similar services. It's available in 60 U.S. markets, including San Francisco and New York, and property owners can try it for free.
