Thanks for your comment ScottWhigham. If you've sold stuff on Craigslist/eBay, you would definitely know the value of such a service. The number of robo calls you get when you post your real phone number in ads is annoying. It doesn't end there - even weeks/months after your ad has expired and disappeared from Craigslist, you continue to receive marketing calls you didn't ask for and aren't interested in.

There is a reason why most people opt to use the anonymous email address that Craigslist provides while posting ads. We're only making it possible for people to have a similar experience with their phone numbers.

Okay - but both craigslist/ebay already have "protection" built in. They each have a proxy type of contact system already - craigslist even has a "roller" system if you will - the email.

If you learned tomorrow that craigslist had created exactly the same service and then added it to their ads, what then?

Scott, this is a risk for any idea. We believe that we will make it simple yet have lot of additional features that others don't have. If the service itself tries to implement this, it reinforces that we are solving a real problem :). We have our own business model and will continue to implement on them.
