It’s Saturday morning. Joel and Rebecca are walking their dog through a neighborhood in Austin, TX. As they walk, they chat about the movie they saw last night, what they’re going to make for dinner, and the big trip they have planned for next weekend. You wouldn’t know it by listening to their conversation, but the couple is also house hunting.

They cross Brodie Lane when Joel’s cell phone buzzes in his pocket. It’s a text message that reads:

Joel says to Rebecca, “We’ve got a match from our real estate company. It’s only four blocks away. Let’s go see what the house looks like.”

Within minutes, the couple is outside the 714 Longview Rd. home. It happens to be exactly the type of home they wanted, in the exact neighborhood they wanted to live in. They call their real estate agent to set up a viewing.

How did this happen? How was the couple instantly notified of the opportunity, perfectly merging buyer requirements, location and timing? The answer involves a combination of “geo-fencing,” mobile phones and GPS technology.
