Complaint / review text:
I have gotten one client on thumbtack but that is it. I have received about 12 leads in two months.
However, I think most people are just price shoppers or not serious. Over half of the leads given to me, never even looked at the quote that I sent. However, you do get the credits back if they don't look at the quote. So don't ever buy their credit packages up front.
Just buy as you submit quotes because you will get the credit back.
So while I wouldn't make a big investment in them, I would at least try it by buying the credits up front.
